LDAP issue

Hi,

i try to configure LDAP authentication. I am able to search for users in the
Teaming Navigator. But the users can not log in. "Enter valid data" But the
password is correct.

If i create a local user it works.

eDir is 8.8
LDAP attribute that identifies the user is uid.
Searchfilter is (cn=@screen_name@)

Any hints are welcome

TiA

Bernd
