Windows 2008 and 2012 are embedded with NPS, which can be used as a RADIUS server,
Parameters are similar to Freeradius, with few guides and few documents
The next major record is
NPS provides Telnet authentication service for CISCO&H3C
IPSec user authentication (test, gradual completion)
The Network Policy and Access Services include the following role Services:network Policy Server (NPS) Health registration Authority (HRA) Host credential Authorization Protocol (HCAP) RADIUS Server and Proxy
Windows NPS for CISCO telnet authentication
Refer to this post specifically
Cisco IOS Radius authentication with Windows Server, NPS
The key is this paragraph:
Next you'll need to add a Vendor specific Attribute by clicking on "Vendor specific" under the left side settings and CL Icking The Add ... button
Scroll down the list and select "Cisco-av-pair" and click Add. You'll be prompted to add the Attribute information, where you'll click Add ... and set the Attribute value as shell:priv- Lvl=15
This specifies which privilege level was returned to the authenticating User/device after successful authentication. For Network Engineers This would is shell:priv-lvl=15 and the Network support technicians would use shell:priv-lvl=1
2. Freeradius for H3C/HP Comware 7 telnet authentication
Refer to this document for details
Freeradius AAA Comware 7
The parameters are basically the same, the only difference is the way the shell is written,
e.g.
Shell:roles=\ "Nework-operator\"
3. Using Windows Server as a RADIUS Server for a Cisco ASA
Windows 2008 under NPS and Windows 2012 are similar, you can refer to the following
