f11: Cannot add LDAP directory server to thunderbird-3.0b3

[Joachim Backes]

Hi,

I tried to add a LDAP directory server to thunderbird-3.0b3, but after 
having added the server by File->New->LDAP server in the address book 
window (general and advanced tab) and clicking OK, no ldap server has 
been added:

The server I tried to ADD IS:

Hostname: ldap.pca.dfn.de
     Base-DN: ou=DFN-PKI,o=DFN-Verein,c=de
     Port: 389
     searchfilter: (objectclass=*)

It seems, that I'm doing something wrong.

Any help is appreciated.

Regards
