Getting "PAM-UI-1003: Unauthorized" error on PAM GUI.
Privileged Access Manager, all versions
PAM uses PHPSESSID cookie for session management.
PAM User's PHPSESSID cookie value gets stored in an internal mysql table which will display user session at "Sessions -> Manage Sessions".
When a user session gets timed out or logout, the record will be removed.
If a request is received with a PHPSESSID cookie that is not present in the table then this error will be displayed.
User session has been terminated or did not exist.
Ideally the "Timeout Warning" and "PAM-CMN-009: Your login has timed out." window should popup but this is not always the case.
PAM User simply need to re-login as previous session has been terminated.
