Hi all, Is there any more info on using UserDB to do cookie authentication available anywhere (I've tried the source, there's too much Zope Zen going on there for me). I want to be able to have anything up to 12,000 users authenticated and I get the impression that there will be a user icon made for each of them in the acl_users folder. Specifically, I don't seem to be able to logout (go back to being an anonymous user), and I'd like to embed the authentication form into my (currently non-authenticated) output if possible. TIA tone. ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project http://nle.ncl.ac.uk/ The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2
