The Microsoft Remote Connectivity Analyzer tool has been updated and it now includes testing for Office 365 federated identity provider. This can be used with an Office 365 tenant configured for federation with either ADFS or another WS-* based Security Token Service. It helps debug possible issues with the federated identity provider through simple tests.
The tool is available for download here. Once downloaded and installed, click on “I can’t setup federation with Office 365, Azure, or other services that use Azure Active Directory (Beta)”:
Then enter your Office 365 credentials and begin the login test of your federation configuration:
Tests are done from the PC that you download the testing tool to. It will attempt to log in to Office 365 using the federation configuration. The testing will proceed and then show results which should help debug any possible federation issues.
