I have a situation, when a user can login to USS for the first time with the user and the DA password can be accessed successfully, but when the user changes the password in DA and tries to log in to USS they can not connect. Authentication has failed. Try again. But if I change the user's password in the control panel and assigned whit the same password of DA the user can login.
other situation happends with the old users when they change the password on DA, after that they can´t login on USS.
the user's password on USS synchronize whit the DA ? CA EEM is installed and configured on CA USS.
The described behavior matches with the one noted in the following document:
Users are unable to log into Unified Self Service - CA Knowledge
