Well it was long time overdue! I have been pushing this moment for a while now because there is simply to much things to master on Azure. But finally all stars were aligned today. I had to help on a project for a client that uses an Active Directory on premise.
Here is the list of topics that you have to go through (just to name a few) to master Azure AD: Azure Active Directory, Active Directory on premise, ADFS, multi-tenant, Identity management service, SSO, multi-factor authentication, B2C, OAuth, Azure Connect, forest, upn, AD roles, claims, AD users, AD groups, ADAL, federation, SAML, DirSync, Password Writeback, Password synchronization, Device writeback.
Just a lot of fun!
