QUERYCLIENTCERT callback function
The QUERYCLIENTCERT function is a client-side function that enables the server to request a certificate from the client when establishing a Secure Sockets Layer (SSL) connection.
BOOLEAN _cdecl QUERYCLIENTCERT( _In_ PLDAP Connection, _In_ PSecPkgContext_IssuerListInfoEx trusted_CAs, _Inout_ PCCERT_CONTEXT *ppCertificate );
- Connection [in]
The session handle.
- trusted_CAs [in]
A list of server-trusted Certificate Authorities.
- ppCertificate [in, out]
Upon receiving the callback, the user supplies an appropriate client certificate in CERT_CONTEXT format and returns a value of TRUE. If the client cannot supply an appropriate certificate or wants the server to use anonymous credentials, it should return a value of FALSE instead. Any certificate supplied must be freed by the application after the connection is completed.
Implement this function in your client application with the signature previously described. Then call ldap_set_option (conn, LDAP_OPT_CLIENT_CERTIFICATE, &CertRoutine) where CertRoutine is the address of your callback routine.
When the server demands a client certificate for authorization it will call QUERYCLIENTCERT. The LDAP run time passes a structure containing a list of server-trusted Certificate Authorities. The client application must examine this list of CAs the server trusts and supply an appropriate client certificate. The run time subsequently passes these credentials back to the SSL server as part of the handshake. If the client application requires anonymous credentials, it should pass back FALSE instead of supplying a certificate.
