Description Alick Zhao 2018-12-14 03:29:26 UTC
Description of problem:
Alert popped up when installing the sendmail package.
SELinux is preventing sss_cache from 'write' accesses on the directory /var/lib/sss/db.

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

If you believe that sss_cache should be allowed write access on the db 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 'sss_cache' --raw | audit2allow -M my-ssscache
# semodule -X 300 -i my-ssscache.pp
