Hi community,


i´m trying to setup the USS in our 14.1 AA configuration with CA Service Catalog and SDM. I managed to get the USS running whit EEM authentication. In our EEM we have multiple LDAP´s as User Store defined. One LDAP has the default Attribute Mapping "Microsoft Active Directory" which is using the sAMAccountName for "User name". Another LDAP has a customized mapping where the userPrincipalName is used for the "User Name".



- sAMAccountName

- User Name in EEM (example): Name1



- userPrincipalName

- User Name in EEM (example):


The problem is, that i´m only able to login to USS with users of Domain1 with "Name1" as Username in the USS login screen. If i enter "" as username i get a "UserScreenNameException" error message. Authentication is set to "By Screen Name" in USS. I also set the "bypass.liferay.screenname.validation=true" value in the


The question is why the userPrincipalName can not be used and whats happening if i have two different domains with sAMAccountName mapping in EEM and there are a user John.Doe in each domain?

I hope the problem is explained properly and someone has the crucial information for me.


Feel free to ask for more information!


NOTE: I don´t know how important this is at this point, but the users of the different domains in EEM are also in the MDB in different tenants:

          -     Domain1 = Tenant1, userid in MDB like "domain1\Name1"

          -     Domain2 = Tenant2. userid in MDB like ""
