Description of problem:
SELinux is preventing sssd from read, write access on the file cache_implicit_files.ldb.

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

If you believe that sssd should be allowed read write access on the cache_implicit_files.ldb file 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 'sssd' --raw | audit2allow -M my-sssd
# semodule -X 300 -i my-sssd.pp
