Dovecot Virtual domain/passwd-file login issue

Question

I used this walk through http://wiki2.dovecot.org/HowTo/VirtualUserFlatFilesPostfix but there is still an issue not allowing me to login.

/var/log/dovecot.log

Jan 13 10:25:49 imap-login: Info: Disconnected (auth failed, 1 attempts): user=<[email protected]>, method=PLAIN, rip=10.180.34.84, lip=10.180.33.42
Jan 13 10:49:14 imap-login: Info: Disconnected (auth failed, 2 attempts): user=<[email protected]>, method=PLAIN, rip=10.180.34.84, lip=10.180.33.42

I have disabled selinux and debuggin is enabled but still not able to get logged in

there was an issue with the guide to use the user doveauth which does not exist so i switched that to use dovecot user.
