Review Comment:
   LDAPLoginModule could throw NoCacheLoginException caused by LoginException?
   ```suggestion
         Throwable rootCause = ExceptionUtils.getRootCause(e);
         if (noCacheExceptions.contains(rootCause.getClass().getName())) {
            NoCacheLoginException noCacheLoginException = new 
NoCacheLoginException(rootCause.getClass().getName() + (rootCause.getMessage() 
== null ? "" : ": " + rootCause.getMessage())));
            noCacheLoginException.initCause(e);
            return noCacheLoginException;
         }

Review Comment:
   If LDAPLoginModule throws NoCacheLoginException, the instanceof check is not 
required
   ```
            } catch (NoCacheLoginException e) {
               logger.debug("Handling NoCacheLoginException", e);
               throw e;
