A new externalIdentity flag was added to the sas.logon.groups configuration to support the SUB::SAS.ExternalIdentity substitution parameter for row-level security in SAS^® Cloud Analytic Services (CAS) in SAS^® Viya^® 3.5.

However, activating this flag can cause failures when you launch a compute session that uses Kerberos constrained delegation.

The workaround is to disable this flag.
