I have a client wanting to do WEB Authentication using Radius with MS IAS. Initial Authentication to Web (Level 1) works fine, but when trying to modify some settings (Click Network Interfaces -> Fast Ethernet) the Login Prompt reappears stating "Level 15 access" is required. Any further Authentication fails. IAS states Auth Request OK and accepted, Service-Type in Response is set to "Login". "deb radius" brings "RADIUS/DECODE(00000000): There is no RADIUS DB Some Radius attributes may not be stored".
AP is running 12.3(8)JA Software.
AP is running default config except Radius WEB Login (ip http authen aaa etc.)
