Does Azure AD support LDAP? At least in the beginning it didn’t, but I haven’t come across a definitive answer. There is a new RESTful API called Azure AD Graph. (If I have understood correctly, the MS LDAP implementation didn’t scale well to Azure proportions.) (I’m sorry I am late to the party.) -- Cheers Petri GSM +358 400 505 939
