In PAM 3.1.1 and 3.2, when filtering policies using 'User(Group)' column and specifying a user for the value, only policies specifically defined for that user are returned. Policies defined for a group in which the user is a member of are not returned.
This behavior is also observed when selecting 'Manage Policy' from a user under Users > Manage Users.
For PAM 3.1.1 the fix for this has been included in 3.1.2 (DE342881):
For PAM 3.2, the fix for this will be included in upcoming maintenance release 3.2.2.
