OK, that explains why I couldn't reprodue it easily. Although I'm still not sure why it would happen sometimes and not other times.

Do you only have one domain? Maybe easiest would be to set auth_default_realm to that.

This is passdb configuration as a userdb, so it doesn't really work. Except directors don't use userdb, so it doesn't really break either.

You had:
pass_attrs = mail=user,userpassword=password

This should have changed the username always to same as "mail" field, which should standardize the usernames with director also.
