[Dovecot] Cannot authenticate with new Red Hat/Fedora SHA512

[John Cooper]

RHEL6 and Fedora 14 use an improved password algorithm of SHA512 on a 
brand new install of the OS (:$6$ in shadow file).


cat /etc/shadow
user1:$6$$:15006:0:9:7:::

I cannot get dovecot to authenticate. I've search for a way to change 
the default algorithm in dovecot and found you should use CRYPT but I 
don't know what to put in the /etc/dovecot/dovecot.conf or 
/etc/dovecot/conf.d/*


Can this be done or do you need to use an alternate password file with MD5?

Thanks, John.

You forgot to show your `doveconf -n` output.

Hm, looks good so far. What was logged to your maillog?
You may also set auth_verbose = yes in your conf.d/10-logging.conf

Looking in secure.log as authentication error, didn't get to maillog. 
maillog had error :-


dovecot: imap(usser1): Error: user user1: Initialization failed: 
mail_location not set and autodetection failed:

 Mail storage autodetection failed with home=/home/user1

So added this to dovecot.conf

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

Restarted dovecot and everything now works.

Thanks, John.
