Hi Guys,

I am going to set it up so when a member logs in to the front end, if there is a user in the backend with the same username and password i log them in to the front end so they can get a list of docs to preview with front-end livery etc..

yes it is reinventing the wheel!

but just wondering could i do something like this:?

public partial class LoginUserControl : BasePage
protected void MemberLogin_OnLoggedIn(object sender, System.EventArgs e)
        {
            var member = Member.GetCurrentMember();

            //if the member is a content admin person then attempt to log them in to the back-end
            if ((member != null) && (member.Id > 0) && Roles.GetRolesForUser(member.LoginName).Any(r => ContentEditorRoleNames.Contains(r)))
            {
                // Authenticate users by using the provider specified in umbracoSettings.config
                if (Membership.Providers[UmbracoSettings.DefaultBackofficeProvider].ValidateUser(MemberLogin.UserName, MemberLogin.Password))
                {
                    if (Membership.Providers[UmbracoSettings.DefaultBackofficeProvider] is ActiveDirectoryMembershipProvider)
                        ActiveDirectoryMapping(MemberLogin.UserName, Membership.Providers[UmbracoSettings.DefaultBackofficeProvider].GetUser(MemberLogin.UserName, false).Email);

                    umbraco.BusinessLogic.User u = new User(MemberLogin.UserName);
                    doLogin(u);
                }
                else
                {
#warning report some exception about not logging someone in to the back-end
                }
            }
        }

        /// <summary>
        /// Maps active directory account to umbraco user account
        /// </summary>
        /// <param name="loginName">Name of the login.</param>
        private void ActiveDirectoryMapping(string loginName, string email)
        {
            // Password is not copied over because it is stored in active directory for security!
            // The user is create with default access to content and as a writer user type
            if (umbraco.BusinessLogic.User.getUserId(loginName) == -1)
            {
                umbraco.BusinessLogic.User.MakeNew(loginName, loginName, string.Empty, email, umbraco.BusinessLogic.UserType.GetUserType(2));
                umbraco.BusinessLogic.User u = new umbraco.BusinessLogic.User(loginName);
                u.addApplication("content");
            }
        }

        string[] ContentEditorRoleNames = new[] { "Content Editor", "Content Approver", "Administrator" };
