The error: "[LGN0022]Person-only not supported when gace flag is off" relates to functionality which is not fully live yet on SF side.


The error appears to be caused by the inclusion of the parameters "person_only" and "person_guid" in the authentication process.

As a solution, please remove the "user_uuid" attribute from the IAS side.
