[ZOPE] using re.compile(...) raises an HTTP401 (basic authencication) ??????

PythonScript products in Zope run in a protected environment, similar to a
Bastion environment.
Basically, various things including attribute access is checked on the fly
and verified by a SecurityManager.

Your problem is that you are allowed to *import re* ... you're just not
allowed to do anything with it ;-)
ie  re.compile ends up calling __careful_get_attr(re, 'compile') and the
securityManager says "NO!!"

Check out the code in the PythonScript product if you want to see how this
stuff works.

Solutions ? Well, easiest is to create this as an External Python Script ...
they can do anything they like.
