Hi All,

If you have to extend your OnPrem Active Directory infrastructure to Azure Active Directory, Microsoft introduced a powerful tool (All-in-one) called "AADC or Azure AD Connect".After installing this Sync tool, the Configuration Wizard ask for a Synchronization option :

With or Without a Seamless SSO.

To help you taking the right decision, i created and published a design considerations guide with all informations you need to know about PHS, PTA or ADFS options. Pros & Cons of each sychronization options are also listed on this document.

This guide is available on Slideshare (for reading) and Microsoft TechNet Gallery (for download).
I'm working on several Azure Security guides, they be available soon, so keep in touch :).
