I\'m building an ASP.NET MVC 5 web site using Asp.net Identity (OWIN) and want to support both traditional username/password authentication as well as authentication against
I realize that this is an old question. I am potentially looking to do something similar but probably more like ASP.Net identity auth to more than one Azure AD tenant. I found this Integrating Azure AD into ASP.NET Core where this statement:
...then leverage the OnTokenValidated notification to implement your own issuer validation logic depending on which tenants you want to support (any tenant, Microsoft Account + specific list of Azure AD, single Azure AD, just Microsoft Account, etc)...
leads me to believe that the sample code there may hold the key to this mixed auth scenario.
