Hi There,

I am using an ldap server created using unbounded ldap API (Java). And the server is started to support both ldap and ldaps. Sever uses java keystore (.jks) certificates namely 123keystore.jks and 456truststore.jks and some 789server.cer (all these files are protected by some passoword). The server is listening at port # 1636 for all ldaps connections.

I am able to connect to the server using (ldaps) some java ldap clients and able to bind and search successfully. But when I try to connect to the server using openldap client, it is NOT working, getting SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed error.

I get the below error when I try to do the search using ldaps://<ip>:1636

ldapsearch -w 'xxxxxx1234' -H ldaps://xx.xx.xx.xxx:1636 -b "o=person,o=hp" -D "id=xxxx89,o=person,o=hp"

[bea@devcg4sdmbl01 ldapsearch -w 'xxxxxx1234' -H ldaps://xx.xx.xx.xxx:1636 -b "o=person,o=hp" -D "id=xxxx89,o=person,o=hp"

Here is my ldap.conf : located at /etc/openldap/ldap.conf

URI ldaps://x.x.x.x:1636/

BASE o=person,o=hp

HOST <IP>

PORT 1636

#TLS_CACERT /etc/openldap/cacerts/123keystore.jks // server is started using jks certificates for secure connections.. this is not working

TLS_CACERT /etc/openldap/cacerts/789server.cer // This didn’t work

# TLS_CACERT /etc/openldap/cacerts/789server.pem // I converted the cer to pem file.. But even this didn’t work

TLS_CACERTDIR /etc/openldap/cacerts

TLS_REQCERT require

What is the correct configuration to make this work? Can I use the jks certificates in openldap client to connect to server which is using jks for ldaps connections? What is missing here? Pls help fix this issue.

Same openldap client works fine for non-secure and simple authentication ldap connections. The problem is only when I try to use ldaps from the client.

Thanks in advance. Let me know if you need more info.
