Hello!
This bug exists in 2.1.26 , and, I guess , in previous versions.
Problem is that after user is authentificated with ldap bind , ldap
connection for checking user in group ( lak_group_member function )
is made with this user's bind, not bind parameters from config file.
User can not ( and have not in our case- I don't know why , but this is
not real problem ) have access to ldap groups.
And so, authentication is always fail.
I added unbind and anonymous bind ( enough in our case):
You have a major flaw in your directory server's access control configuration,
if it has granted anonymous binds more privileges than authenticated binds.
No proper security system would ever do such a thing. Fix your access control
configuration. This patch is wrong.

Could you, please, fix this bug correctly?
Thank you!
