v1.0.beta7 2006-04-12  Timo Sirainen <>

	+ Added shutdown_clients setting to control if existing imap/pop3 
	  processes should be killed when master is.
	- Master login fixes, PLAIN authentication was still broken..

v1.0.beta6 2006-04-12  Timo Sirainen <>

	* The login and master usernames were reversed when using
	  master_user_separator (now the order is UW-IMAP compatible).
	* Killing dovecot master process now kills all IMAP and POP3
	  processes also.

	+ -a parameter to dovecot prints now all settings that Dovecot uses.
	  -n prints all settings that are different from defaults.
	+ Added pop3_lock_session setting
	+ %M modifier returns string's MD5 sum. Patch by Ben Winslow
	- PLAIN SASL authentication wasn't working properly, causing failed
	  logins with some clients (broken in beta4)
	- Fixes to Maildir++ quota, should actually work now
	- Don't crash if passwd-file has entries without passwords
	  (eg. deny=yes databases)
	- Fixed prefetch userdb to work nicely with other userdbs
	- If master process runs out of file descriptors, don't go to
	  infinite loop (unlikely to have happened unless the OS's default
	  fd limit was too low)
	- Fixed non-plaintext password lookups from LDAP. Patch by Lior Okman
	- %U modifier was actually lowercasing the string. Patch by Ben Winslow

v1.0.beta5 2006-04-04  Timo Sirainen <>

	- Beta4's SSL proxying rewrite worked worse than I thought.
	  Reverted it back to original code.

v1.0.beta4 2006-04-02  Timo Sirainen <>

	* Changed the default lock_method back to fcntl. Apparently flock
	  gives problems with some systems.
	* mbox: mailboxes beginning with '.' are now also listed
	* Replaced mail_use_modules and mail_modules settings with mail_plugins
	  and mail_plugin_dir. Now instead of loading all plugins from the
	  directory, you'll have to give a list of plugins to load. If the
	  plugin couldn't be loaded, the process exits instead of just
	  ignoring the problem (this is important with ACL plugin).

	+ Added support for "master users" who can log in as other people.
	  The master username can be given either in authorization ID
	  string with SASL PLAIN mechanism or by setting
	  auth_master_user_separator and giving it within the normal username
	+ Added ACL plugin with ACL file backend. This however doesn't mean
	  that there yet exists a proper shared folder support. If master user
	  logged in as someone else, the ACLs are checked as the master user.
	+ Added some Dovecot extensions to checkpassword passdb, see ChangeLog
	+ Updated passwd-file format to allow specifying any key=value fields
	+ Maildir++ quota support and several quota fixes
	+ passdb supporting extra fields: Added "allow_nets" option which takes
	  a comma separated list of IPs/networks where to allow user to log in.
	+ NFS: Handle ESTALE errors the best way we can
	+ IMAP now writes to log when client disconnects
	+ In shared mailboxes (if dovecot-shared file exists) \Seen flags are
	  now kept only in index files, so as long as each user has a separate
	  index file they have separate \Seen flags.
	- Fixes to DIGEST-MD5 realm handling so it works with more clients
	- BODYSTRUCTURE -> BODY conversion from cache file was broken with
	  mails containing message/rfc822 parts.
	- Fixed several memory leaks
	- We could have sent client FETCH notifications about messages before
	  telling about them with EXISTS
	- Compiling fixes for Solaris and some other OSes
	- Fixed problem with internal timeout handling code, which caused eg.
	  outlook-idle workaround to break.
	- If /dev/urandom didn't exist, we didn't seed OpenSSL's random number
	  generator properly. Patch by Vilmos Nebehaj.
	- Maildir: Recent flags weren't always immediately removed from mails
	  when mailbox was opened.
	- Several changes to SSL proxying code, hopefully making it work

