Re: SDK: ldap_simple_bind gives Protocol error

I think that still Binds with LDAP version 2, which the server
may be rejecting. Try to set LDAP version 3 first:
int protocol = LDAP_VERSION3;
ldap_set_option( NULL, LDAP_OPT_PROTOCOL_VERSION, &protocol );

That only prints a textual representation fo the error code. It does
not print the diagnosticMessage which the server may have enclosed to
answer your question. Try ldap_perror(ld, "Bind failed");
ldap_perror is deprecated, but it's by far the simplest way. An
alternative is ldap_get_option( ld, LDAP_OPT_DIAGNOSTIC_MESSAGE, &msg );
followed by printing and ldap_memfree()ing the message. Or async Bind,
then print and free the messages from ldap_parse_result().
