Thanks for all. Problem solved. I was create database from mail "[horde] short summary on IMP & HORDE with interbase" from "Alexander Knauer". All is right, in this mail, but in HORDE_PREFS table horde don't use name for field in table "UID" but "PREFS_UID" and "PREFS_SCOPE" instead "SCOPE". Zdenek Havel
