[Zope] acl_users versions?

[ghaley@mail.venaca.com]

hi folks,

i have been looking at several varieties of the acl_users folder, and
there seem to be three -- in one, there are three tabs, contents,
security, and undo; in the second, there are four tabs, contents,
properties, security, and undo; and in the third there are also four, but
these are contents, security, undo, and ownership.

the third is with a brand new install of zope 2.3, which i downloaded last
week and installed with no problems at all.  the other two varieties are
both found on the same server running the same version of zope, 2.1.6.

the reason i ask is that i have created a series of users in order to
provide management access to a very limited set of resources, separate
from the rest of the site.  when i go to the directory by pointing the
browser directly to it, i get a zope error that AUTHENTICATED_USER does
not exist due to a missing docLogin method.  so far the only way i
remember seeing docLogin method is in version # 2, under the properties.
the error trace points back to the role manager, but i changed some of
these for this folder, and still the same result.

i am really quite confused, as i have used this method quite successfully
in other folders in our site, and have not had this much trouble.  one
solution, though it would be kludgey would be to copy an acl_users folder
from one of the folders where it does work, but i would much rather find
out why it does work in one instance and why it doesn't in the other.

any pointers to appropriate howtos or documentation on this would be
greatly appreciated.  i have found that the details of the authentication
process are along the steepest and slipperiest parts of the learning curve
for zope.  i've read as much of the documentation on authenticating and
de-authenticating logins as i can find, and the basic orientation of the
parts to each other tend to be covered, but there is scarely anything on
the internal (like at the point of the core code) that actually explains
how the data are being passed and handled from the browser to the base.

anyway, sorry to sound like i'm whining.

ciao!
greg.
