I'm guessing that it is breaking my specific method of authentication.

Works great with all the beta versions. I installed RC1 and get massive authentication failures.

auth_debug_passwords = yes auth_master_user_separator=*

auth default_with_listener { mechanisms = plain

passdb passwd-file { # Master users that can log in as anyone args = /etc/dovecot.masterusers master = yes #pass =yes }

passdb passwd-file { # Path for passwd-file args = /etc/vmail/shadow.%d }

userdb passwd-file { # Path for passwd-file args = /etc/vmail/passwd.%d }

socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } }

}

It seems to be using wrong dovecot.conf file. Above there's no PAM configured, but here it's using PAM.

Right - hmmmmm - so why would it be using the wrong one? The one I want it to use is /etc/dovecot.conf. Is there another default?

OK - I just tried it again and here's what I got. Switching back to beta 9 fixes it so whatever you changed it started in rc1.

Well, I guess it's these. -1 really is invalid and I think it practically means that the process would get root's GID, which really isn't a good idea.

I'll add some extra checks to make sure this can't be done with other userdbs either..

Hmm. Actually with me it gives this:

dovecot: Jul 01 22:36:11 Fatal: setegid(4294967295) failed: Invalid argument

Also looking more closely your log it looks like you're not using those files as userdb either. So, fixed:

http://dovecot.org/list/dovecot-cvs/2006-July/006017.html

Just upgraded to RC2 and this problem is fixed. Good job!
