Hello,
Is there a unit tester where the client LDAP_OPT_X_TLS_REQUIRE_CERT option is
set to LDAP_OPT_X_TLS_NEVER that I can try? I was looking at
openldap-2.4.44/clients/tools/ldapsearch but it doesn't configure this option.
My application program sets LDAP_OPT_X_TLS_NEVER. Why does LDAP client still
check for server certificate which fails in the case of bad certificate?
int opt;
opt = LDAP_OPT_X_TLS_NEVER;
ldap_retcode = ldap_set_option(m_tLDAP, LDAP_OPT_X_TLS_REQUIRE_CERT, &opt);
...

Subject: RE: Using TLS
I rebuilt with libssl (an OpenSSL library which supports SSL and TLS) and that
worked. Thanks.
However, I got into the connect error "14090086:SSL
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed (self signed
certificate)", even though the LDAP_OPT_X_TLS_REQUIRE_CERT option is set to
LDAP_OPT_X_TLS_NEVER. Isn't LDAP client supposed to bypass server certificate
validation when LDAP_OPT_X_TLS_NEVER is configured?

If your ldap libs are linked to gnutls, then it might be worthwhile to rebuild
and link to the openssl library; then test your code again.
I don't use gnutls because it has given me problems.
