We are deploying thinclint networks with a broadband ISP . our server setup has a windows 2003 R2,TS,FS,Proxy and PDC and SUSE Linux running . TS will handle the session ,customer will be aunthenticated by ADS... now what we want is we also want our thin client users to be aunthenticated by BBRAS of ISP . may this question mostly on server part . However i also welcome any change in this strcuture including ciso elements. Now we are also planning for SESM ,3750,2950 to strenghtn the network ....If someone can tell me how the BBRAS authentication can be done using our thin clients would be fine ....else send docs on BBRAS setup
