LDAP lookups are case-insensitive. Unless you somehow normalize the
username, it's possible that a user logging in as "user", "User" and
"uSer" are treated differently. The easiest way to handle this is to
tell Dovecot to change the username to the same case as it's in the LDAP
database. You can do this by returning "user" field in the pass_attrs,
as shown in the above example.
If you can't normalize the username in LDAP, you can alternatively
lowercase the username in dovecot.conf:
auth_username_format = %Lu"
This really should be the default...
