Grant a User Permission to ONLY Start/Stop (OpenVPN) service

[Lamia]

Hi,
I have searched the forum and the Internet but no clue hence, I am posting the question here. I have set up a user and a new group. The user belongs to the group. I have added all permissions to OpenVPN yet on logging in, the user cannot stop or restart the service. At the moment, the animation is played on hitting the button i.e. restart shows a rolling wheel but the service is not restarted. The same goes for the stop button.

I cannot drop the user in the admin group since they have a limited privilege. What privileges need to be added in addition to the below?

VPNAdmins	WebCfg - OpenVPN: Client Specific Override	Allow access to the 'OpenVPN: Client Specific Override' page.	
VPNAdmins	WebCfg - OpenVPN: Clients	Allow access to the 'OpenVPN: Clients' page.	
VPNAdmins	WebCfg - OpenVPN: Clients Edit Advanced	Allow edit access to the 'OpenVPN: Clients' Advanced settings field. (admin privilege)	
VPNAdmins	WebCfg - Diagnostics: Reboot System	Allow access to the 'Diagnostics: Reboot System' page.	
VPNAdmins	WebCfg - System: Group Manager: Add Privileges	Allow access to the 'System: Group Manager: Add Privileges' page. (admin privilege)	
VPNAdmins	WebCfg - System: User Manager: Add Privileges	Allow access to the 'System: User Manager: Add Privileges' page. (admin privilege)	
	WebCfg - Status: OpenVPN	Allow access to the 'Status: OpenVPN' page.	
Security notice: This user effectively has administrator-level access	

I reckon all of these are not necessary, I will remove them. Kindly guide me. Thanks.

There are no granular per-service privileges right now, so any user who must control a service requires access to status_services.php (WebCfg - Status: Services).

All of the service control links, even in the shortcut bar, use that page to manage service control.
