Description James 2023-03-21 23:26:05 UTC
Description of problem:
Attempting to automount an SMB3 share with sec=krb5.
SELinux is preventing cifs.idmap from 'write' accesses on the sock_file /var/lib/sss/pipes/nss.

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

If you believe that cifs.idmap should be allowed write access on the nss sock_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 'cifs.idmap' --raw | audit2allow -M my-cifsidmap
# semodule -X 300 -i my-cifsidmap.pp
