[RADIATOR] Radiator/TACACS+ via ADSI

Wed Nov 9 09:58:40 CST 2011

Hi Heikki,
Yes, I have checked the privileges.
So, this time, I ran the radiator from the services.msc which starts with local system account instead of command line. 
It looked like it is working in a way, but I got following error:

Wed Nov  9 10:49:10 2011: DEBUG: Handling with Radius::AuthLSA: LSA

The id, stevekim, is a member of networking_staff of ad group.

Thanks,

Steve.

The Domain here is a valid Windows domain?

Also, the reference manual ref.pdf lists a couple of requirements (Win32-LSA ppm, need for special privileges for user Radiator runs as on the Windows server and access rights for the users that try to authenticate).

Have you noticed and checked these?

If there are further problems, full log file from the moment Radiator starts would be useful to see.

Thanks!
