ADFS and self signed certificate for Office 365 RRS feed

  • Question

  • Hi

    I have infrastructure at home and for the sake of testing and learning trying to configure ADFS for office 365. Now installation is quite simple however my question is whether I would be able to use self signed certificate in IIS 10 to federate office 365 tenant

    This is non production environment and it would be used only for learning purposes. I know that in production this would be bad idea however for just learning at home i would do that if it is possible

    I don't mind if i get certificate warning since I will be only person who will be logging so that is all fine with m. Just wondering would it work

  • Hi,

    Here is an article about Set up ADFS for Office 365 for Single Sign-On

    It points out that Office 365 requires a trusted certificate on your ADFS server. Therefore, you must obtain a certificate from a third-party certification authority (CA). (Step 2 in that article)

    So, I think a personal CA certificate isn't supported.
