"Temporary authentication failure" ? Cant connect with ldap user

[David Scheele]

@Steffen Kaiser:
Sorry I wrote that wrong. I did indeed *grep -v '^ *\(#.*\)\?$'
dovecot-ldap.conf.ext* to get those results.

@Bob Miller:
And how would that look like? I added a auth_bind_userdn looking like this:
*auth_bind_userdn = uid=%u,dc=[hostname],o=de*
And restartet dovecot, no use.

Any other ideas?

Best,
David
