Samba build from source on Rocky Linux 9.5 problems beginning with systemd
amba /usr/local/samba/sbin/samba sudo chmod -R 744 /usr/local/samba/sbin/samba Yet I still get the same permissions issues, it mentions 'failed at step exec spawning' is there some way I can allow the samba system user account to spawn processes or is there a step I have missed here in the systemd service file or something I have done plain wrong?

09-15-2025, 08:18 PM #1Hello all, I have successfully built from source the latest SAMBA 4 to act as a domain controller on Rocky Linux 9.5 but when systemd goes to start the service I get: Jan 20 21:10:17 dc01 systemd[1]: Failed to start Samba Active Directory Domain Controller. Jan 20 21:13:04 dc01 systemd[47659]: samba-ad-dc.service: Failed at step EXEC spawning /usr/local/samba/sbin/samba: Permission denied I thought to myself that it is clearly permissions related,so I created a user account with 'useradd -r -M samba' and then in the systemd service file I set the user to samba: [Unit] Description=Samba Active Directory Domain Controller After=network.target remote-fs.target nss-lookup.target [Service] Type=forking User=samba ExecStart=/usr/local/samba/sbin/samba -D PIDFile=/usr/local/samba/var/run/samba.pid ExecReload=/bin/kill -HUP $MAINPID [Install] WantedBy=multi-user.target I then thought to myself that the path having problems is /usr/local/samba/sbin/samba so I set samba to be the owner and gave this user full read write execute permissions with: sudo chown -R sambaamba /usr/local/samba/sbin/samba sudo chmod -R 744 /usr/local/samba/sbin/samba Yet I still get the same permissions issues, it mentions 'failed at step exec spawning' is there some way I can allow the samba system user account to spawn processes or is there a step I have missed here in the systemd service file or something I have done plain wrong?
I attempted to assign ownership to root and adjust permissions once more, but the same problem persists: [dcadmin@dc01 ~]$ sudo chmod -R 744 /usr/local/samba/sbin/samba [dcadmin@dc01 ~]$ sudo systemctl start samba-ad-dc Job for samba-ad-dc.service failed because the control process exited with error code. Refer to "systemctl status samba-ad-dc.service" and "journalctl -xeu samba-ad-dc.service" for more information. [dcadmin@dc01 ~]$ ls -la /usr/local/samba/sbin/samba -rwxr--r--. 1 root root 60688 Jan 20 20:50 /usr/local/samba/sbin/samba

samba is marked as executable by adding the appropriate permissions. You can run it without root using the specified chmod command. Regarding running it as a non-root user, you may need to adjust permissions or consider alternatives since samba uses privileged ports. On RHEL systems, SELinux settings might affect access.
