Subject [jira] Created: (SSHD-102) Add error logging to org.apache.sshd.server.jaas.JaasPasswordAuthenticator.authenticate()
Date Wed, 15 Dec 2010 11:21:04 GMT
Add error logging to org.apache.sshd.server.jaas.JaasPasswordAuthenticator.authenticate()
-----------------------------------------------------------------------------------------

                 Key: SSHD-102
                 URL: https://issues.apache.org/jira/browse/SSHD-102
             Project: MINA SSHD
          Issue Type: Improvement
    Affects Versions: 0.5.0, 0.4.0
         Environment: sshd JAAS used with LDAP based authentication.

            Reporter: Torsten Mielke


The JaasPasswordAuthenticator.authenticate() method currently silently ignores any exceptions
being raised and simply returns false in case of any authentication erorrs. 
In environments where sshd is used in other frameworks like OSGi, it becomes very difficult
to trouble shoot the reasons for the authentication failure. 
Rather than simply returning false, I propose to print a logging statement at the least.

    catch (Exception e) {
            log.error("Authentication failed with " + 
                      e.getMessage() + 
                      "cause: " + 
                      e.getCause() );
            return false;
    }
