Never mind. Saw your ldapsearch return 0 success. I would concentrate on ldap query to right OU, permissions (read permission is enough), etc.
# search result search: 2
result: 0 Success

My user is in the standard container (i.e. CN=Users) so I would think that sub would search there and find it? Perhaps that is my problem and either my base is incorrect or my scope is not correct? However, this seems to be correct according to the wiki (modules/Rlm_ldap). A final test with 'ldapsearch' yields similar results with no further information: [ ...

# numResponses: 2 # numReferences: 1 [ ... SNIP ... ] The only other thing I can think of is that the user that I'm binding to AD with to read information doesn't have the right permissions? But I would also think that the bind wouldn't be successful in the first place for the module if that were the case? I don't know what direction to take this in next to get more information. I would check the logs but since I'm running the server in debug mode the logs would just be duplicates of what I already have, correct? - List info/subscribe/unsubscribe?
