Hi, slapd doesn't call chdir after/before doing chroot -> leaves cwd outside of chroot. This bug is still in openldap-2.0.6 but should be fixed in future versions. (The bug is in openldap-2.0.4/servers/slapd/main.c LINE 304) -Jarno
It appears that OpenLDAP 2.0.7 will be released within the next week or so. If it's not fixed then, I'll go ahead and patch the local copy.
I've added a patch to openldap-2.0.6-4, though 2.0.7 will almost certainly make it a duplication of effort.
