I got it to work! I'll explain how in case anyone else is interested:
First, the documentation is wrong about the username format. The config
file documentation said <username><separator><master
username>, but I had
to reverse that to <master username><separator><username>.
Second, I had some extra passdb lines that worked before, but once I
turned on master=yes, they broke Dovecot. Before, right after my LDAP
passdb line, I had:
passdb passwd {
}
passdb shadow {
}
userdb passwd (
}
...because I wanted to first check LDAP, and if a user wasn't found, check
the local system users as well. But I think the problem was I have the
system setup to use LDAP nameservices as well, so maybe it was complaining
about me having two LDAP queries? I don't know. It used to work fine
until I threw in the master user option. So, I replaced the above with:
passdb passwd-file {
args = /etc/shadow
}
userdb passwd-file {
args = /etc/passwd
}
...and everything worked. That's probably better anyway. The above still
loads my local user accounts, after first checking LDAP, and allows master
users.
# telnet localhost imap
