Authentication server for Google Apps

Question

We are using Google Apps services in our startup for email and docs. However for some other purposes such as svn and bug tracker we have our local machines on which we have installed the required apps. All of them have their own separate credentail sets.

Ideally I'd like to have one authnetication (i.e. that of Google Apps) and authenticate on svn & trac etc. using them. Considering Google Apps does not support OpenID, what should be a good solution? Can I setup a server which uses a particulr protocol and still nicely wraps around Google Apps authentication?

Answer 1

OAuth may help, up to a point -- Google Apps' gdata APIs do support it decently, see here. Of course all this requires and concerns programming, not just system administration: but then I know for sure your question IS about programming, since it's on Stack Overflow -- if you meant to ask strictly about sysadm issues, you would of course be using serverfault.com, right?-)

Answer 2

There is a Google Federated Login API now, it provides OpenID services. Also, as this guy has shown, it's easy to use Google App Engine to create an OpenID provider of your own using Google IDs as the underlying credentials. HTH.
