Bug 821420 - SELinux is preventing /usr/bin/bash from 'read' accesses on the file /var/lib/sss/mc/group. This file (which is actually the on-disk representation of a mmap() cache) needs to be readable by any process. It should only be writable by SSSD processes.

:SELinux is preventing /usr/bin/bash from 'read' accesses on the file /var/lib/sss/mc/group.
:*****  Plugin leaks (86.2 confidence) suggests  ******************************
:If you want to ignore bash trying to read access the group file, because you believe it should not need this access.
:Then you should report this as a bug.  
:You can generate a local policy module to dontaudit this access.
:# grep /usr/bin/bash /var/log/audit/audit.log | audit2allow -D -M mypol
:# semodule -i mypol.pp
:*****  Plugin catchall (14.7 confidence) suggests  ***************************
:If you believe that bash should be allowed read access on the group file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep prelink /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
