First off, let me state the end goal. We have Office365 for Mailboxes, and the free version of Azure AD that comes with it. We want to get access to LDAP within Azure Directory Services to enable SingleSignOn for ServiceNow. I realize that the free version of Azure doesn’t come with Directory Services, so we are willing to upgrade in order to accomplish this.
Would we need the Basic version of Azure AD DS? Or P1/2? We do not have any on-prem domain controllers to connect to, so this would be a cloud only solution.
