    17  * This is an implementation of NTLM authentication that does single-signon

    18  * by obtaining the user's Unix username, parsing it into DOMAIN\name format,

    19  * and then asking Samba's ntlm_auth tool to do the authentication for us

    20  * using the user's password cached in winbindd, if available. If the

    21  * password is not available then this component fails to instantiate so

    22  * nsHttpNTLMAuth will fall back to a different NTLM implementation.

    23  * NOTE: at time of writing, this requires patches to be added to the stock

    24  * Samba winbindd and ntlm_auth!
