[midPoint] LDAP ressource - timeouts and sync job not restarting

[Pavol Mederly]

Hello Rainer,

in my opinion this is a bug in midPoint. The correct behavior is to 
recognize this exception as a recoverable one, and reschedule the task.

You may consider logging a JIRA issue of "bug" type.

Note that misfire action does not apply in this case, because it is 
strictly for the situations where Quartz job trigger "misfires" i.e. its 
fire time passes without the job being started. (MidPoint task manager 
uses Quartz to run midPoint tasks.)

Best regards,
