JAAS - NTSID to "friendly" name

[Jared Krull]

I'm using JAAS to authenticate my app against an NT domain and would like to use my app to look through the different security groups associated with the user.

I create my LoginContext, then login, then looking through the returned Principal objects:

    
lc = new LoginContext("Main", new NullCallback());
lc.login();
for(Principal p : lc.getSubject().getPrincipals()){
    System.out.println(p.getName());                
}

All's well so far but when the Principal is a group, the only data I can get is the SID reference (looks like "S-1-5-22-534") and not the name that is used to setup the group.

I'd like to find a way to resolve the SID to the actual name of the group.

Is that possible?
