Description Robert Koppelhuber 2025-05-25 04:25:28 UTC
Description of problem:
SELinux is preventing nmbd from 'search' accesses on the directory net.

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

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