Cisco RADIUS Authentication w/ Active Directory and Network Policy Server


I'll try to keep this short and sweet. It took me a bit to find the exact commands I used. The configuration below has been validated to work on Cisco routers, switches, and voice gateways.

Part 1. RADIUS Server Configuration

Assuming you already have a Network Policy Server installed on a DC somewhere...

RADIUS Clients and Servers > RADIUS Clients > Right Click > New RADIUS Client
  • Add Friendly Name
  • IP
  • Vendor = Cisco
  • Shared Secret
    • Manual
    • Enter a key (same as used on the cisco device)
Policies > Network Policies > Right Click > New (use defaults unless specified)
  • Policy Name (I just called this the same as the client friendly name)
  • Conditions
    • Windows Groups: AD Group with network administrator accounts
    • Client Friendly Name: same as friendly from "RADIUS Clients" (prevents policies from inadvertently being applied to the wrong devices. Optional precaution)
  • Authentication Methods > Check "Unencrypted authentication"
  • "Configure Settings"
    • RADIUS Attributes
      • Standard > Remove Framed-Protocol PPP
      • Vendor Specific > Add (allows user to launch in to enable mode by default)
        • Vendor = Cisco
        • Attribute Name = Cisco-AV-Pair
        • Value = shell:priv-lvl=15

Part 2: SSH to Cisco Switch/Router

You'll need...
  • VLAN/IP that authentication will originate from
  • IP of your RADIUS Server
  • RADIUS Secret used in part 1.
Run the following from the command line... ​conf t
aaa new-model
aaa authentication login default group radius local
aaa authorization exec default group radius local
ip radius source-interface <<VLAN/IP>> Interface (e.g. Vlan1 or GigabitEthernet0/0)
radius-server host <<IP of RADIUS Server>> auth-port 1645 acct-port 1646
radius-server key <<RADIUS SECRET>>
service password-encryption

Part 3: Testing

  1. Ensure your admin account can log in
  2. Ensure that other accounts cannot log in. Especially if you have other RADIUS auth policies like we did.
  3. Validate that your local account no longer works by default.
  4. "Disable" your RADIUS client. Validate that your local account works as a fail safe.

Grant Access to Specific Runbooks in Orchestrator

Since I had a hard time finding a clear guide on the topic here goes...

As a systems administrator / domain admin I typically have access to just about any system. As such, no big deal for me to be in the "users" group recommended for the initial Orchestrator install. This group is a bit of a misnomer. These are your designers. So in my case I have a group called “app-scorch-users” which consists for systems administrators.

So the issue is, how to provide runbooks specific to other roles. I want my DBA, developers, and so on to be able to execute their runbooks from the web console with ease but only those we choose. i.e. DBAs can’t run developers runbooks.

  • I started by creating a domain group: app-scorch-operators. Anyone who will run (not design) runbooks will go in this group.
  • Add that group to the root Runbooks container (right click > permissions)
  • Restrict its access to "read"
  • Go to Advanced > Select the group > change "Applies to:" to "This object only"

The purpose of the operators group is simply to grant access to read objects under the “Runbooks” node in the connections pane.


 
This opens up the ability to assign perms to users/group on the subfolders or directly to runbooks. In this example, I am attempting to grant several individuals to a folder (you could create domain groups per folder too).

  • So I'll go to the "Patching" folder > Right click > Permissions
  • Add any users or groups you'd like to execute runbooks with ONLY Read




  • Once added, you'll need to add one more thing…."Publish". Otherwise you'll get an error stating the user must have publish to run a runbook.
  • Go to Advanced > Edit > "Show advanced permissions"
  • Read properties and list contents will already be checked.



Now when your "Operators" go to the web Orchestrator Console they'll only see the folders where they were granted read/publish. (note below SC2012 Solutions from the first screenshot is not displayed)
