So say I had two GCV's

Users set to cn=users,
AD-Domain set to dc=acme,dc=corp

Could I in the IF condition for SourceDN, in subtree test, specify:
~Users~~AD-Domain~

and have that work? I.e. Build the string via GCV's?

If that does work, could I use a comma in between?

~Users~,~AD-Domain~

So that my Users GCV would not need the trailing comma?

Ya, I know, i could store it all in one GCV, but this is for a multi-AD
environment, and I already have AD-Domain as a driver specific GCV set,
and I need to exclude the CN=Users container objects...

So I can set a DriverSet GCV once, of Users equal to "CN=users," and be
done. Instead of maintaining another GCV on all AD drivers.
