This update fixes a security vulnerability where digital certificates were being returned with elevated permissions (sudo access) to users with company access. The fix ensures that digital certificates are no longer returned with these elevated permissions, protecting sensitive authentication credentials from unauthorized access.

Problem
---------
`_get_digital_signature` currently returns a sudo certificate. This is not safe.

Objective
---------
Don't return a sudo certificate to anyone having access to this company.
