Failed to authentication and join domain to WSA using F5 VIP

Hi,

So our setup is:

VIP1: 1.1.1.1

Port: 389

Profile: Standard setup - TCP

Pool: WSA server port 389 tcp

VIP2: 1.1.1.1

Port: 389

Profile: Performance Layer 4 - UDP

Pool: WSA server port 389 udp

We are trying to load balance WSA but the issue is that we encountering issue - failed authentication and cannot join domain

Any tips we can try on how to solve this issue?
