I am using winbind for external authentication and since it has history of failures I have a simple watchdog implemented to check the status and restart it if necessary. That is  what happened last night and as a law abiding selinux citizen I used 'service winbind restart', but it seems the proper domain transitions is missing and winbind was started in system_cronjob_t domain instead of winbind_t and none of other domains could connect to it.

But personally would deal with this in a different way. I would write
policy for the script that restarts winbind and then i would create a
domain transition for the domain in which the script runs to winbind_t.

Mainly because i wouldnt want to extend/modify system_cronjob_t

So: system_cronjob_t -> myscript_exec_t -> myscript_t -> winbind_exec_t
-> winbind_t
