It seems like my ldapsearch can't find the get local issuer certificate. what configuration files tells the ldapsearch of which certificate to use? Oh, my certificate and keys and cacert files are good, I've tested them using the openssl s_server and s_client to get a basic connection. can someone help me, I don't know what else could be the problem.
I could be way out, but it seems to me from both your client and server logs that your certs haven't been generated correctly. AFAICS you've given the correct cert locations in your two OpenLDAP config files.
Your certs must be in pem format, not in der format.
Try the following on your server cert:
openssl x509 -in nameofyourcert -noout -text | less Look for: X509v3 Authority Key Identifier: keyid:9C:47:70:97:DE:A3:FA:23:6F:58:57:C7:97:99:B7:DD:02:2E:A8:64 (This is from one of my own certs, so the keyid won't be the same) DirName:/C=NL/ST=Noordholland/O=Barlaeus etc.
Do the same on your CA cert and verify that you have something like: X509v3 Subject Key Identifier: 9C:47:70:97:DE:A3:FA:23:6F:58:57:C7:97:99:B7:DD:02:2E:A8:64 X509v3 Authority Key Identifier: keyid:9C:47:70:97:DE:A3:FA:23:6F:58:57:C7:97:99:B7:DD:02:2E:A8:64 (i.e. the same keyid as in the server cert) DirName:/C=NL/ST=Noordholland/O=Barlaeus etc.
This should show that the server cert has been signed by the CA for which the CA cert has been presented to both server and client.
Best,

Hi, I'm having some troubles with openldap w/ TLS. I can't seem to do a ldapsearch -x -LLL -ZZ, as it is giving be back "SSL3_GET_SERVER_CERTIFICATE:certificate verify failed" On the server side log I'm getting: 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
I've tried and tested my ssl connection using: openssl s_client -connect ldap1.mylan:636 -showcerts -state -CAfile /usr/local/etc/openldap/cacert.pem and that works, althought if I use "TLSVerifyClient demand" in slapd.conf, the server will reject the connection saying that the client didn't send the certificate.
I also tried the client authentication ssl test and the works w/ and w/o the TLSVerifyClient demand option: openssl s_client -connect ldap1.mylan:636 -state \ -CAfile /usr/local/etc/openldap/cacert.pem \ -cert /usr/local/etc/openldap/slapd-cert-ldap1.pem \ -key /usr/local/etc/openldap/slapd-key-ldap1.pem