v1.0.beta3 2006-02-08  Timo Sirainen <>

	* Dotlock code changed to timeout faster in some situations when
	  the lock file is old.
	+ Added support for loading SQL drivers dynamically (see INSTALL file
	  for how to build them)
	+ Keywords are stored to dboxes, and other dbox improvements.
	+ dict-sql could actually work now, making quota-in-sql-database
	  possibly working now (not fully tested)
	+ Added mail storage conversion plugin to convert automatically from
	  one mailbox format to another while user logs in. Doesn't preserve
	+ Added plugin { .. } section to dovecot.conf for passing parameters
	  to plugins (see dovecot-example.conf).
	+ Added ssl-build-param binary which is used to generate
	  ssl-parameters.dat. Main dovecot binary doesn't anymore link to
	  SSL libraries, and this also makes the process title be clearer
	  about why the process is eating all the CPU.
	- Fix building without OpenSSL
	- Fixed memory leak in MySQL driver
	- Fixes to checkpassword
	- Broken Content-Length header could have broken mbox opening
	- Fixed potential hangs after APPEND command
	- Fixed potential crashes in dovecot-auth and imap/pop3-login
	- zlib plugin now links with -lz so it could actually work
	- kqueue fixes by Vaclav Haisman

v1.0.beta2 2006-01-22  Timo Sirainen <>

	+ Added SQLite support. Patch by Jakob Hirsch.
	+ Added auth_debug_passwords setting. If it's not enabled, hide all
	  password strings from logs.
	+ Added mail_cache_min_mail_count and mbox_min_index_size settings
	  which can be used to make Dovecot do less disk writes in small
	  mailboxes where they don't benefit that much.
	+ Added --build-ssl-parameters parameter to dovecot binary
	- SSL parameters were being regenerated every 10 minutes, although
	  not with all systems.
	- Fixed dovecot-auth crashing at startup. Happened only with some
	  specific compilers.
	- base_dir was supposed to be set world-readable, not world-writable

v1.0.beta1 2006-01-16  Timo Sirainen <>

	* Almost a complete rewrite since 0.99.x, but some of the major
	  changes are:

	+ Index file code rewritten to do less disk I/O, wait locks less and
	  in generate be smarter. They also support being in clustered
	  filesystems and NFS support is mostly working also.
	+ Mail caching is smarter. Only the data that client requests is
	  cached. Before Dovecot opened and cached all mails when mailbox was
	  opened the first time, which was slow.
	+ Mbox handling code rewritten to be much faster, safer and correct
	+ New authentication mechanisms: APOP, GSSAPI, LOGIN, NTLM and RPA.
	+ LDAP supports authentication binds
	+ Authentication server can cache password database lookups
	+ Support for multiple authentication databases
	+ Namespace configuration
	+ Dovecot works with shared 

v0.99.10 2003-06-26  Timo Sirainen <>

	* Default PAM service name changed to "dovecot". This means that
	  if you're using PAM, you most likely have to do
	    mv /etc/pam.d/imap /etc/pam.d/dovecot
	  If you wish to keep using imap, see doc/auth.txt.

	* ~/rawlog directory changed to ~/dovecot.rawlog

	+ Faster and better maildir synchronization. We support read-only
	  maildirs and out-of-quota conditions are handled a lot better.
	  dovecot-uidlist file still isn't out-of-quota-safe though, but you
	  can keep it in another location where quota isn't checked. For
	    default_mail_env = Maildir:~/Maildir:
	+ Read-only mboxes are supported now.
	+ Only NOOP and CHECK now always do a mailbox sync checking. Other
	  commands sync max. once in 5 seconds, plus always from indexes.
	  This should reduce I/O a bit.
	+ All NUL characters are translated to ascii #128 before sending to
	  client. RFC prohibits sending NULs and this is how UW-IMAP handles
	  it as well.
	+ Make ENVELOPE, BODY and BODYSTRUCTURE replies more compact by
	  removing multiple LWSPs and translating TABs to spaces. RFC doesn't
	  specifically require this, but this seems to be the wanted
	+ Added ANONYMOUS SASL mechanism.
	+ More flexible user chrooting configuration in home directories:
	+ Added support for dynamically loadable IMAP/POP3 modules. See
	  INSTALL file for more information.
	- Partial fetches were broken if mails had CR+LF linefeeds
	- SEARCH DELETED didn't return anything if all messages were deleted
	- OpenSSL support was broken in many installations because we were
	  chrooted and it couldn't open /dev/urandom.
	- PAM: Giving wrong password blocked the whole process for two
	  seconds. Now we create a new process for each check.
	- Lots of other smaller bugfixes and better error handling

v0.99.9.1 2003-05-03  Timo Sirainen <>

	- Messages having lines longer than 8192 bytes caused problems.
	- There was some problems when opening a mbox first time that had been
	  empty for a while.
	- Didn't compile with OpenBSD.
	- POP3 server crashed sometimes instead of printing error message.
	- If cached IMAP envelope contained literals, SEARCHing in it wrote
	  errors to log file. For example if subject contained highascii, '"'
	  or '\' characters this happened.

v0.99.9 2003-04-28  Timo Sirainen <>

	* WARNING: mbox rewriting works now faster, but it's less likely to
	  notice external message flag changes (it wasn't perfect before
	  either). This also means that if you're not using index files,
	  Dovecot may not notice changes made by another Dovecot process.
	  This will be fixed later.

