I got the impression that he was asking about the maximum object size.
I don't know if there is a limit in Zope itself, but I've run into
problems with PloneExFile when uploading files larger than about 25 MB.
Who knows - it might be a bug in PloneExFile, AttachmentField, or
Archetypes.  I lack the expertise required to troubleshoot the error, so
take this with the proverbial grain of salt.

BTW: I'm using LDAPUserFolder in a 10,000-user Active Directory
environment.  It works great.

Best wishes,
Matthew
