If you try to link multiple connector space objects to the same Forefront Identity Manager Synchronization Service (FIM Synchronization Service) database (metaverse) object, FIM Synchronization Service issues an ambiguous-import-flow-from-multiple-connectors error. To prevent this error, you must explicitly assign values from the connector space object attributes to the metaverse object attributes.

The following example shows how to handle the value of the samAccountName and mailNickName attributes from multiple connector space objects of the same management agent to the same MVEntry object. If the attributes exist in the connector space object and have at least one value, those values are assigned to the samAccountName and mailNickName attributes of the metaverse object.

Before you use this rule extension, you must modify the metaverse attribute flow precedence rules in the Metaverse Design window so that it allows manual precedence rules to be applied to this attribute.

Visual Basic  Copy Code
Public Sub MapAttributesForImport(ByVal FlowRuleName As String, _
	ByVal csentry As CSEntry, ByVal mventry As MVEntry) _
	Implements IMASynchronization.MapAttributesForImport

	Select Case FlowRuleName
		Case "IAF_samAccountName"
			Replace(csentry, mventry, "samAccountName", "samAccountName")
		Case "IAF_mailNickName"
			Replace(csentry, mventry, "mailNickName", "mailNickName")
		Case Else

		' TODO: Remove the following statement and add your code here.
		Throw New EntryPointNotImplementedException()

	End Select
End Sub

Public Sub Replace(ByVal csentry As CSEntry, _
	ByRef mventry As MVEntry, _
	ByVal csattr As String, _
	ByVal mvattr As String)

	If csentry(csattr).IsPresent Then
		If Not csentry(csattr).Values.Count = 0 Then
			mventry(mvattr).Values = csentry(csattr).Values
		End If
	End If
End Sub
