CA Privileged Access Manager (PAM)

Issue/Introduction

We are not able to login to CAPAM app and it keeps on asking for credentials.

After 4 to 5 attempts it logs in and shows only blank screen.

Cause

The PAM client was installed on one Windows server, and an application launcher was configured for all users to launch this one PAM client. This is not supported by the current PAM client installation, which uses lock files and cache folders in the PAM client installation folder, not in individual user's AppData or TEMP folder. The PAM client log shows errors like:

Environment

Release : 3.4

Component : PRIVILEGED ACCESS MANAGEMENT DOCUMENTATION

Resolution

If you want to use shared PAM client installations rather than have each PAM user install their own client, please make sure that your configuration adheres to the requirement of one concurrent user per PAM client. As of April 2021 this is not clearly stated in online PAM documentation yet, but a request has been submitted to add such a statement.
