Login nach Kennwort Änderung nicht mehr möglich

[dfricke]

Nachdem das Kennwort durch den User geändert wurde, ist der Login über das Webfrontend zwar möglich, aber es funktioniert das E-Mail Modul nicht mehr. Des Weiteren funktioniert ActiveSync nicht. Dort gibt es die Fehlermeldung, dass das Kennwort falsch sei.
Das Problem verschwindet nach ca. 4-6 Stunden. Als Betriebssystem wird UCS 3.2 verwendet. Es gibt folgenden Traceback in der Listener.log
