Hi Erinn

I originally asked the question as I was thinking my auth attempts were
failing when using ipa, however this was not the case.

On closer inspection, i found that the authentication was successful yet
dovecot was failing to read a "missing" mailbox.

I found that dovecot was simply missing the mailbox_location directive,
detailed below.

mail_location = mbox:~/mail:INBOX=/var/mail/%u

Once I restarted dovecot with this extra line, the authentication was
again validated. I was then prompted to accept the self-signed
certificate from dovecot and I was able to retrieve the mail as intended.

Does this help clear things up?


Dale
