Delete user from Role via API or smartobject

I "think" this is covered in a sample in the documentation located here

Developer Reference > Users > Roles > How to Remove a User from a Role using the K2 API

Code from article pasted below.

//instantiates userRoleManager

UserRoleManager urmServer = new UserRoleManager();

urmServer.CreateConnection();

//build connection string

SCConnectionStringBuilder builder = new SCConnectionStringBuilder()

{

Host = "localhost",

Port = 5555,

Integrated = true,

IsPrimaryLogin = true,

};

//open connection

urmServer.Connection.Open(builder.ConnectionString);

//Get the Role you wish to modify

Role _role = urmServer.GetRole("MyRole01");

//HERE WE DO THE INCLUDE COLLECTION

//if item to remove is user and part of include list

_role.Include.Remove(new UserItem("K2:DOMAININCLUDEUSERTOREMOVE"));

//if item to remove is group and part of include list

_role.Include.Remove(new GroupItem("K2:DOMAININCLUDEGROUPTOREMOVE"));

//if item to remove is smartobject and part of include list

SmartObjectItem soItem = new SmartObjectItem();

soItem.Name = "INCLUDE SMO TO REMOVE";

_role.Include.Remove(soItem);

//HERE WE DO THE EXCLUDE COLLECTION

//if item to remove is user and part of exclude list

_role.Exclude.Remove(new UserItem("K2:DOMAINEXCLUDEUSERTOREMOVE"));

//if item to remove is group and part of exclude list

_role.Exclude.Remove(new GroupItem("K2:DOMAINEXCLUDEGROUPTOREMOVE"));

//if item to remove is smartobject and part of exclude list

SmartObjectItem soItemExclude = new SmartObjectItem();

soItemExclude.Name = "EXCLUDE SMO TO REMOVE";

_role.Exclude.Remove(soItemExclude);

//update the Role

urmServer.UpdateRole(_role);

//cleanup memory

urmServer.Connection.Close();

urmServer.Connection.Dispose();

urmServer.DeleteConnection();

urmServer.Connection = null;

urmServer = null;

// Removing the role itself.

SourceCode.Security.UserRoleManager.Management.UserRoleManager srv = new SourceCode.Security.UserRoleManager.Management.UserRoleManager();

srv.CreateConnection();

srv.Connection.Open(CreateConn());

srv.DeleteRole(new Guid("8b937e13-5947-45f6-a4fb-7603570f9660"), "Tester");

// TODO: Close connection

The user that is trying to delete the role, do they have sufficient rights to do this?

Regards,

the user is listed as an admin for the process that has these roles. I assume that means it has delete rights.

The code sample does seem to be ineffective. I was able to delete users however using the following code:

var role = urm.GetRole("My Role");

URM.UserItem user = null;

foreach (URM.UserItem item in role.Include)

{

    if (string.Compare(item.Name, "K2:DenallixMike", true) == 0)

    {

        user = item;

        break;

    }

}

if (user != null)

{

    role.Include.Remove(user);

    urm.UpdateRole(role);

}
