Hi, As of 9.4M2 an authentication domain can be labeled as Outbound Only. That would lift the uniqueness constraint. From the docs (SAS(R) 9.4 Intelligence Platform: Security Administration Guide, Second Edition😞 Outbound and Trusted Authentication Domains Beginning in the second maintenance release for SAS 9.4 is support for outbound and trusted authentication domains. A login in an outbound domain is used only to provide SAS applications with seamless access to external resources, such as a third-party vendor database. These logins are not part of the SAS identity phase, which attempts to determine the current metadata user by matching their authenticated user ID to the user ID stored in a login. Therefore, for outbound domain logins, the uniqueness requirement on the user ID is not enforced. Regards Jan
