I'm working on SEPM 12.1.5 and LAN Enforcer version 12.1.4013... I try to add a new RADIUS Server Group on the SEP Manager but it fails, it shows "Server Security Validaton Failed" on the log at the bottom of the Admin/Servers Tab.
The LAN Enforcer is a client on the clients.conf of the RADIUS server and the secret password is the same.
I don't know what else to do.
This RADIUS is working perfectly on another SEPM and others LAN Enforcers.
Hope you can help me.
Apparently already solved the problem, using this post: https://www-secure.symantec.com/connect/forums/sepm-security-breach
We have to do the procedure with a SEPM administrator account.
