[Dovecot] LDAP auth_bind fails

[Pol Bettinger]

Hello,

I wanted to configure dovecot for using auth_bind but didn't succeed to 
me it seems like it does always an anonymous bind.

Dovecot version 2.1.1 (I started with 2.1.0 and hoped 2.1.1 would fix it)

I tried to play around with the base, pass_attrs,pass_filter to no avail 
but didn't succeed.

Looking at a wireshark trace i only saw 7 packets and it seemed to me 
dovecot did only an anonymous bind.

any help would appreciated

Sincerely
Pol Bettinger
