Presently there are a lot of options for single sign on that can be used with the application server, it could be useful to pull all of these into a single document.

• WildFly Clustering SSO
• Kerberos
• SAML
• KeyCloak
• OpenID Connect

For anyone tasked with implementing "SSO" this should give enough information to select between the available options.

From that point we should document how to implement each of these options possibly with further sub options identified.
