Fixed In Version: selinux-policy-2.4.6-349.el5 Doc Type: Bug Fix
Doc Text:
Previously, the smbd daemon service was unable to connect to the nmbd service using a Unix stream socket, which caused AVC messages to be logged in the /var/log/audit/audit.log file. To fix this bug, a set of new rules has been added to the SELinux policy to allow smbd to connect to nmbd.

AVC logs.

Description of problem:
Hi. While running this test:
https://beaker.engineering.redhat.com/recipes/1280182#task20066479
git repo:
http://pkgs.devel.redhat.com/cgit/tests/samba/tree/sanity/domain-trusts

some strange avc (which are included) raises.

Maybe this is samba bug (saddr params looks very suspicious).
