After going through your log file,I think you ldap is working fine. Did you try logging in using an AD account to SM. Suppose you have an AD user called '\shreesha' with AD password. Now in SM, try creating an operator with the name 'shreesha' , (don't give any password while creating the operator in SM) and then, try logging in to SM using the login 'shreesha' and give AD password, while logging into SM. If you log in successfully, then your ldap works fine, cos' it is logging in using ldap password.
