Description of problem: logged in to kde-4.11.0 session is all SELinux is preventing /usr/libexec/accounts-daemon from using the 'net_bind_service' capabilities. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that accounts-daemon should have the net_bind_service capability by default. Then you should report this as a bug. You can generate a local policy module to allow this access.

Any idea why accountsd would be binding to a port < 1024
honestly no, accountsservice is still largely a black box (with a neato dbus interface) to me. I'll try to ask around and find out though.
For what it's worth, it must be temporary (on startup?)... just checked with lsof, and it's currently not listening.

Are you running with NIS?
Yes, I am running with NIS.
(In reply to Daniel Walsh from comment #6) > Are you running with NIS? Yes, I'm also running NIS.
It looks like nis or glibc must have changed to allow priv apps to bind to ports < 1024 fairly recently. I added a dontaudit for this in git. a13733d1b028ec3ca4db41d3468b486113c7da5b, nis should continue to attempt to bind to random ports until it gets one > 1024.

Reassigning to ypbind package to see if they know anything.
Rex do you know about anything that might have changed to cause this?
(In reply to Daniel Walsh from comment #11) > Reassigning to ypbind package to see if they know anything. Well, we did nothing serious in NIS packages (ypserv, ypbind, yp-tools) that could influence SELinux access for couple of months. I also don't understand how did you come to ypbind to cause this problem, since I don't probably understand enough what's happening in accounts-daemon that could be related to NIS. Could anybody explain to me the connection of accounts-daemon and ypbind, please? What I noticed only are some NIS-related changes in selinux-policy, so maybe that could help: * Fri Sep 06 2013 Lukas Vrabec <lvrabec@redhat.com> 3.12.1-74.2 - Dontaudit attempts to bind to ports < 1024 when nis is turned on * Thu Aug 08 2013 Miroslav Grepl <mgrepl@redhat.com> 3.12.1-70 - Make NFS home, NIS authentication and dbus-daemon working * Tue Mar 26 2013 Miroslav Grepl <mgrepl@redhat.com> 3.12.1-24 - Allow yppasswdd to use NIS * Wed Jan 23 2013 Miroslav Grepl <mgrepl@redhat.com> 3.12.1-6 - Dontaudit thumb drives trying to bind to udp sockets if nis_enabled is turned on * Wed Jan 16 2013 Miroslav Grepl <mgrepl@redhat.com> 3.12.1-5 - Dontaudit thumb drives trying to bind to udp sockets if nis_enabled is turned on
Ok I think we will just don't audit for now and see if there are other problems. Fixed in 3.12.1-74.2
OK. Changing the component as well so it corresponds with the actual fix made.
