After installing seos and unab appears some local accounts

• CA Privileged Access Manager - Server Control (PAMSC)

Issue/Introduction

When installing seos and unab 

These local accounts appeared on the machine:

ac_<user>:x:949895:1:UNAB tmp user:/tmp/mcy:/bin/sh
...

Environment

CAeAC-1410-50.114.x86_64
uxauth-1410.50-114.x86_64

Resolution

ac_xxx  accounts are temporary accounts that are created during UNAB installation for checking correctness of PAM configuration after we introduce our PAM module (pam_uxauth).   Such temporary accounts are deleted now, so those they see must be from older UNAB installations and can be deleted, e.g.,   userdel  ac_iafnv

a password those accounts use is a long computer-generated string that is never recorded anywhere, so once such account is used for checking PAM configuration, it was impossible to reuse/exploit it.
