Hello all,
I hope someone could help me -- I'm trying for almost one whole day already and couldn't get LDAP over SSL to work, without success.
The objective is to setup a development box for testing purposes, so, the simpler the better, however, it must be as simple as needed only.
I've followed this tutorial: http://islandlinux.org/howto/installing-secure-ldap-openldap-ssl-ubuntu-using-self-signed-certificate. I'm on Mac OSX Snow Leopard, though.
slapd version: @(#) $OpenLDAP: slapd 2.4.11 (Feb 11 2010 02:23:14) //Installed from MacPorts
I have generated a self-signed certificate using this command:
sudo openssl req -newkey rsa:1024 -x509 -nodes -out server.pem
-keyout server.pem -days 3650
I've set the Common Name to "localhost".
The configuration files look like this (non-relevanted parts snipped):
slapd.conf:
TLSCipherSuite HIGH:MEDIUM:-SSLv2
TLSCACertificateFile /Users/myuser/Sandbox/server.pem
TLSCertificateFile /Users/myuser/Sandbox/server.pem
TLSCertificateKeyFile /Users/myuser/Sandbox/server.pem
TLSVerifyUser never
ldap.conf
BASE dc=mycompany,dc=com
URI ldaps://localhost/
TLS_REQCERT never
I'm starting slapd with the following command:
sudo /usr/libexec/slapd -f /opt/local/etc/openldap/slapd.conf -d1 -h "ldaps:///"
And testing the connection with the following:
ldapsearch -H ldaps://localhost -d255
When running ldapsearch, I get the following as output:
ldap_create
ldap_url_parse_ext(ldaps://localhost)
ldap_pvt_sasl_getmech
ldap_search

put_filter: simple

TLS: can't connect.

ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1)
As you can see, it fails with the "TLS: can't connect" error message. Not that obvious. I then switch to the terminal that has slapd running on the fg, and I see the following:
(snip)
connection_get(13): got connid=0
connection_read(13): checking for input on id=0
connection_read(13): TLS accept failure error=-1 id=0, closing
connection_closing: readying conn=0 sd=13 for close
connection_close: conn=0 sd=13
What I don't understand is why it is failing if I've set both sides to ignore certificates. What am I doing wrong?
