New subject: LDAP Verify Credentials operation

3 Jan 2011


      Ando and I have been discussing off-list the need for this op's request and response to carry additional fields.  The discussion started with a separate error code to distinguish errors which might be communicated back to authenticating entity (as opposed to the LDAP client submitting the VC request).
My current proposal is:
/*
 * LDAP Verify Credentials operation
 *
 * The request is an extended request with OID 1.3.6.1.4.1.4203.666.6.5 with value of
 * the BER encoding of:
 *
 * VCRequest ::= SEQUENCE {
 *      cookie [0] OCTET STRING OPTIONAL,
 *      name    LDAPDN,
 *      authentication  AuthenticationChoice
 *      controls [3] Controls OPTIONAL
 * }
 *
 * where LDAPDN, AuthenticationChoice, and Controls are as defined in RFC 4511.
 *
 * The response is an extended response with no OID and a value of the BER encoding of
 *
 * VCResponse ::= SEQUENCE {
 *      resultCode ResultCode,
 *      diagnosticMessage LDAPString,
 *      cookie [0] OCTET STRING OPTIONAL,
 *      serverSaslCreds [1] OCTET STRING OPTIONAL
 *      authzid [2] OCTET STRING OPTIONAL
 *      controls [3] Controls OPTIONAL
 * }
 *
 * where ResultCode is the result code enumeration from RFC 4511, and LDAPString and Controls are as
 * defined in RFC 4511.
 */
The use of controls here is to allow both the request/return of password policy information to the authenticating entity (as opposed those used on the extended operation itself to request/return password policy information about the LDAP client submitting the VC request).
