How to: Handle Many Connector Space Objects to One Metaverse Object in the Same Management Agent
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.
