procedure ResolveNameConflict(
   replEntinfList: REPLENTINFLIST,
   parentObject: DSName,
   var attributesAndStamps: set of AttributeAndStamp): DN

Informative summary of behavior: The ResolveNameConflict procedure checks whether there is a name conflict (see [MS-ADTS] section 3.1.1) while applying a replicated update. If there is a name conflict, the procedure changes the desired DN of the object for which the replicated update is applied, or changes the DN of the existing object so that there is no name conflict. Following are the input parameters for this procedure:

replEntinfList: The update to be applied.

parentObject: The DSName of the parent object.

attributesAndStamps: The AttributeAndStamp set that corresponds to the replicated update (can be modified by this procedure).

 objectDN: DN
 rdnValue: unicodestring
 duplicateObject: DSName
