ACL calendar group question

Hi all,

I have a group called Default with all user in it. I have about 10 other
groups that constitute departments in our organization. I have setup the ACL
for calendar usage in the group Default so that the group Default and all
the 10 other groups are marked as ‘Read’. The 10 other groups have nothing
specific set for the calendar ACL’s.

I would expect that each user on the system that is part of Default would
then have a listing in the calendar pull-down menu ‘Select a user’ of each
of my ‘Read’ marked 10 groups? I don’t see this, I see only the Default
group and only the other groups that the user is a member of.

What am I doing wrong?

Thanks,
erics
