configuration Radius acs with cisco FMC

[Hacen.bani]

hello,

i have configured my FMC v6 with acs 5.8 in Radius for management 

all configuration is fine and i can access on FMC by users created in ACS

but after the configuration the admin local account of the FMC stay always fonctionaly 

i think this users should run if the ACS is down 

i need solution to make this local users not fonctionnaly if the acs is UP and fonctionnaly if the the ACS is Down 

thank

here is the FMC works for the user authentication.

• internal authentication — The system checks the list in the local database for the user.

• external authentication — The system checks the list in the local database for the user and, if the user is not present on that list, queries an external authentication server for its user list.

If you have same username available locally, that prefer local, so delete all the local users except admin. so all authentication go to ACS.
