OK, I fixed my access problem.  Now, if I log in as user A and do 'lam *'

I see the entire hierarchy for A and they are all in the form

A/m1/m2/m3    A  lrswipcda

as it should be.

If I login as cyrus and do 'lam *'  I see

user/A/m1/m2/m3  default A lrswipcda
...
user/B/b1/b2     default B lrswipcda
...

Again, this is what I expect. BUT I DON'T see any indicator that B has
access to A.

But when I login as 'B' and do 'lam *'  I get

B/b1/b2     default B lrswipcda
...
A/m1/m2/m3  default A lrswipcda
...


It's clear that B has access to A but so far my efforts to deny access to
B seem to be failing.  Both as A and as cyrus I've tried forms of `sam A/*
B none` without success.
