RE: TLS bare minimum

ok so I've learned a little bit more about ldapsearch
on the server running TLS I can use the -ZZ directive and connect
then next thing I did was to try and connect from a different machine using -ZZ
with this command
ldapsearch -ZZ -x -h serveraddress -v -b 'uid=tester,ou=People,dc=test,dc=com'
this results in the following output
ldap_start_tls: Connect error (-11)
        additional info: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

ok fine, that is correct, it does not have the CA cert to use, I tried to copy the CAcert from the Ldap server but I still get the same error

I think you need to seriously examine running modern, supported versions of 
OpenLDAP (2.3.35 is the current release).  But no, you don't need a client 
cert to establish TLS.  The client must have access to the CA that signed 
the server cert, however.  Have you read the man page on ldapsearch?  Do 
you have any example of how you are using ldapsearch?
