Hi Nick,
it took me some time to set up TLS successfully, so I'm with
you in this journey ;-)
From my own experience, I would suggest to start verfifying
the
server first. Let the client simply have the
TLS_CACERT /<path>/<to>/<cachain>/cacert.chain.pem
TLS_REQCERT demand
options set and not send any certificate at all.
On the server's side, only set
TLSCertificateFile /your/cert.pem
TLSCertificateKeyFile /your/private/key.pem
You will not need a CACert file on the server for now.
Make sure that the client will not send any certificate, so
check your current users .ldaprc, because the client certificate
depends on the user that runs the ldapsearch command.
If you can set up TLS this way, you can be sure that the
server is valid. To validate your client, you will need
a .ldaprc in the current user's home directory which points
to the user's cert and key. The server must be able to
verify the user's cert.
Hope, this helps,
Hauke

Betreff: openldap and TLS certificates
Hello everyone,
I seem to have a problem with setting up secure connections with my
LDAP server. I believe the problem has mainly to do with my certificates
rather than anything else. I used the tutorial provided by the openLDAP
admin guide to generate my certificates
http://damncoolpics.blogspot.com/2008/09/oktoberfest-2008-in-munich.html
My slapd.conf files has the following entries
#SSL/TLS Options
TLSCipherSuite HIGH:MEDIUM
TLSCACertificateFile /usr/local/etc/slapd-cacert.pem
TLSCertificateFile /usr/local/etc/slapd-cert.pem
TLSCertificateKeyFile /usr/local/etc/slapd-key.pem
and my ldap.conf
TLS_CACERTDIR /etc/openldap/cacerts
TLS_CACERT /etc/openldap/cacerts/slapd-cert.pem
slapd-cacert.pem is the certificate of the CA
slapd-cert.pem is the server certificate (same copy on client and
server)
slapd-key.pem is the server key (I manually removed the certificate
request that was generated by the process on the link above)
I start the server using /usr/local/libexec/slapd -h ldap:/// ( also
tried the -d 9 flag for debugging), and when I use ldapsearch I get the
following errors
(from the client)
ldapsearch -x -ZZ (I have most of the settings in my ldap.conf)
ldap_start_tls: Connect error (-11)
additional info: error:14090086:SSL
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
(from the server with the -d 9 flag)
I get load of stuff, but the important seems to be the following
TLS trace: SSL3 alert read:fatal:unknown CA
TLS trace: SSL_accept:failed in SSLv3 read client certificate A
TLS: can't accept.
TLS: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca
s3_pkt.c:1053
connection_read(12): TLS accept failure error=-1 id=0, closing
When I try a search without the -ZZ flag everything works fine. When I
created the certificates I tried different common names. I tried the ip
address, fully qualified name (as shown below), the short name, even my
name, but no luck. I have read the proper RFC but could not get
anyusefull information. By the way I have a local DNS server and the
domain name should match the correct IP address (and the reverse).
Truth is I do not know much about SSL and certificates, so I might be
missing something. Just for your information, The certificate authority
is the same with the LDAP server. I will provide the certificate below,
with email and addresses altered. Also the hashes have been altered so
key and cert will not match. I merely provide them just in case you see
something wrong in the syntax.

Hello again,
I followed your instructions, and I keep getting the same errors. I
have also tried to remove the entries before the actual certificate and
still no change. There was another suggestion on generating the
certificates. I will try that and hope for the best.
Thanks for the help
Nick

Hi Nick,
it took me some time to set up TLS successfully, so I'm with
you in this journey ;-)
>From my own experience, I would suggest to start verfifying
the server first. Let the client simply have the
TLS_CACERT /<path>/<to>/<cachain>/cacert.chain.pem
TLS_REQCERT demand
options set and not send any certificate at all.
On the server's side, only set
TLSCertificateFile /your/cert.pem
TLSCertificateKeyFile /your/private/key.pem
You will not need a CACert file on the server for now.
Make sure that the client will not send any certificate, so
check your current users .ldaprc, because the client certificate
depends on the user that runs the ldapsearch command.
If you can set up TLS this way, you can be sure that the
server is valid. To validate your client, you will need
a .ldaprc in the current user's home directory which points
to the user's cert and key. The server must be able to
verify the user's cert.
Hope, this helps,
Hauke

Betreff: openldap and TLS certificates
Hello everyone,
I seem to have a problem with setting up secure connections with my
LDAP server. I believe the problem has mainly to do with my certificates
rather than anything else. I used the tutorial provided by the openLDAP
admin guide to generate my certificates
http://damncoolpics.blogspot.com/2008/09/oktoberfest-2008-in-munich.html
My slapd.conf files has the following entries
#SSL/TLS Options
TLSCipherSuite HIGH:MEDIUM
TLSCACertificateFile /usr/local/etc/slapd-cacert.pem
TLSCertificateFile /usr/local/etc/slapd-cert.pem
TLSCertificateKeyFile /usr/local/etc/slapd-key.pem
and my ldap.conf
TLS_CACERTDIR /etc/openldap/cacerts
TLS_CACERT /etc/openldap/cacerts/slapd-cert.pem
slapd-cacert.pem is the certificate of the CA
slapd-cert.pem is the server certificate (same copy on client and
server)
slapd-key.pem is the server key (I manually removed the certificate
request that was generated by the process on the link above)
I start the server using /usr/local/libexec/slapd -h ldap:/// ( also
tried the -d 9 flag for debugging), and when I use ldapsearch I get the
following errors
(from the client)
ldapsearch -x -ZZ (I have most of the settings in my ldap.conf)
ldap_start_tls: Connect error (-11)
additional info: error:14090086:SSL
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
(from the server with the -d 9 flag)
I get load of stuff, but the important seems to be the following
TLS trace: SSL3 alert read:fatal:unknown CA
TLS trace: SSL_accept:failed in SSLv3 read client certificate A
TLS: can't accept.
TLS: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca
s3_pkt.c:1053
connection_read(12): TLS accept failure error=-1 id=0, closing
When I try a search without the -ZZ flag everything works fine. When I
created the certificates I tried different common names. I tried the ip
address, fully qualified name (as shown below), the short name, even my
name, but no luck. I have read the proper RFC but could not get
anyusefull information. By the way I have a local DNS server and the
domain name should match the correct IP address (and the reverse).
Truth is I do not know much about SSL and certificates, so I might be
missing something. Just for your information, The certificate authority
is the same with the LDAP server. I will provide the certificate below,
with email and addresses altered. Also the hashes have been altered so
key and cert will not match. I merely provide them just in case you see
something wrong in the syntax.
The server certificate
