SELinux is preventing /usr/sbin/nscd from map access on the file /usr/sbin/nscd.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that nscd should be allowed map access on the nscd 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 'nscd' --raw | audit2allow -M my-nscd
# semodule -i my-nscd.pp
