Use the code from the Login module as an example. I have done this for an application, and it works just fine. If you need more, I can dig up the sample code that I used.

Excelent!
Good idea.
Can you dig up your code please?

Thank you bery much for your assistance !

Thanks!

 

Here is a chunk of code, with no guarantees that it works.  I just grabbed it, copied it, and pasted it here.  I hope it helps.

            try
            {
                //validate username/password combination
                DotNetNuke.Entities.Users.UserInfo myUser = new DotNetNuke.Entities.Users.UserInfo();
                DotNetNuke.Security.Membership.UserLoginStatus userLoginStatus = new DotNetNuke.Security.Membership.UserLoginStatus();
                myUser = DotNetNuke.Entities.Users.UserController.ValidateUser(myPortal, myUsername, myPassword, "", "", "", ref userLoginStatus);

                Label1.Text += "userLoginStatus: " + userLoginStatus.ToString() + "
";

                if (userLoginStatus == DotNetNuke.Security.Membership.UserLoginStatus.LOGIN_SUCCESS ||
                   userLoginStatus == DotNetNuke.Security.Membership.UserLoginStatus.LOGIN_SUPERUSER)
                {
                    //login the user ...
                    DotNetNuke.Entities.Users.UserController.UserLogin(PortalId, myUser, "", "", true);
                    loggedIn = true;
                    loginFailed = false;
                }
                else
                {
                    loggedIn = false;
                    loginFailed = true;
                }
            }
            catch
            {
                loggedIn = false;
                loginFailed = false;
            }
