Greetings all, I need a bit of advice/help with this.

Been struggling with Office365 for business for two weeks now. I have a working example running in blank Web Forms project which I am trying to ported into DNN module (based on Chris Hammond template).

The very first problem was:

Exception: No owin.Environment item was found in the context.

From my understanding had something to do with DNN not being able find/run Startup.cs. So, I thought that I wasn't allowed to have Startup.cs in the module and I was proven wrong. DNNChat module also uses Startup.cs to reference SignalR.

After I flipped owin:AutomaticAppStartup value from false to true in DNNs web.config I started to have issues with Microsoft.Owin.Security 2.1.0.0 library not being found.

Adding some assembly bindings to DNNs web.config to reflect update dll's solved that issue and I am now able to run the module inside DNN.

But when I click on Sign In button I get redirected to my website home page not to the https://login.windows.net as I would expect. So I though maybe its FriendlyURL engine, nope, disabling Friendly URLs didn't help.

And now I am sitting here thinking that DNN must be hijacking HttpContext in some way.

Any one have any suggestion where I should look next?

Hrm, been trying something with request filters with not much luck.

It looks like when I click Sign In button DNN takes over and attempts to redirect me to the Login page but because I am already authenticated with DNN it redirects me to the home page.

Is there a way I can prevent default behaviour with request filters or web.config tweaks?

It appears you're using OWIN's authentication middleware (which uses localdb and entity framework by default -

http://www.asp.net/identity/overview/getting-started/adding-aspnet-identity-to-an-empty-or-existing-web-forms-project ). This is why it's failing as DNN is a webforms environment set up for forms authentication. AFAIK there is no requirement for OWIN auth middleware to use Office API's, it's more likely that you need to use OAUTH (which is an option with OWIN), if this is the case, just use DNN's oauth support (you can look at authentication providers such as google/live/twitter to see it in action)

I was looking at OpenID Authentication last night till it fried my brain.

Will give the others a try shortly.

Cheers Cathal.
