If you follow the latest developments in the Entra space, you have no doubt come across Merill Fernando. In this episode Merill joins us for a great discussion as we geek out about Entra and authentication in general. Why is it called Entra (RIP AAD!)? Merill sheds some light on the name change, we talk about AD FS and its relevance today, discuss the deprecation of AzureAD and MSOnline PowerShell modules and introduce some of the great tools and resources he's developed for the community. Merill Fernando is a Principal Program Manager at Microsoft and Senior member of the "Customer Success Team" engaging with Microsoft Entra customers and guiding them through deployments, planning, debugging and driving feedback into the feature teams.
