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:$6$<salt>$<password>:15006:0:99999:7:::

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

Regards, Pascal 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.
