[Dovecot] Can't get authentication for masterusers on Mac OS X Server 10.6.8

[Gilles Celli]

Hi dovecot masters,

This is my first post here, since I desperately need some advices from the dovecot community.
I've tried to get an answer on the Apple Forums but til now no luck....here we go:

I've tried to sync our users emails (Mac OS X Server 10.6.8 Snow Leopard with dovecot 1.1.20-apple0.5) via imapsync
to our new server by using the masterusers authentication method on the old 10.6.8 server...

The main problem on OS X Server 10.6.8 is that dovecot 1.1.20 uses the OD (OpenDirectory) driver (well I think),
so that when following the directions of Master users/password from this page I can't login with the
http://wiki1.dovecot.org/Authentication/MasterUsers

I couldn't find anything on the OD driver directive....the dovecot 1.1.20-apple build doesn't even have the shadow driver built in (see below the dovecot --build-options),
so that passdb shadow {} won't work anyway


I always get NO Authentication failed, when trying the following:
>telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK Dovecot ready.
1 login user1*mailadmin PASSWORD
1 NO Authentication failed.
 
I've tried also to add a Post-login scripting like described here, but no luck either:

Does someone know how to fix my migration issue ?

Any help is greatly appreciated.

Gilles

Here's my dovecot :

>dovecotd --build-options
Build options: ioloop=kqueue notify=kqueue ipv6 openssl
Mail storages: maildir mbox dbox cydir raw
SQL drivers:
Passdb: checkpassword od pam passwd passwd-file
Userdb: od passwd passwd-file prefetch static


Here's my dovecot -n output:

>dovecotd -n
