Hi all, I think the time has come to bite the bullet and change our authentication engine to work in line with Zope 2.2 and above. UserDB-1.2 seems to have some problems with it (see my message today), and frankly, I haven't got the time to try and figure out why. Another point against UserDB is that it's not being developed any more. Ah well, it did the job for a long time.... Can anyone who's using an SQL based authentication system with Zope 2.2 successfully please let me know which one you used and how you did it? ta muchly, 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