	+ Message UIDs are now permanently stored outside index files.
	  Deleting indexes is now possible without any kind of data loss and
	  in-memory indexes are now usable.
	+ mbox rewriting leaves extra space into X-Keywords header. It's
	  shrinked or grown when updating message flag headers to avoid
	  rewriting the rest of the file.
	+ imap-login and pop3-login can now be started from inetd. Privilege
	  separation is still used, so it executes dovecot and dovecot-auth
	  processes which are left on the background.
	+ PostgreSQL authentication support, patch by Alex Howansky
	- Large multiline headers (over 8kB) broke Dovecot before. Now they're
	  parsed one line at a time and we try to avoid reading them fully into
	- SEARCH OR was broken
	- Partial BODY[] fetches were broken
	- Timezones were still set wrong when parsing dates
	- Using non-synchronized literals (LITERAL+) broke APPEND
	- Renaming maildir subfolders inserted extra "." in the middle.
	- Subfolders were a bit broken with maildir
	- Invalid PLAIN auth request crashed auth process.

v0.99.8 2003-02-25  Timo Sirainen <>

	* NOTE: Configuration file has changed a bit: auth_userinfo was
	  replaced by userdb and passdb. *_port were merged into *_listen.
	  Disabling listening in imaps port is now done by changing protocols

	* Maildir: .customflags location has changed for INBOX. If you have
	  set any custom flags, move Maildir/.INBOX/.customflags into
	  Maildir/.customflags or they will be lost.

	* mbox: Autodetect /var/mail/%u and /var/spool/mail/%u as INBOXes
	  if they're found and mail_default_env isn't set.

	* passwd-file: File format changed a bit. If you used realm or mail
	  fields, you'll have to fix the file. See doc/auth.txt for description
	  of the format.

	+ Fully featured POP3 server included. Disabled by default.
	  LISTEXT extensions.
	+ LDAP authentication support.
	+ Internal API cleanups made Dovecot faster and take less memory
	+ auth_verbose logs now all authentication failures
	+ Support for Solaris 9 sendfilev()
	+ New setting: mail_full_filesystem_access allows clients to access the
	  whole filesystem by simply giving the path before the mailbox name
	  (eg. SELECT ~user/mail/box, LIST "" /tmp/%). While this allows users
	  to share mailboxes, it's not recommended since Dovecot's index files
	  can't be safely shared.
	+ New setting: client_workarounds.
	+ Dynamically loadable authentication modules. Binary package builders
	  should consider using it for at least LDAP.
	+ mbox: Content-Length is saved now to each saved message, so it's
	  now safe to have lines beginning with "From ".
	+ mbox: mail_read_mmaped = no works with it now
	+ Indexes can be kept in memory by adding :INDEX=MEMORY to MAIL
	  environment. There's not much point to do this now though, since the
	  UIDs won't be saved.
	- COPY now behaves as RFC2060 says: "If the COPY command is
	  unsuccessful for any reason, server implementations MUST restore the
	  destination mailbox to its state before the COPY attempt."
	- LIST and LSUB rewrite, should fix several bugs in them
	- maildir_copy_with_hardlinks = yes was broken.
	- mboxes in subfolders weren't selectable.
	- STORE didn't accept multiple flags without () around them
	- PLAIN SASL-authentication was a bit broken.
	- IMAP dates were parsed a few hours wrong
	- STATUS command removed \Recent flags from messages
	- Several bugfixes to SEARCH command, especially related to multiple
	  search conditions
	- If auth/login process died unexpectedly at startup, the exit status
	  or killing signal wasn't logged.
	- mbox parsing might have crashed sometimes
	- mbox: when saving mails, internal headers were allowed in input,
	  sometimes causing problems (eg. duplicate headers) when appending
	  and copying messages
	- mbox: X-Keywords headers were duplicated
	- Some small fixes to how messages are saved to Maildir
	- Next command after STARTTLS was ignored which left the connection
	  stuck sometimes
	- Dovecot was pretty much broken with FreeBSD

v0.99.7 2003-01-14  Timo Sirainen <>

	+ Rewrote doc/index.txt, small updates to doc/design.txt and
	- New hash table code was broken with removing, which broke several
	  things. Fixed, but it's still a bit ugly code though..

