Example: Manual Precedence Using the Last Contributing Management Agent

The following example shows you how to set the value for an attribute that is configured for manual precedence only if a specified management agent changes the value. The first time the attribute is set, the example sets the attribute. From then on, only the management agent that first set the attribute is allowed to change the attribute. Other management agents cannot change the attribute value.

    Public Sub MapAttributesForImport(ByVal FlowRuleName As String, _
        ByVal csentry As CSEntry, _
        ByVal mventry As MVEntry) _
        Implements IMASynchronization.MapAttributesForImport
    
        Select Case FlowRuleName
            Case "Given Name Precedence"
                Const MVAttributeName = "cn"
                Const CSAttributeName = "displayName"
                If mventry(MVAttributeName).IsPresent Then
                    ' Only allow the original management agent to modify the attribute.
                    If mventry(MVAttributeName).LastContributingMA.Equals(csentry.MA) Then
                        mventry(MVAttributeName).Value = csentry(CSAttributeName).Value
                    Else
                        Throw New DeclineMappingException
                    End If
    
                Else
                    ' This is the first time the attribute is being set.
                    mventry(MVAttributeName).Value = csentry(CSAttributeName).Value
                End If
        End Select
    End Sub

    void IMASynchronization.MapAttributesForImport(string FlowRuleName, 
        CSEntry csentry, 
        MVEntry mventry)
    {
        switch(FlowRuleName)
        {
            case "Given Name Precedence":
                string MVAttributeName = "cn";
                string CSAttributeName = "displayName";
                
                if(mventry[MVAttributeName].IsPresent)
                {
                    // Only allow the original management agent to modify the attribute.
                    if(mventry[MVAttributeName].LastContributingMA.Equals(csentry.MA))
                    {
                        mventry[MVAttributeName].Value = csentry[CSAttributeName].Value;
                    }
                    else
                    {
                        throw new DeclineMappingException();
                    }
                }
                else
                {
                    // This is the first time the attribute is being set.
                    mventry[MVAttributeName].Value = csentry[CSAttributeName].Value;
                }
                break;
        }
