Hi, Kazim. In Gluu Server there is a feature called "person authentication scripts". That's a script written in Jython that implements a custom authentication method, allowing you to extend basic authentication options Gluu offers. We also have a ready to use CAS person authentication script, so you can delegate user authentication to your existing CAS server. Hope this helps.

Hi Aliaksandr, I look for "CAS person authentication script" in "Manage Custom scripts" section. I could not find it. Are there any documentation about usage of "CAS person authentication script" in Gluu Server. Regards.

Hello, I accidentally closed ticket and could not find the way to open it. Are there any documentation about usage of "CAS person authentication script" in Gluu Server? Regards.

Hi, Kazim. I've re-opened the ticket for you. The script is located [here](https://github.com/GluuFederation/oxAuth/blob/master/Server/integrations/cas2/Cas2ExternalAuthenticator.py). You'll need to add it manually to your instance at "Manage custom scripts" page. I don't think we have a doc (I'll need to check) - it's rather rarely used one (just one or two our customers use it atm, I believe). I'll get back to you soon with more information on how to use it.

Yes, it just to be added in Person Authentication Script ( under "Manage custom script" section ). After that, this is how it will work. SP/app/RP --> Gluu Server ( no Gluu server authentication ) --> CAS login --> After successful CAS login --> Gluu Server --> SP/app/RP. User will only get CAS login page in this whole scenario.
