I would like use W2k8 as Radius Server for login authentication for AlliedTelesis switches (x900-12XT/S). I configured one switch as client: ! ... ! ssh server allow-users ra* ! ... ! radius-server host 10.20.4.50 key makaron aaa group server radius GRUPCIA server 10.20.4.50 ! aaa authentication login default local group GRUPCIA ! and second switch as server: ! ... ! crypto pki trustpoint local ! crypto pki enroll local radius-server local server enable nas 10.20.4.50 key makaron nas 10.20.4.70 key makaron group login1 attribute Cisco-AVPair shell:priv-lvl=1 attribute Service-Type Login-User group login15 attribute Service-Type Administrative-User user rajacek password ramkmk group login15 user rakamil password raokok group login15 user ramotyl password rartrt group login1 ! It works. Now I would like move Radius server from x900 to W2k8. I don't know how I should configured W2k8. I try use the same setting like for CISCO devices, but it does not work: filedb.experts-exchange.com/incoming/2008/12_w51/87700/TA0001-Windows-2008-RADIUS-for-C.pdf How should I configure W2k8???
