Can We use OAuth/OpenId/SAML2 protocols in default apareo CAS for single sign on

[Anjali Sharma]

Hi,

We are required to implement sso by integrating CAS 4.2.7 with our application. As our application does not support  CAS protocol. So I've to implement sso either using open ID, SAML2 or OAuth protocol.

I've the below concern.

Is it feasible to implement sso using openId and oauth protocol? If yes, then please share the reference link for both protocol.

Kindly assist.

Hi,

It is possible, this is the official CAS document on OAuth, you can take a look: https://apereo.github.io/cas/4.2.x/installation/OAuth-OpenId-Authentication.html

However, I didn't start implementing OAuth untill CAS 5.2.x, so I am not sure whether or not CAS 4.2.x have good OAuth support. You might need to try out and see if it works.

Side note:  CAS 4.2.x is end of life already https://apereo.github.io/cas/developer/Maintenance-Policy.html, you might want to consider upgrading to 5.x if it is possible.

Cheers!
