[Samba] Does Samba/Winbind not follow nested groups in AD?!?

[James A. Dinkel]

Here's the situation:  We have users who are members of groups and those
groups are sometimes members of a 2nd level of groups.  If a folder has
permissions assigned to a 2nd level group, then the user can not access
the share.  Doing a "getent group | grep user | grep 2nd_level_group"
also returns nothing.  Samba seems to not be recognizing that a user is
a member of a group under another group.

Is there any way to enable Samba, or Winbind, to follow down the group
hierarchy?
