I'm looking for a way to set group membership in Active directory when
syncing from our IDVAULT

We do not sync group information in the driver itself, so when a user is
created/migrated they simply become a member of 'Domain Users.

However, we have one group in AD that we require all users to be a member of
by default, but I have tried to use 'add destination attribute value' and
this does not seem to work.

Do I have to make the user a member of the group and also make the group
have the user as a member?

Any thoughts?
