     * If necessary, you can create and configure the defaults yourself with the following code:
     *
     * ```java
     * TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(
     * TrustManagerFactory.getDefaultAlgorithm());
     * trustManagerFactory.init((KeyStore) null);
     * TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();

            logger.debug("role: {}", roleSet);
        }
        final String[] roles = roleSet.toArray(new String[roleSet.size()]);

        if (!subRoleSet.isEmpty()) {
            TimeoutManager.getInstance().addTimeoutTarget(() -> {
                processSubRoles(ldapUser, bindDn, subRoleSet, groupFilter, roleSet);
                if (logger.isDebugEnabled()) {
                    logger.debug("role(lazy loading): {}", roleSet);
