Multi-tenancy support

[ahmedhosameldein]

Is your feature request related to a problem? Please describe.
We have a client that have users provisioned across 74 Azure AD tenants, and wants to utilize Microsoft Learn LTI

Describe the solution you'd like
We need to have a single deployment of Microsoft Learn LTI that can be used by all users in the 74 tenants (Support multi-tenancy)
As per the final comment in issue #134 "Note – These steps are not a workaround for proper Multi-Tenant behavior" , could you please document the steps for proper multi-tenant behavior

Describe alternatives you've considered
We tried the steps mentioned in issue # 134 , but still facing an issue (we are currently troubleshooting by adding extra logs):
#134

Additional context
Current issue we are facing:

• We are using LTI 1.3
• Initiate login succeed , and redirects to the LMS for login, and the LMS replies back with the token
• The call for LTI advantage launch fails with null reference exception

If you have developer resources we would welcome contributions from the community

As per #134 this is enhancement to the current solution.

Hi,

Would you be interested in testing out a change to the LTI that would support multi-tenant sign-on using Azure Business to Consumer?

I'm part of a UCL team that has been working with Lee at Microsoft to support multi-tenancy. We are finalizing a forked repo and expect to have it ready for testing within 1.5 - 2 weeks (targeting early August). We have done all our testing using Moodle which we have confirmed supports B2C authentication already.

You will need
• A B2C tenant -- you will need create one, but we have a script to help configure the remaining settings
• An LMS for testing (preferably Moodle)
• Two or more AD tenants to whitelist as part of testing

We are scripting as much of the setup and configuration as we can. So we expect the total work on your end to be about than 3 -7 hours, obviously changing based on how much testing you do.

If you are interested, I will reach back out on Github here when our changes are ready. We will have documentation ready and a form for you to fill out feedback on. We can also correspond on this issue thread if you have any issues, questions, or concerns.

Best,

Warren and the UCL Team

Update on the work by University College London - a team have been developing a solution for multiple Azure Active Directory and B2C connectivity see this fork for testing https://github.com/UCL-MSc-Learn-LTI/Learn-LTI/ the plans are for users to validate this fork and we will be working with the team to merge in features to the main branch.
