SVN authentication using ldap with glassfish server

For my bachelor thesis I have to extend an existing web application (written in JavaEE, GlassFish as application server) with some functionality, e.g. providing svn within that app.

The user authentication is done via the LDAP service of the university, say: only members of the university can use the application. User credentials for every svn repository are exactly the same as the login credentials (every member of the university has an unique id + password, used for all services [mail, svn, printing, ...] provided by the university).

Is it possible that any logged in user can operate (very basic functionality) with given repositories through the web application? If so: What are the steps to take? If no: What are the alternative solutions?

Any help is much appreciated. :)
