Andreas Pieber resolved KARAF-423.
----------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 2.1.4)

Pushed in revision 1064836

I've modified your patch in the following points:

1) we typical use commons logging instead of slf4j directly
2) + e would add the class ID ; I've changed it to e.getMessage(), e); to include the entire exception in the log and not only the message

> In method KarafJaasPasswordAuthenticator.authenticate() we catch any exceptions at the end and only return false in the event of an exception
> } catch (Exception e) {
>   return false;
> }
> without logging anything about the reason for the exception, e.g. in case of a FailedLoginException. 
> I propose to add some logging in the exception handling. Perhaps at INFO level so that it gets written to the log file by default.
