Tip #1122: Multiple tokens in cache

Golf balls in a bucket

If you are working with multiple user or app identities (e.g. for testing), and the code uses ADAL, and especially if the application is killed or crashes, you may occasionally get an error: multiple_matching_tokens_detected: The cache contains multiple tokens satisfying the requirements.

Tip #1112: Impersonate Azure AD users

Elvis impersonator

Developers are familiar with the concept of impersonating Dynamics 365 users. It’s easy – all you need to do is to add MSCRMCallerID header to your Web API request, and you’re done (assuming that you have prvActOnBehalfOfAnotherUser privilege).

The side-effect of this awesomeness is that URLs and unique names may no longer match, leading to the fun times with connections. Here’s the […]

Occam's razor

As developers, from time to time we are puzzled by simple questions: How to discover Azure AD tenant ID based on Dynamics 365 organization URL?

Tip #1032: Be careful with those function names

Namespaces

Today’s tip is from Tom Pickles – thank you! And, hey, you can be a guest tipster too – just send your tip to jar@crmtipoftheday.com. I fixed a curious issue today that I thought I’d share. Users had reported that when using the multi-edit form to update multiple cases, the form would freeze when they […]

Tip #1013: Include attributes that are not there

Hidden figure

New Developer Guide, as it turned out, contains a lot of useful nuggets, little enhancements that make developer’s life much easier. How many times did you need some field values for the use in javascript but didn’t really want to include the fields on the form? Something like lattitude and longitude, for example. Would it […]
