Description Adam Williamson 2017-08-14 23:47:45 UTC
Description of problem:
Happened in normal system use (probably only with postfix enabled, if I recall what 'qmgr' is a part of) after the 'map' permssion was introduced.
SELinux is preventing qmgr from 'map' accesses on the file /var/lib/sss/mc/initgroups.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that qmgr should be allowed map access on the initgroups 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:
# ausearch -c 'qmgr' --raw | audit2allow -M my-qmgr
# semodule -X 300 -i my-qmgr.pp
