Thanks. You're a genius. I struggled a lot, but think I finally managed to
get something working. I tried to follow the openldap faq at
http://www.openldap.org/faq/data/cache/185.html for creating CA
certificates, but my shell script is called CA not CA.sh.
I've done the following:
# cd /etc/pki/tls/misc/
# ./CA -newca
(filled in all prompted information, and gave it a pwd)
# openssl req -new -nodes -keyout newreq.pem -out newreq.pem
(filled in all prompted information)
# CA.sh -sign
# cp /etc/pki/CA/cacert.pem /etc/openssl/cacerts/
# cp newcert.pem /etc/openssl/ssl/servercrt.pem
# cp newreq.pem /etc/openssl/ssl/serverkey.pem
Then updated my slapd.conf to show:
Then updated /etc/ldap.conf to show:
Restart the slapd daemon
# service ldap restart
And I can finally get ldapsearch to work. Although I tried tls_cacertdir
for both /etc/ldap.conf and /etc/openldap/ldap.conf and it doesn't work for
some odd reason. Not sure why.
# ldapsearch -Z -x "(uid=eric)"
<returns the ldif entry for uid=eric>
So next test was to create a new user. luseradd foo works perfect. I find
it in my ldap tree as expected. All I had to do is modify the
create_modules and modules to specify ldap only (to avoid it modifying the
passwd and shadow files), and everything seems to be working.
Thanks for your help!
