Our requirement is that we need to test if a server certificate on Openldap server is valid and then upload to our trust store and use the certificate for further communications using SSL to the ldap server.
I configured Openldap for SSL as per the Openldap admin guide - generated the 3 certificates cacert.pem,servercert.pem and serverkey.pem and put the corresponding entries in slapd.conf file. My assumption is cacert.pem is the file for the CA,servercert.pem is the server certificate file(?!) and the serverkey.pem is the file containing the private key to the server. After configuring my client ldap.conf file to point to cacert.pem as per the following directives -

TLS_CACERTDIR <path to my cacert.pem file>
TLS_REQCERT hard

I was able to execute a ldapsearch successfully. My problem is that after adding cacert.pem to my truststore, I am unable to use the certificate in java using SSL. I get the following exception -

I googled for the above exception and from what I got, I thought I had to configure for a client certificate. I am not sure I am following the procedure correctly. My question is -
Is servercert.pem the file that I need to use as server certificate. How can I validate it? (Pointing to this file in ldap.conf gave me an error) Is there some other directive in ldap.conf file which points to this file ( I thought only 3 valid directives are present TLS_CACERTDIR,TLS_CACERT,TLS_REQCERT.
Thanks
