I think I now understand your issue. I was faced with a similar problem and could not figure out how to get the roles of an authenticated user through the servlet API.
It seems to only allow the question 'request.isUserInRole(role)'. But does not seem to provide a way to get a list of roles that the user is in. I used a kludge whereby I defined the valid roles in a context init parameter (bad duplication of effort). Then used 'request.isUserInRole(role)'. I did not think to cast the 'request.getUserPrincipal()' return value. Please post if your methodology works.

Does this mean you are doing > authentication from within your web app? My application is exposing a SOAP service (through Spring-WS servlet) for which I want to do method-level access control. Since the service endpoint already uses container-based HTTP Basic authentication, I'd like to reuse the realm implementation (and configuration, obviously) in my own code to get hold of the user's roles. I just found HttpServletRequest#getUserPrincipal() , maybe I can just downcast the result to org.apache.catalina.realm.GenericPrincipal and invoke getRoles() on this... ugly, but well... ;) Cheers, Tobi > > Oliver > > > > -----Original Message----- > From: [email protected] on behalf > of Tobias Gierke > Sent: Tue 6/11/2013 11:20 AM > To: [email protected] > Subject: Possible to expose a Tomcat Realm instance through JNDI ? > > Hi, > > In my web app, I'd like to re-use the (server-wide) Tomcat Realm that is > already being used for HTTP Basic authentication but couldn't find a way > how to get hold of the actual Realm instance. > > I spent quite some time looking for a solution (complicated by the fact > that most Google hits actually referred to the LDAP authentication > realm) but found none.
