[Serusers] doubt with serweb + radius authentication + serctl add

hello friends, 1)i want to know what is the extra facilities which we get if we use the subscription to the ser (i.e with serctl add or serweb giveng the access to the users). i am using the free radius authentication and its working fine for me. 2)can we use the database to the free radius server rather than just appending the username , password in the file of users in free radius server. 3)can we put the inter relation betwen the radius and the subscribe table of the ser so that we need not manually enter the details into the users file as and when i need to add the users to the ser system. __________________________________ Do you Yahoo!?
