Is there a reason why you are using port 390 rather than 389? What is the actual error you are getting?

I'm new with LDAP and now I have to configurate phpBB 3.0.4 for LDAP authentication in Windows OS. In the same machine I set LDAP server using ADAM, with the following: - a user having username 'admin' and the password 'mypassword' - the group 'forum', containing the same user 'admin' In phpBB (with phpinfo), LDAP module is correctly loaded. In phpBB authentication panel I set the following: authentication: LDAP LDAP server name: ldap://localhost:390 porta del server LDAP: (not specified) dn base LDAP: CN=forum,CN=users,DC=mycompany,DC=int uid LDAP: uid username filtering LDAP: (not specified) attributo e-mail LDAP: (not specified) LDAP dn user: admin password LDAP: mypassword but phpBB is not able to connect with that user/password. What's wrong? Thanks to all!
