Technical Tip: RADIUS user credential verification via GUI/web interface
Description
This article describes how to verify Radius server user credentials via the GUI/web interface of the FortiGate.
Scope
FortiGate.
Solution
Before FortiOS 6.0.0, it was only possible to check the Radius user credentials via CLI.
However, starting from FortiOS 6.0.0 and onward, this feature is available on the GUI as well.
To check the Radius server user credentials, go to User & Device -> Radius servers
Edit the configured Radius Server and click on the 'Test User Credentials' button.
Note: Before testing user credentials, make sure that the Radius Server is already configured and there is no connectivity issues between the FortiGate and Radius Server.
After that, enter the username and password of the user.
After that, enter the username and password of the user.
As it is shown on the above screenshot, the FortiGate can check 'Connection status' and 'User credentials' and, upon successfully authenticating, it shows additional information such as Radius 'AVP' and 'VSA'.
Note: Until FortiOS 6.2.6 and FortiOS 6.4.2, the Radius server user credentials check via GUI/web interface works only with the PAP (Password authentication protocol) scheme. This behavior is fixed in later versions of FortiOS.

If the user credentials is tested with a Radius Server that does not have 'PAP' enabled, the FortiGate will show an 'Invalid credentials' message:
When using FortiOS 6.0 or earlier versions than 6.2.6/6.4.2, for all schemes other than 'PAP', it is recommended to test it via the CLI:
diagnose test authserver radius
<server_name> <chap | pap | mschap | mschap2> <username> <password>
For example:
diagnose test authserver radius WIN16 mschap2 radiususer1 password
authenticate 'radiususer1' against 'mschap2' succeeded, server=primary assigned_rad_session_id=457812022 session_timeout=0 secs idle_timeout=0 secs!
