PAM-CMN-0900: Bad User ID or Password

Environment

Release : 4.x

Component : Privileged Access Management

Cause

Resolution

Issue was caused by a new F5 load balancer which was not fully onboarded which was showing no traffic and had references to some old IPs.  Once network team resolved that issue and properly onboarded the F5 Load balancer they were able to login properly.
