Hi,

we wanted to set-up SAML-Auth, but are failing with the following screenshots?

 

We tried on all modern browser, but all are failing.

 

Thanks for your help in advance!

Lars

We finally found a solution:

there are 3 requierement for it to be working:

- custom attribute: "username" map to Username of IDP

- custom attribute "usergroup_name" map to Group of IDP (Attention: only 1 group per user is supported)

- Relay_State has to be set to base64(ResourceID_OmadaID). The ResourceID / OmadaID, can be found when clicking on the first symbol.

- create a SAML group in Omada and give the group the necessary right

 

With that being done, it works for all my instances

I am not sure if it helps, but I have similar problem with login to Omada Controlles and I have to clear cache.

Hi  @LarsK1 

 

What's the firmware version of your controller?

What type of controller are you using?

Please also try using incognito or private mode of the browsers.

  @Vincent-TP 

thanks for your quick reply. It's a linux software controller running 5.15.8.1 (Beta).

Incognito didn't change anything.

Sure  @LarsK1 

 

This is the case ID TKID250144091.

 

But the reported issue should be fixed easily by changing web browsers or PCs.

If none of them helps, please reply the support ticket email with the troubleshooting steps you have tried.

 

In the meantime, you may update the controller to the latest beta version 5.15.8.2 and see if the issue persists.

Omada SDN Controller_V5.15.8 Pre-Release Firmware(Update on Jan 8th, 2025)

 

We are planning to release a new pre-release version 5.15.20.x for linux system soon.

There is an error while perfoming saml auth:

 

 

01-22-2025 14:38:36.599 ERROR [https-jsse-nio-443-exec-5] [] o.a.c.c.C.[.[.[.[dispatcherServlet](): Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalArgumentException: Illegal base64 character 3a] with root cause java.lang.IllegalArgumentException: Illegal base64 character 3a

 

Linux controller v:5.15.8.2 (Stable)

 

I didn't get it working. For now it's dead feature, atleast for me. Maybe when controller is mature enough.

 

 

 

Best Regards,

Hi. Same for me on Linux 5.15.8.2.

 

Both Omada and Authentik are behind nginx reverse proxy, both have Letencrypt wildcard certificate. 
 

Does not matter which browser to use (Edge/Chrome) on pc or on Android. No difference if incognito mode or not. No difference if accessing directly or through reverse proxy.

 

Sorry, the browser is not compatible.

The current browser does not support Omada Controller. Please upgrade to a newer version or use other browsers.

 

Maybe my Authentik SAML application/provider config is wrong and thats why it shows this error? Looked into Omada Controller 5.14 User Guide (latest that I found online), no mention of SAML at all.
