Description of problem:

Please refactor following unnecessary while loop:

"
                    while (answer.hasMoreElements()) {
                        // Print the objectGUID for the user as well as URI and query path
                        String guid = guidFromResults(answer.next());
                        if (guid == null) {
                            break;
                        }
                        userGuid.append(guid);
                        logQueryContext(userGuid.toString(), uri.toString(), currentLdapServer);
                        return AuthenticationResult.OK;
                    }

"

In any case this loop runs only once so the problem solved by it can be
replaced by "if" decission statement.
