Hello both,
Finally I compiled and linked all binaries so that they can be found in the path before the installed ones. In the ldap.conf file for the client I set TLS_CACERT to the certificate that I create for the client in the server and it worked. So, now ldapsearch does work, but looks like the local auth system is unable to query for users... when I set the authconfig, the server says:
slap_listener(ldaps://curri0.imppc.local:636)
connection_get(12): got connid=1097 (this number keeps growing) connection_read(12): checking for input on id=1097 TLS trace: SSL_accept:before/accept initialization TLS: can't accept: (unknown). connection_read(12): TLS accept failure error=-1 id=1097, closing connection_close: conn=1097 sd=12
many times. Without TLS it did work before, also it has something to do with the new installation of the openldap... Thanks for all your help, j

If you are using /usr/bin/ldapsearch on Fedora 14 and later, it is linked with Mozilla NSS instead of openssl. But openldap with moznss works the same as it does with openssl.
so certificates generated by openssl should work with this settings?
Yes.
Do you have your CA cert on the client machine?
I copied the ca-cert.pem from the server machine to the client,
Ok.
along with the certificate that I generate for the client itself.
Not sure what you mean by this.
I created a certificate for the client, signed by the server, I thought that the procedure of the certificate file wasn't only about creating a ca-cert.pem file and propagate it trought all clients, but create a certificate for each client signed by the same ca-cert. I don't know if I made myself clear, I followed (between others) this howto: http://www.openldap.org/pub/ksoper/OpenLDAP_TLS.html look at pint 4.3, it creates a certificate file for each client, isn't it? maybe i didn't understand it quite well
Yes. Looks like it creates client (i.e user) certificates.
I'm not sure what the problem is. If you think the problem is with moznss, find an ldapsearch client built with openssl (Fedora 13 or earlier if you have access).
I thought that it was this last certificate the one that I should place in the TLS_CACERT (ldap.conf) not the general one.
Not sure what you mean by this. TLS_CACERT must be the certificate of the CA that issued the server cert.
If so, did you specify it in /etc/openldap/ldap.conf or ~/.ldaprc? If not, you can also specify it on the command line like this:
LDAPTLS_CACERT=/path/to/ca_cert.pem ldapsearch -x -H ldaps://curri0.imppc.local:636/
I made the test and still it does not work ;( # LDAPTLS_CACERT=/etc/openldap/cacerts/ca-cert.pem ldapsearch -x -H ldaps://curri0.imppc.local:636/ -d 1 ldap_url_parse_ext(ldaps://curri0.imppc.local:636/) ldap_create ldap_url_parse_ext(ldaps://curri0.imppc.local:636/??base) ldap_sasl_bind ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP curri0.imppc.local:636 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying 172.19.5.13:636 ldap_pvt_connect: fd: 3 tm: -1 async: 0 TLS certificate verification: subject: -unknown-, issuer: -unknown-, cipher: -unknown-, security level: off, secret key bits: 0, total key bits: 0, cache hits: 0, cache misses: 0, cache not reusable: 0 TLS certificate verification: bad TLS certificate verification: Error, -8182: Unknown code ___f 10 TLS: error: connect - force handshake failure -1 - error -8182:Unknown code ___f 10 TLS: can't connect: . ldap_err2string ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)
It seems that it doesn't like the certificate.
-8182 is SEC_ERROR_BAD_SIGNATURE. During the TLS/SSL handshake, the client tries to see if the server's cert is correctly signed by the CA cert (the local ca-cert.pem).
the server says:
slap_listener_activate(8):
slap_listener(ldaps://curri0.imppc.local:636)

I assure you that both ca-cert.pem files from server and client are the sames, as I create it and send it throught scp.. j
