Right, ldap_set_option doesn't take string input argument. I implied an integer value such as LDAP_OPT_X_TLS_NEVER, LDAP_OPT_X_TLS_ALLOW, etc. I have no doubt it works nicely in your case. Just trying to understand why it doesn't on my side.
Hard to say without the full context of your code. It clearly works not just with what I did, but with other client code as well, whether it's the bits that part ldap.conf/.ldaprc to the syncrepl client code, etc.
