I've come accross this bug a couple of times, but it's hard to reproduce. AFAIK the may bug appear when I boot the machine. Distro: SuSE 7.0 with db-3.2.9 & SASL 1.5.24 (Login & Plain mech). Cyrus use pam for authentication Problem: No user/admin is able to authenticate. Nothing shows up in the log files. Restarting Cyrus resolvs the problem. -- Ørnulf Nielsen
