JAZN-LDAP : retrieve inetOrgPerson attributes from principal object

Question

Hello.
I 've extended callerInfo demo (in OC4J distrib :j2ee/home/jazn/demo) :
1. use of JAZN-LDAP
2. now the servlet prints the "HttpServletRequest.getUserPrincipal()" object attributes (class implementation : oracle.security.jazn.oc4j.JAZNUserAdaptor) : the servlet prints LDAP attributes like user DN, subscriber name, groups member, ....
Is it possible to retrieve other attributes of the LDAP object user (like description, businessCategory) by the java.security.Principal interface ?
Thanks.

Try this
public String getCompanyByUserDN(String userDN) throws Exception
String result = null;
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://<<LDAP HOST>>:<<LDAP PORT>>");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, <<User DN>>);
env.put(Context.SECURITY_CREDENTIALS, <<User Password>>);
DirContext dirCtx = new InitialDirContext(env);
DirContext userCtx = (DirContext)dirCtx.lookup(userDN);
Attributes attrs = userCtx.getAttributes("", new String[] {"o"});
result = (String)attrs.get("o").get();
return result;
}
