If you have a password:

 if (Membership.ValidateUser(userName, "password")) 
 {
     FormsAuthentication.SetAuthCookie(userName, true);
     Response.Redirect("~/welcome.aspx");
 }

or if you just want to check if the user exist and log them in

 if (Membership.GetUser(userName) != null) 
 { 
     FormsAuthentication.SetAuthCookie(userName, true); 
     Response.Redirect("~/welcome.aspx");
 }

Check the Membership.GetUser method. If the user exists, you can then use FormsAuthentication.SetAuthCookie to authenticate the user.
