dovecot - Mar 2008 - 1.1 master auth not expanding static userdb variables

Can dovecot-1.1 deliver work with static userdb?  I'm currently running 
dovecot-1.0.12 and postfix-2.4.6, with virtual users' maildirs all owned 
by vmail and mail_location = maildir:/var/mail/%Lu.  The following 
definition of the dovecot transport in postfix/master.conf works fine with 
dovecot-1.0:

dovecot         unix    -       n       n       -       1       pipe
      flags=DRh user=vmail:vmail argv=/usr/libexec/dovecot/deliver \
      -d ${user}@${nexthop} -n -m ${extension}

Note that I'm not using postfix pipe's "u" flag, since that
lowercases
everything to the left of "@", including the extension, and we need
the
extension to be case sensitive.  Dovecot is configured with static userdb 
and args = user=%Lu uid=206 gid=206 home=/var/mailhomes/%Lu, which takes 
care of making sure the username is lowercase.  All of this has been 
working fine for some time with dovecot-1.0.

After upgrading to 1.1_rc2, however, deliver creates a maildir named
"%Lu"
and delivers all mail for all users to it.  Everything else works just 
fine as before:  users can log in, postfix can auth smtp via dovecot sasl, 
etc.

I've tried invoking deliver with -k, adding
"mail=maildir:/var/mail/%Lu"
to the end of the userdb args, and checked file permissions on the auth 
sockets, maildirs, and virtual homes.  Rolling back to 1.0.12 is the only 
way I can get deliver to behave as expected.

What changed between 1.0 and 1.1 in the way deliver does userdb 
lookups or how dovecot auth serves  to it that could cause 
this?  Does anyone here here have a similar config working with 1.1?  Has 
anyone else observed similar behavior?

Thanks,
Andrew

I think you need this patch,

http://hg.dovecot.org/dovecot-1.1/rev/631fd6f25e41

which was mentioned in an unrelated thread earlier today. I also 
struggled for some time until I realized this. Hopefully rc3 will be out 
quickly :-)


HTH,
Anders.

Is the %Lu from home=/var/mailhomes/%Lu user from user=%Lu? Do either of
them get expanded correctly? dovecot-auth should already do the %Lu
expansion, not deliver/master. Set auth_debug=yes and see what it shows
in "Master out" line?

I couldn't reproduce this, %Lu was always expanded. I did find a crash
though: http://hg.dovecot.org/dovecot-1.1/rev/2d3b9a6d23f5

It looks like dovecot-auth is doing the right thing.
