Support AD or LDAPS identity stores

[AngusHooper1]

ArcGIS Monitor 2023.1 currently uses a built-in identity story which is not encouraged by security. It would help if ArcGIS Monitor was able to integrate with AD and/or LDAPS for identity management and RBAC. For example, an AD group could be linked to a collection.

Voting for this, it's definitely an important feature.

At a minimum support AD/LDAP as a IDP. Would prefer to support federation with a ArcGIS enterprise portal.

Supporting LDAP integration via one or more IdP technologies such as Okta would be preferred.
