Open Source Document Management System | OpenKM

We have a requirement to implement a Single Sign On (SSO) solution to a number of applications of which OpenKM is one. We currently have the Community edition installed and are busy implementing Gluu (https://www.gluu.org/) as our SSO solution. I'm a little bit of a newbie to both Gluu and OpenKM but my understanding is that Gluu can use one of several industry standard methods to communicate with the applications such as SAML, OAuth 2.0 or OpenID Connect. My question is, has anyone out there done anything similar or have any advice on how it may be achieved?

From OpenKM side, if you want to change authentication you should concentrate in Spring Security ( OpenKM.xml and some related classes ).

I think you could start looking information about "spring oauth2 example" or "spring saml" at google.
