Fix certification fqdns and entra connect not required

[ghost]

Description

*.domain.com doesn't include domain.com. At least one deployment showed, that the root-sub domains of digicert are used.

During testing I noticed, that ipg_entra_connect_id variable was mandatory, although it shouldnt be, as it was a backward compatible feature and it borke the basic example.
