is this something to do with the Microsoft Graph SDK that is being used for these labs? seeing lots of activities in changes here? @garethj-msft

[garethj-msft]

Graph SDK isn't being used for OneNote cos it's not 1.0

[DianeD]

unable to repro error. Assigning to @vsharma77 to retest too.

[DianeD]

@lucas66 can you share your project?

[lucas66]

This might be related to issue #102. All Graph AAD Auth v1 starter project templates are throwing this error for me. @DianeD how would you like me to share?

[DianeD]

@lucas66 can you send a link to a share or put the project folder here? https://github.com/OfficeDev/office-docs/tree/master/O3653/O3653-7%20Deep%20Dive%20into%20the%20Office%20365%20APIs%20for%20OneNote%20services/Labs/Completed

[lucas66]

@DianeD my project is here: https://github.com/OfficeDev/office-docs/tree/master/O3653/O3653-7%20Deep%20Dive%20into%20the%20Office%20365%20APIs%20for%20OneNote%20services/Labs/Completed/OneNoteDev-lucas66

It is a raw project, you'll have to build it to restore the nuget packages then deploy it.

[DianeD]

Thanks @lucas66. Is this just the empty project created from the template? I don't see any OneNote content. I was able to log in okay with my test credentials.

[DianeD]

@lucas66 can you try this change from @jasonjoh since I can't repro?

...this may be an issue where OpenID says you are authenticated but actually has no identity. Can you try replacing this line in _Layout.cshtml:

@if (Request.IsAuthenticated)

With:

@if (Request.IsAuthenticated && null != System.Security.Claims.ClaimsPrincipal.Current && null != System.Security.Claims.ClaimsPrincipal.Current.FindFirst("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn"))

[lucas66]

@DianeD The fix from @jasonjoh worked and got me past the initial error. Should replacing the line in _Layout.cshtml be a step in the lab.md?

[DianeD]

Great! If we don't have time to update the template, then yes. @jthake @keyur32

[jthake]

I have no idea how to change the template. @jasonjoh do you have time to change it and send it to me so I can update the Master VM? be a shame to have to add this to ALL labs as an additional step.

[jasonjoh]

I just got in. I can send you a new _Layout.cshtml file that you would just need to replace inside the template zip files. I'll email that to you shortly.

[jasonjoh]

Ok, I wasn't able to drop them into the zips, so I just created new zips and put them on my OneDrive for Biz. Sent you a link Jeremy.
