Azure AD Directories and B2B user decision matrix – One-slider

Click for larger version

Ever pondered on how to decide about B2B Account Types? One thing is for sure, If you’re enterprise org, you’re better of having multiple partner account types, because it’s not one size fits all type scenario

  • The matrix makes clear separation between collaboration only, and administrative tasks performing partners
    • This is based on multiple recommendations, but is based mostly on the following Azure Subscription recommendation from Azure Secure DevOps Kit. (Obviously if the account is also homed in Azure AD and you’ve setup B2B conditional access policy for guests, you might consider yourself covered to some extent…)

  • Where authentication happens is important part on the picture, and is the main deciding factor on users home directory

Other considerations

  • Licensing is separate discussion… Anyway key takeaway is, that the 1:5 ratio licensing works in the background = If you assign license to guest user its one license gone, and doesn’t benefit from the B2B-Licensing
  • The picture doesn’t consider SSO between the host tenant and its IDP, as it basically wouldn’t add anything to the picture (unless you’d ”multiplex” multiple claims provider against single AD FS, and then via claims pipeline transformations emit claims for the guest type users in you’re tenant)
  • More detailed explanation of all the scenarios (minus the flowchart) can be found here Properties of an Azure Active Directory B2B collaboration user

Please don’t hesitate to comment or send feedback, if you notice any errors or wrong assumptions in the flowchart
