Hi again
I'm still trying to put the ldap server in a chroot jail.
I've created all files on the jail
$ ls
bin dev etc home lib tmp usr var
and copied there all libraries, all binaries, all config files, all schemas
(there is a list of the files at the end of this mail). But when I try to
start slapd with "-r /home/slapd" it still gives "error loading ucdata (error
-127)" (full log at the end of the mail)
My config file (I'm sure it's reading /home/slapd/etc/ldap/slapd.conf) is a
default debian config file, with
modulepath /usr/lib/ldap
moduleload back_bdb
and the main database
database bdb
suffix "dc=mydomain,dc=com"
directory "/var/lib/ldap"
Does anyone know what I'm doing wrong, or where should I look to find the
solution? I've found nothing about jailing slapd :(
Thanks in advance
