I have a public Internet facing site running on SHarePoint 2010 using NTLM authentication. Users using FireFox/Chrome/Safari are able to log into the site using just their username and password. Internet Explorer users, however, are forced to log in with domain\username. If the domain is left out the site will not grant the user access.
I have been instructing users to try to use another browser but most of our user base uses IE. We have two separate domains. Internal users belong to DomainA and External users are in DomainB. I am not sure why IE is forcing the inclusion of the domain in the username while the others do not. I need users to be able to log in with just username and password only. Has anyone seen this before? Thanks!
