SYMPTOMS
While you are importing an object that has NTDSnoMatch stamped on an extension attribute, the Active Directory Connector (ADC) reports an event 8281 warning in the Application event log:

Event Type: Warning

Event Source: MSADC

Event Category: Replication

Event ID: 8281

Description:

ADC could not replicate the msExchMasterAccountSid to

CN=user,OU=MyOu,DC=Domain,DC=com because this sid

is already on the object CN=OtherUser,OU=MyOu,DC=Domain,DC=com.

(Connection Agreement '1 Way From 55' #3272)



CAUSE
This behavior occurs because the associated Microsoft Windows NT account on this object is already the Master Account Security ID (SID) on an object in the target directory.
