[FEATURE]: Expanded LDAP configuration options

[johwhite-nvidia]

Describe the solution you'd like
The LDAP module provides a very basic subset of the full configuration options. Key features like a distinct group_base_dn, setting authorization off and setting a provider-domain are absent.

Describe alternatives you've considered
The only clear alternative automation to my mind is to spawn off a distinct shell command which would require setting up ssh keys, etc. Beyond that, it's a manual step in our setups.