v0.99.6 2003-01-13  Timo Sirainen <>

	+ THREAD=REFERENCES extension support. ORDEREDSUBJECT would be easy to
	  add, but I think it's pretty useless.
	+ SORT is much faster now.
	+ mbox: If ~/mail directory isn't found, create it.
	+ Log login usernames
	* Some coding style changes (less typedefs)
	- Mails with nested MIME parts might have caused incorrect BODY and
	  BODYSTRUCTURE fetches and sometimes might have crashed dovecot
	  (assert at imap-bodystructure.c). If client had already successfully
	  done the BODY fetching a couple of times, the bug couldn't happen
	  anymore since Dovecot then began caching the BODY data. So, this
	  mostly happened with new users.
	- non-UID SEARCH might gave wrong replies in certain conditions.
	- SORT replied always with UIDs instead of sequences.
	- If authentication was aborted by client ("*" reply to AUTHENTICATE),
	  the login process crashed later.
	- STATUS command gave invalid reply for mailboxes with spaces in name
	- Timezones were parsed wrong with message dates
	- Digest-MD5: We used "qop-options" instead of "qop", which was
	  incompatible with at least Cyrus SASL.
	- Realms in passwd-file were buggy
	- Literals didn't work when logging in
	- Crashed if it had to wait for mbox lock
	- With invalid configuration auth and login processes were just dying
	  and master filling log files infinitely.
	- We didn't work with some 64bit systems

v0.99.5 2003-01-02  Timo Sirainen <>

	* This release includes a lot of code cleanups, especially related to
	  security. Direct buffer modifying was replaced in several places
	  with a new buffer API, which provides a safe way to do it. Code that
	  looks unsafe contains @UNSAFE tag to make auditing easier.

	+ Support for SORT extension. Originally I thought about not
	  implementing any extensions before 1.0, but too many people want
	  webmails which want SORT. THREAD is another extension which they
	  want, but we don't support it yet.
	+ imap_listen and imaps_listen settings now accept "*" and "::" to
	  specify if we want to listen in IPv4 or IPv6 addresses. "::" may
	  also listen in all IPv4 addresses depending on the OS (Linux does,
	  BSD doesn't)
	+ New setting: default_mail_env can be used to specify where to find
	  users mailbox. Default is still to use autodetection.
	+ New setting: imap_log_path to log logins etc. informational messages
	  to different file.
	+ We support now separate mbox file for INBOX folder, no need for
	  symlink kludging anymore.
	+ Support for keeping index files in different location than actual
	? Disabled mailbox_check_interval setting by default, it breaks
	- SEARCH was still somewhat buggy, especially with laggy networks.
	  Also body/header searches might have crashed or at least used
	  memory too much
	- Deleting messages in the middle of mbox caused dovecot to reindex
	  the following messages as new messages (ie. change UIDs and set
	  \Recent flag).
	- Digest-MD5 auth: Initial server challenge packet was missing a comma,
	  which might have made it incompatible with some implementations.
	- Some more fixes to unnecessarily high memory usage
	- SELECT and EXAMINE often printed UNSEEN reply or maybe complained
	  about corrupted indexes. Happened usually only with mbox.
	- FETCH BODYSTRUCTURE gave incorrect reply, breaking pine
	- LIST was pretty buggy with mbox subfolders
	- CHECK command returned just "missing parameters" error
	- DELETE didn't work with mbox folders
	- CREATE mailbox<hierarchy separator> failed always.
	- CREATE and RENAME didn't create required hierarchies with mbox
	- RFC822 date parser didn't handle single digit days correctly.
	- login_process_per_connection = yes didn't work with imaps port
	  connections which is exactly where it was mostly wanted.
	- ssl_disabled = yes didn't disable listening in imaps port
	- process limiting code didn't compile everywhere (eg. FreeBSD).
	- Linux sendfile() was never detected
	- We didn't work at all with gcc/PowerPC

