I try to authenticate the mars with the ACS but do not have any message only that the authenticacions is failed.
Let me tell you everuthing i did:
1. I created a client RADIUS in the ACS for MARS.
2. I configured in ADMIN> Authentication Configuration > AAA Server: the config of ACS Solution Engine and when i tried to prode the connectivity appear a message that say "Connection to AAA Server succeeded" but in the bottom appear a box with the following information:
Input username and password to check authentication: i write the information but when i logout an try to log again with the username the AUTHENTICATION FAILS.
So i do not know which could be the problem, because i configure the mars into AAA Server like a client just said the guide config of MARS.
