Hi List,
I have a problem with auth for just one user:
dovecot: Sep 30 09:56:16 Info: auth(default): new auth connection: pid=3809 dovecot: Sep 30 09:56:17 Info: auth(default): client in: AUTH 1
PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1
resp=AGoucnVpc0BtZXJreC12ZXJrZXJrLm5sAGJsb2VtMDEh
Note that the user's password is visible in the above resp text if you base64 decode it. Might want to change it. :)
How can I determine why pam_authenticate() failed?
Maybe look at PAM logs to see if they say anything? Unfortunately PAM's logging is pretty horrible and there's nothing Dovecot can do about it. See what modules /etc/pam.d/dovecot has enabled and maybe one of them prevents access? Although the most typical reason for auth failure is simply that the user typed the password wrong..