v0.99.4 2002-12-01  Timo Sirainen <>

	- Command parser had several bugs when it didn't have enough data to
	  parse the full command in one call, ie. network lags etc. triggered
	  those bugs sometimes. This was the last "weird bug" I know of.
	- Mbox indexes got broken when updating cached fields
	- Fixed a few memory leaks and unneededly high memory usage while
	  caching envelopes
	- Fixes to searching from message body and header
	- --with-ssldir didn't do anything and the default was empty

v0.99.3 2002-11-26  Timo Sirainen <>

	- mail_read_mmaped = no (default) caused mbox corruption with EXPUNGE.
	  mmap()ing is forced for now.

v0.99.2 2002-11-26  Timo Sirainen <>

	+ If we have to wait for a lock longer, the client is now notified
	  about it every 30 seconds.
	- Default settings still pointed to lib directory instead of the
	  libexec directory where the binaries were actually installed
	- vpopmail support had to be kludged to fix a bug in vpopmail library
	  which sometimes left extra character after the user name.
	- Login process crashed if master process didn't let some user login.
	  Normally this couldn't happen without error in configuration.
	- select() based I/O loop wasn't working so Dovecot didn't work in
	  eg. OSX. Also PAM authentication wasn't detected with OSX.
	- Didn't compile with NetBSD-current

v0.99.1 2002-11-25  Timo Sirainen <>

	+ Added doc/ script to easily generate yourself a self-signed
	  certificate. Modify doc/dovecot-openssl.cnf before running it.
	+ --with-ssldir configure option to specify default path for /etc/ssl
	+ Added ssl_disable setting to config file
	- OpenSSL wasn't checked properly by configure
	- vpopmail authentication module didn't compile
	- We should install the binaries into libexec dir, not lib
	- doc/configuration.txt and doc/mail-storages.txt were missing

v0.99.0 2002-11-24  Timo Sirainen <>

	+ Replaced hash file with binary tree file which makes Dovecot stay
	  fast with large mailboxes after expunging multiple mails.
	+ Several speed improvements with SEARCH
	+ SEARCH CHARSET support using iconv(), although case-insensitive
	  searching is currently supported only for ASCII characters.
	+ OpenSSL support.
	+ Support for regenerating Diffie Hellman and RSA parameters with
	  specified intervals. NOTE: currently doesn't work with OpenSSL.
	+ Support for each login connection being handled in it's own process.
	  This is the default as it's more safe especially with SSL.
	+ mbox locking is now safe, other processes can't modify the mbox file
	  while we're reading it.
	+ Notify clients with "EXISTS" almost immediately after new mail is
	+ Rawlog: Support for saving user connections into files - useful for
	+ Content-Language is finally parsed correctly
	+ Lots of smaller speed optimizations
	- Partial BODY[] fetches weren't working properly
	- BODY[section] was buggy with message/rfc822 MIME parts
	- STARTTLS wasn't working
	- \* flag was missing from PERMANENTFLAGS.
	- Comments inside <> mail addresses crashed.
	- imap-login printed UTC timestamps to logfiles
	- passwd-file wasn't reread the the file changed
	- PAM authentication was implemented wrong, which caused it to break
	  with some PAM plugins.
	- Lots of smaller fixes, mostly to do with reliability

v0.98.4 2002-10-06  Timo Sirainen <>

	* Just a final release before replacing hash file with a binary tree.

	- When fetching messages larger than 256k, sometimes Dovecot missed
	  to send CR causing corrupted data at end of message and possibly
	  complete failure depending on IMAP client.
	- Fetching BODY or BODYSTRUCTURE for message having content-type of
	  message/rfc822 didn't correctly add () around the envelope data.
	- Several fixes to make it compile with HP/UX ANSI C compiler.
	  Also fixed several warnings it showed up.

