Description of problem:
SELinux is preventing sh from 'search' accesses on the directory /var/lib/sss.

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

If you believe that sh should be allowed search access on the sss directory 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:
# ausearch -c 'sh' --raw | audit2allow -M my-sh
# semodule -X 300 -i my-sh.pp
