    Custom Login using SSL

    Carolyn Cole Newbie


      Is there any way to get access to the X509 certificates passed in SSL in a Custom Login Module?

      I am trying to verify a user using the certificate DN as the username that I can then use to look up information about the user in an LDAP server.

      Thanks for any help you can give me!

          Here is a method you could use inside a login module. It assumes you extend the AbstractServerLoginModule.

          private Object[] getLoginInfo() throws LoginException {
           if (callbackHandler == null) {
           log.warn("No callbackHandler available");
           throw new LoginException(
           "Error: no CallbackHandler available " + "to collect authentication information");
           String username = null;
           X509Certificate[] certs = null;
           NameCallback nc = new NameCallback("username");
           ObjectCallback oc = new ObjectCallback("certs");
           Callback[] callbacks = { nc, oc };
           try {
           username = nc.getName();
           Object credential = oc.getCredential();
           if (credential == null || !(credential instanceof X509Certificate[])) {
           log.debug("No X509Certficate chain");
           throw new LoginException("No X509Certficate chain");
           certs = (X509Certificate[]) credential;
           } catch (java.io.IOException ioe) {
           throw new LoginException(ioe.toString());
           } catch (UnsupportedCallbackException uce) {
           throw new LoginException("CallbackHandler does not support: " + uce.getCallback());
           return new Object[] { username, certs };
