Maybe you have enabled some PAM plugin that denies the user's access even if the password is correct. Unfortunately there's no way to enable debugging for PAM. Try simplifying your PAM setup, or if you can't figure out anything else switch to passdb shadow.
SOLVED: Should anyone else run into this and debugging shows no issues, just random dovecot logins fails - there was a bad username stored. "pwck" showed it up.

I'm not getting a hit on "Dovecot pwck". Can you elaborate. ? Original Message ?
