Using rpms and converted dovecot.conf with doveconf. Need assistance to
determine how to resolve 'auth-worker' and userdb complaint.
logging into mysql from commandline with mail admin acct and using
dovecot sql query is successful but the following fails:
doveadm auth -x service=imap -x lip=127.0.0.1 john
Password:
passdb: john auth failed
extra fields:
temp
doveadm(root): Fatal: Couldn't connect to auth socket
sudo /usr/libexec/dovecot/imap -u john
Error: userdb lookup(john): Disconnected unexpectedly
Fatal: Internal error occurred. Refer to server log for more
information.
sudo /usr/libexec/dovecot/imap -u john at homenet.lan
Error: userdb lookup(john at homenet.lan): Disconnected unexpectedly
Fatal: Internal error occurred. Refer to server log for more
information.
