I've implemented a site using Umbraco 7.1.3 and configured the CMS to use Active Directory for the login. I've followed this official post (https://our.umbraco.org/wiki/how-tos/membership-providers/active-directory-membership-provider) and everything works perfectly.
My problem is when I try to create a new user using a user which has successfully logged in using It's AD credentials. Obviously the user I'm using is an Administrator of the CMS.
When I try to create this second user I get an error which points that
login name already exists
I can't find or understand what is doing Umbraco when it's configured to use AD as DefaultBackofficeProvider
.
Does it try to create an user in Active Directory?
