Run slapadd as the same user that slapd runs as.  This is no different than running slapadd without shared memory segments, where you will have the same issue with the created BDB caching files (i.e., same results whether it is in memory or on disk).

Thanks, yes you are right. This issue I've never seen on my server, because SuSE automatically makes automaticly (via start script) a chown in the different backend database directorys ...

Thanks Steeg
