Description of problem:
The error gets thrown when navigating to an NFS share using autofs.
SELinux is preventing nfsidmap from 'read' accesses on the directory userdb.

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

If you believe that nfsidmap should be allowed read access on the userdb 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 'nfsidmap' --raw | audit2allow -M my-nfsidmap
# semodule -X 300 -i my-nfsidmap.pp
