I cannot begin to tell you how wonderful WSO2 ESB is for our SharePoint Server 2013 platform. You’ve made integrating ADFS 2.0 with NTLM authentication a breeze! The tutorials were delicately detailed, wonderfully written, and, best of all, easy. I had hardly any trouble getting WSO2 ESB configured as a Windows Service to use with our SharePoint web applications.
Thank you for putting such care into the product you have created! I look forward to using other products WSO2 produces.
