Authorize non admins to change the due date

Authorize non admins to change the due date

hello,

we're having problems with authorizing non-admin users to change the due date.
The technician roll has full control on the request form, but still can't change the due date.

I know the due date will automatically change when changing the priority or the SLA, but we want to edit it manually.

Any help is welcome.

Kind regards,

Luc Janssen
