Hello,

After going crazy building a dovecot cluster, I finally see the light ;-)) But some things are "strange" and could probably be fixed/enhanced.

First : I follow the wiki doc, setting global doveadm_port. Things did not work, I've got:

dovecot: doveadm(X1234567): Error: sync: /var/run/dovecot/auth-userdb: Configured passdbs don't support crentials lookups (to see if user is proxied, because doveadm_port is set)

Same kind of error too when trying to use doveadm on the command line to get the replica status. My user/auth db is LDAP with "auth_bind = yes", but I don't understand the message in these context and did'nt know how to fix this. I tried to hardcode proxy/proxy_maybe property in the passdb declaration etc... Finally, I remove the global "doveadm_port 12345" and add ":12345" at the end of my "mail_replica =" line and all began to work ! Is it a wanted and expected error/fix ?

Ok, this first point should be fixed by http://hg.dovecot.org/dovecot-2.2/rev/a2e0e89bc27d Need to test it.

Thank you. Emmanuel.

Secondly: Now all is working and "doveadm replicator status '*' " correctly list all my users and the status, but after a few seconds (after replication kick in), I see all user listed twice. One time, as declared in the userdb with letters in uppercase : "X1234567" One time, in lowercase : "x1234567" On disk, all is OK, with only one replica in an uppercase directory. I initially think that it was a mismatch between userdb and passdb users return, but it was in fact the default value of auth_username_format that was the culprit. After going from the default %Lu to %u doveadm replicator status show only one entry per user as expected. Is it wanted and expected too? why auth_username_format is used/interact with/in the replication process and/or the replicator status command ?

Not all is functionally tested, I go back to work. My is conf at the end of this message.

Thanks Simo for this great piece of software.

Emmanuel
