Hi ShawnC,

If you use the “direct” option, communication will be through management.

If you use the “pool” option, it will be through TMM and self IPs will be used.

If self IP is not defined for the VLAN where the LDAP servers are located, and there is no TMM route, you can route the traffic from a different self IP.

I configured a route domain, and I am unsure if that is affecting the issue. The VLAN responsible for authentication has a self-IP configured, but it does not have a floating IP.

      The problem was that the interface I was trying to access didn't have a floating IP configured, only a self IP. After configuring the floating IP, it worked.

      Finally, using Route domain 1 with a floating IP configured successfully verified the connection.

      Thank you for your help.
