Description Enrique Meléndez 2025-08-27 19:40:05 UTC
Description of problem:
sshd with 2fa via pam_oath.so
SELinux is preventing sshd-session from 'read' accesses on the lnk_file /var/lock.

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

If you believe that sshd-session should be allowed read access on the lock lnk_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 'sshd-session' --raw | audit2allow -M my-sshdsession
# semodule -X 300 -i my-sshdsession.pp
