Introduction
On Threat Grid Appliance between version 2.12.0.1 - 2.12.2, a bug was introduced which breaks the Radius authentication support.
A permanent fix will be available in next software release.
This article will discuss the short-time workaround, which is valid until next reboot. This workaround is possible to apply if the user has access to Opadmin portal (assuming Authentication was configured to use either Radius or System Authentication)
If the user does not have access to Opadmin, please create a TAC case to troubleshoot the issue.
Problem
After upgrading to between 2.12.0.1 - 2.12.2, Radius authentication doesn’t work for both Opadmin and Clean interface portal.
Solution
In appliance 2.12.1, support is added for "signed commands" -- JSON documents which, when fed to opadmin (Support > Execute Command), run specific commands as root.
Using signed command we can implement a workaround for this bug until next reboot. [ This bug is fixed in 2.12.3]
Procedure
As first step Reboot the appliance.
Then follow below instructions -
Using Opadmin Portal:
- Login to Opadmin portal using system authentication method, browse to Support > Execute Command
- Copy following command and execute it:

Using CONSOLE:
If the user has access to Applinace Console (TGSH), above signed command can be executed from console -
Log in to appliance console (opadmin interface), select `CONSOLE`
Threat Grid Appliance Console
Run command `graphql` to start GraphQL interface
GraphQL interface
Copy following command and paste in graphql interface. Press Enter -
