On 4.1.x PAM, the following error occurs when trying to update a user who is a password view policy approver.
PAM-CMN-0155: User testuser was not updated.
Privileged Access Manager 4.1.x
Internal testing has narrowed the issue down to a user who is a PVP approver and inherits their Credential Manager Group from a User Group.
The issue with the code has been resolved as DE553877 in the 4.1.3 release.
