We have recently upgraded to version 4.62 and switched server to one that lies within our domain. Unfortunately this enables that our users may log on to Episerver with their domain accounts. These accounts do not have any permissions in our site, and are therefore thrown out. For some reason Episerver is authenticating users both from the domain and the Episerver default login system. This problem occurs only when the user has the same login name and password in Episerver as they have in our domain. Then the authentication is successful and the user logs on. Since the account doesn't have any access rights to any of the pages, the user is thrown out... What we want to do is prevent Episerver from authenticate domain accounts, and ONLY verify users in the local tblSid-table
