:SELinux is preventing /usr/sbin/smbd from 'getattr' accesses on the sock_file /run/winbindd/pipe.
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that smbd should be allowed getattr access on the pipe sock_file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep smbd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2012-04-20 10:33:28 EDT

Looks like you have a mislabeled directory.

restorecon -R -v /run/winbindd

Did you run winbindd outsite of the init script?

Comment 2 Stef Walter 2012-04-20 11:02:40 EDT

Yes, I probably did.

[stef@stef-desktop pbis]$ sudo restorecon -R -v /run/winbindd
[sudo] password for stef: 
restorecon reset /run/winbindd context unconfined_u:object_r:var_run_t:s0->unconfined_u:object_r:winbind_var_run_t:s0
restorecon reset /run/winbindd/pipe context unconfined_u:object_r:var_run_t:s0->unconfined_u:object_r:winbind_var_run_t:s0

So I guess this is a bogus report. Closing.
