Title:
  Cannot perform certificate auto-enroll without NDES installed

Status in adsys package in Ubuntu:
  Fix Released

Bug description:
  NDES role should not be mandatory in order to perform certificate
  auto-enrollment with adsys.

  Samba/ADSys is able to take advantage of the NDES endpoint to install
  the root certificate chain, but is also able to infer the certificate
  information from LDAP.

  Due to a bug in the Samba implementation of cert-autoenroll, the root
  cert is not parsed properly if the NDES component is not installed --
  so in the current state attempting auto-enrollment without NDES
  installed will result in an error like the following:

  2024-01-08 16:11:07.809|[W26775]| Failed to fetch the root certificate chain. 
| {}
  2024-01-08 16:11:07.809|[W05621]| The Network Device Enrollment Service is 
either not installed or not configured. | {}
  2024-01-08 16:11:07.809|[W11946]| Installing the server certificate only. | {}
