File: SetDetector.cpp
|
|
|
|
Comments: implementation of COM object to detect whether a set of users and
|
|
groups forms a closed set.
|
|
|
|
This is used by the GUI, and the engine to determine whether ReACLing must be
|
|
done for intra-forest, mixed-mode source domain, incremental migrations.
