Hello,

I have radius authentication on SBC:

type radius
protocol pap
tacacs-authentication-only disabled
tacacs-authorization enabled
tacacs-authorization-arg-mode disabled
tacacs-accounting enabled
server-assigned-privilege disabled

login-as-admin enabled
management-strategy hunt
ike-radius-params-name
management-servers x.x.x.x

address x.x.x.x
port 1812
state enabled
secret ********
nas-id
realm-id
retry-limit 3
retry-time 5
maximum-sessions 255
class primary

authentication-methods all

And when I'm using my LDAP account I have an admin access.

After the activation of Admin Security I can only access as user:
