I am trying to implement a form that will allow a department to manage who can view certain folders.  As part of that process I'm trying to implement a workflow that will add a Windows user to a repository group.  The workflow fails to add the user with the warning "Trustee not found. [9012]"

Imports System
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Data
Imports System.Data.SqlClient
Imports System.Text
Imports Laserfiche.RepositoryAccess

Namespace WorkflowActivity.Scripting.SDKScriptAddUserToLFGroup
    '''<summary>
    '''Provides one or more methods that can be run when the workflow scripting activity is performed.
    '''</summary>
    Public Class Script1
        Inherits RAScriptClass104
        '''<summary>
        '''This method is run when the activity is performed.
        '''</summary>
        Protected Overrides Sub Execute()
            'Write your code here. The BoundEntryInfo property will access the entry, RASession will get the Repository Access session
            Dim inUserID As String = GetTokenValue("inUserID")(0)
            Dim inGroupName As String = GetTokenValue("inGroupName")(0)
            Dim inGroupAcct As AccountInfo = Account.GetInfo(inGroupName, RASession)
            Dim inUserAcct As AccountReference = New AccountReference(inUserID, RASession)
            Dim UserGroup As GroupInfo = CType(inGroupAcct, GroupInfo)
            UserGroup.AddMember(inUserAcct)
            UserGroup.Save
        End Sub
    End Class
End Namespace

It works fine... if I don't execute the Save :)
