We just upgraded CRM from 2011 to 2015.

I added a http binding just like we had in 2011. Navigating directly to the CRM 2015 via http apparently will not authenticate and the dialog box just keeps poping up for user and pass. SSL works fine of course. AS I researched it looks like WCF now handles the authentication and will not pass http or allow for more than one bind?

We are using a Nintex plugin for SharePoint 2010 that only allows for HTTP connections to Dynamics and not HTTPS.

Any ideas or work around on this?
