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?

I am running zope 2.5.0 on Solaris (I had installed the binary version) using ZServer. I am able to access the web management interface with the initial user admin created at installation time. Later I had added a user "portal_manager", which could login without any problems. About one week later I couldn't login with this user but could still login with user admin. Restarting ZServer solved the problem. This is not a problem for a test site, but in a production environment we don't want to restart ZServer each time a user can't login. Dieter Maurer indicated this is due to some memory problems in older versions of zope.

All of a sudden, some "acl_users" objects went away.

Of course, login via these formerly existing user folders were no longer possible.

Restarting Zope solved the problem for some days. Then, the "acl_users" disappeared again.

Upgrading to Zope 2.5 *AND* Python 2.1.2 solved the problem... It was almost surely caused by the known memory corruption problems in Zope 2.4.x (with 1 <= x <= 3) and Python 2.1.1.

But I am using zope 2.5.0 and this problem might still exist. Is there a solution for this problem (without restarting Zserver) ? With kind regards, Juergen Berger
