Hello :)
Hopefully I'm not completly wrong on this ml, as its not only ldap
related, but also samba related.
I work at a Chair of a german university.
University uses a central LDAP-system for all students, employees,
scientists, scientific guests, etc., providing an unique UID for all
these peoples, plus many more information.
My idea was: setting-up a local OpenLDAP-proxy, so that people of our
Chair get access to ressources (eg. via samba) using their unique UID
and password, but without setting-up an AD.
Many system here are owned by the Chair or University, but lots of
students are using their own laptop, so using a AD (and adding them) is
not very handy for them ... so, something like a stand-alone
samba-server with authentification versus ldap.
Is there a chance to get this running? There is no chance to add the
schema on a proxy?
What I did so far:
- I can establish a connection to the central LDAP-system using
/etc/pam_ldap.conf
uri ldaps://ldap.DOMAIN.de
host ldap.DOMAIN.de
base ou=CHAIR,ou=hosts,dc=DOMAIN,dc=de
ldap_version 3
binddn cn=CHAIRCODE,ou=SECURITY,dc=DOMAIN,dc=de
bindpw PASSWORD
pam_password crypt
ssl start_tls
ssl on
- I configured /etc/libnss-ldap.conf, and a 'getent passwd' shows all
local users plus the members
uri ldaps://ldap.DOMAIN.de
host ldap.DOMAIN.de
base ou=CHAIR,ou=hosts,dc=DOMAIN,dc=de
ldap_version 3
binddn cn=CHAIRCODE,ou=SECURITY,dc=DOMAIN,dc=de
bindpw PASSWORD
- I also configured /etc/ldap/slapd.conf for proxy usage (I think I did
...), but I learned 2 days ago I can't add any schemata on a proxy ...

Testing the config works:
root@ldap:~# /usr/sbin/slapd -Tt -f /etc/ldap/slapd.conf
config file testing succeeded
62398f56 mdb_opinfo_get: err Permission denied(13)
root@ldap:~#
(I have no idea which Permission is denied)
slapd can be started via
/usr/sbin/slapd -g openldap -u openldap -f /etc/ldap/slapd.conf
ldapsearch works fine using '-h localhost' or '-H
ldap://ldap.DOMAIN.de', so I think the basic config is not bad at all ...
Thanks in advance!
Cheers,
Torsten
