Problem

-- When using the mixed domain option, the customer cannot retrieve any users or all users, however, the LDAP, ActiveDirectory filters are defined correctly

Resolution

1. Go to the Identity store you defined, in the User mapping section
2. The fields loginAttributeName and lastnameAttributename must point to a valid value defined in the LDAP for all the users. If the value do not exist for a user, during the synchronization, you will not retrieve the user.

3. The others attributes (but the filter) in the UserMapping section can point to something not defined in LDAP or not used by all users, you we still be able to get the users in Passport during the synchronization.

4. You can use the free software Apache Directory Studio to connect to your LDAP and check for the values to set for the UserMapping attributes.
