This attribute is maintained by the DC on user and computer objects. The attribute contains a list of computer objects, corresponding to the RODCs at which the user or computer has authenticated. This attribute is a forward link attribute whose corresponding back link is the msDS-AuthenticatedToAccountlist attribute (see section 18.104.22.168.2). When a writable DC authenticates a user or computer to an RODC, that writable DC adds the DN of the RODC's computer object to the list in the msDS-AuthenticatedAtDC attribute of the user or computer that was authenticated.
This attribute was first maintained by DCs running Windows Server 2008 operating system.
