This is a problem that has dogged us for ages, and this is probably the third time we've asked for help here. Basically, new users added to specific folders within Zope (via the acl_users folder) cannot login to the system. The only account that seems to work fine is the one for the 'admin' user. The most annoying thing about this is that it *did* work when we first installed Zope, but somewhere down the line it stopped. This has happened on two different servers with two different operating systems (Sun SOlaris and now Linux) and two different versions of Zope (2.4.1 and 2.4.3). It's a fairly serious problem if we want to use Zope to handle our main web site in the future. Anyone had this and solved it? Does v2.5 have this as well? Richard H.
