DCE Global Directory Agent
The DCE Global Directory Agent (GDA) is the third major component of the DCE Directory Service. It acts as an intermediary between the local cell's directory service and the global directory services. In particular, the GDA handles CDS calls that are directed to foreign cells. The foreign cells must be registered with one of the two global directory services that DCE supports - the X.500 Directory Service or the Domain Name Service.
