Does OpenAM support sso protocol CAS(apereo CAS)?

[zzfire]

Hi Team,

CAS(apereo CAS) is not that popular compared with OIDC, SAML2，but still popular used in our company. I read the docs and searched here and other places by google, but found no userful information. So I have some questions about CAS:

• Does OpenAM support that?
• If not officially supported, any plugins about that?
• Or how to add the CAS support into OpenAM, which documents or projects, or video should I read and follow?

and another question is about, why not support CAS, is it ugly or not safe enough? :)

Thanks
