i found my issue.  i had my user id defined as a sudo ID, and as a
member of the wheel group, which had sudo rules assigned to it.  because
the wheel group processed in the rules before my id, i got the access
granted to the wheel group, and the rest was "fall through" and
ineffective.  i have fixed the issue, and now get the proper behavior.
