Hi,
Today I began to move my LDAP-Server to a Linux VServer jail. On the host and on the VServer I run Debian etch 4.0. Installing slapd was no problem (aptitude install slapd). I just copied all configuration and data files from the host which worked perfectly before and copied them 1:1 into the VServer.
slapd starts without any warnings. But connecting with a client is not possible, neither inside the VServer nor outside.
Please show the slapd debug logs when running with "-d -1" for these connection attempts.
Hi,
Thank you for your quick answer!
This is the output (after startup-output) when connecting via SSL:

Normally, slapd is started with:
/usr/sbin/slapd -h ldaps:/// ldap:/// -g openldap -u openldap -4
(In Debian with /etc/init.d/slapd, this is from ps aux).
Now I started with
slapd -h ldaps:/// ldap:/// -g openldap -u openldap -4 -d -1
But now I noticed also one very interesting thing: Starting slapd as root makes everything work fine!
/usr/sbin/slapd -h ldaps:/// ldap:/// -4
But it would be very great if I could start slapd as "openldap" for security reasons!
Also give the actual version numbers of the OpenLDAP software in use, and your SSL library. I have no idea what Debian bundles in their releases.