v0.98.3 2002-10-01  Timo Sirainen <>

	* Sorry, just noticed a very stupid bug which caused evolution 1.2
	  beta to crash. I always thought it was just evolution's fault :)
	- Several fields in BODY / BODYSTRUCTURE replies weren't quoted

v0.98.2 2002-09-30  Timo Sirainen <>

	+ --with-file-offset-size=32 can now be used to select 32bit file
	  offsets. Using them should be a bit faster and take a bit less
	  disk and memory (also needed to compile Dovecot successfully with
	+ maildir_copy_with_hardlinks option works now
	+ Check new mail and notify about it to client also after
	  commands which don't allow full syncing (FETCH, STORE, SEARCH).
	  Also always send RECENT after EXISTS notify.
	+ If we're out of disk space while opening mailbox, notify about it
	  with ALERT.
	- STORE and SEARCH didn't handle properly message sequence numbers
	  when some in the middle were externally deleted
	- SEARCH: Only first search condition was checked.
	- mbox: Message flags given to APPEND were ignored.
	- mbox: index was corrupted when changing flags for multipart MIME
	- Out of disk space-handling wasn't working properly with .customflags
	- if auth processes were killed, login processes weren't reconnecting
	  to them

v0.98.1 2002-09-24  Timo Sirainen <>

	+ Faster and safer mbox rewriting when flags are updated
	- Didn't save messages larger then 8192 bytes
	- Several mbox breakages

v0.98 2002-09-23  Timo Sirainen <>

	+ mbox support is finally working. There's still some reliability
	  fixes left but overall it should be quite usable.
	+ vpopmail authentication support
	+ We should be able to deal with "out of diskspace/quota" conditions
	  properly, by keeping the indexes in memory and allowing user to
	  delete mails to get more space.
	+ Several speed enhancements
	+ New configuration file option: overwrite_incompatible_index to force
	  using ".imap.index" file, overwriting it if it isn't compatible
	- Handle invalid message headers reliably
	- Tons of bugfixes and code cleanups everywhere

v0.97 2002-08-29  Timo Sirainen <>

	+ Large mails are handled in 256kB blocks, so mail size no longer
	  has hardly any effect on memory usage
	+ 64bit file offsets are used if supported by system. This means
	  Dovecot is fully capable of handling >2G mails in those systems.
	  With 32bit offsets >2G mails may not behave too well, but should
	  not crash either.
	+ I fixed lots of potential integer overflows. This should make us
	  fully crash-free no matter what happens (index file corruption
	  mostly). I didn't verify everything too carefully yet, so more
	  auditing is still needed before we fully reach that goal.
	+ Implemented several missing tasks / optimizations to index handling.
	  It should now stay fast after longer usage periods.
	+ New configuration file options: log_path, log_timestamp, imaps_listen
	+ "Critical errors" are now hidden from users, ie. any error message
	  that is not a direct reply to user error is written into log file
	  and user gets only "Internal error [timestamp]".
	+ Nonblocking SSL handshaking
	+ Lots of code cleanups
	- Lots of mbox fixes, it seems to be somewhat reliable now
	- Year in Date-field was parsed wrong
	- Appending mail to mbox didn't work right
	- Always verify that mailbox names are valid (especially they shouldn't
	  contain "../")

v0.96 2002-08-08  Timo Sirainen <>

	* Changed to LGPL v2.1 license

	+ STARTTLS support and optional disabling of plaintext authentication
	  (LOGINDISABLED capability)
	+ Support for custom message flags, each folder can have 26 different.
	+ New configuration file options: imap_listen, max_logging_users,
	+ You can specify config file location to imap-master with -c <path>
	+ All IMAP processes can now write to specified log file instead of
	  syslog. Either do this by setting IMAP_LOGFILE environment, or
	  give -l <path> parameter to imap-master.
	+ Some cleanups to remove warnings with BSDs
	+ Changed all %s .. strerror(errno) -> %m
	+ Rewritten memory pool code
	- imap-master didn't close all the fds for executed processes
	- iobuffer code was buggy and caused the connection to terminate
	- make install overwrote the existing dovecot.conf file, so it's now
	  named as dovecot-example.conf

v0.95 2002-07-31  Timo Sirainen <>

	+ Initial SSL support using GNU TLS, tested with v0.5.1.
	  TLS support is still missing.
	+ Digest-MD5 authentication method
	+ passwd-file authentication backend
	+ Code cleanups
	- Found several bugs from mempool and ioloop code, now we should
	  be stable? :)
	- A few corrections for long header field handling

v0.94 2002-07-29  Timo Sirainen <>

	* Supports running completely non-root now. imap-auth however is a
	  bit problematic as we don't support passwd-file yet.
	- Memory alignment fixes mostly
	- Other misc. bugfixes
