Hello,

Thank you for your message. You need to build a standard ASPX form and use Kentico CMS API to create users and assign them to chosen roles.

using Kentico.CMS.DataEngine;
...

DataClass userObj = new DataClass(“cms.user”);
userObj.SetValue(“username”, “johns”);
userObj.SetValue(“fullname”, “John Smith”);
userObj.Insert();

GeneralConnection cn = new GeneralConnection();
object[,] paramsIdent = new object[ 2, 3 ];
paramsIdent[ 0, 0 ] = "@UserID";
paramsIdent[ 0, 1 ] = userObj.GetValue("userid");
paramsIdent[ 1, 0 ] = "@RoleID";
paramsIdent[ 1, 1 ] = roleId; //set appropriate value here
cn.ExecuteQuery( "CMS.User.AddToRole", paramsIdent );

Best Regards,
