Hi, recently I come across an issue related to “Microsoft Dynamics CRM Security Provider” and “Sitecore CRM Provider”
Both have the Function, which is a way of integrating CRM and Sitecore or a C# Project.
The Sitecore CRM Provider gives you the possibility of managing the CRM Users using Sitecore Interface, therefore it’s a good integration and relatively easy to configure.
By the other Hand, Microsoft Provides some DLL that allow you to connect and consume CRM WebService including CRM Dynamics.
My Issue happened on a Project Migration, which I had to convert a Project that worked fine on Dynamics, to Office 365 Dynamics. The discussion of the Issue can be seen here
