Description:

    Routine to issue new license to hydra client based on product requested, 
    it returns existing license if client already has a license and the 
    license is not expired/returned/revoked, if request product has not been 
    installed, it will issue a temporary license, if license found is temporary 
    or expired, it will tried to upgrade/re-issue a new license with latest 
    version of requested product, if the existing license is temporary and 
    no license can be issued, it returns LSERVER_E_LICENSE_EXPIRED

Description:

    Update an old license.  Behavior varies depending on product requested,
    the old license, and input support flags.

    *pdwSupportFlags == 0:
        it returns existing license if client already has a current-version
        license and the license is not expired/returned/revoked. if requested
        product has not been installed, it will issue a temporary license (if
        the client doesn't already have one). if old license is temporary
        or expired, it will try to upgrade/re-issue a new license
        with latest version of requested product. if the existing license is
        temporary and no license can be issued, it returns
        LSERVER_E_LICENSE_EXPIRED

    *pdwSupportFlags & SUPPORT_PER_SEAT_POST_LOGON:
        For non-per-seat licenses, it behaves as if the flag wasn't set.
        For per-seat licenses, if the old license isn't current-version
        temporary, it also behaves as if the flag wasn't set.
        Otherwise, it checks that the temporary license was marked as having
        been authenticated.  If so, it tries to issue a permanent license.
        If a license can't be issued, or if he temporary license wasn't marked,
        it returns the old license.

Arguments:

    phContext - client context handle.
    pdwSupportFlags - on input, abilities supported by TS.  on output,
                      abilities supported by both TS and LS
    pRequest - product license request.
    ChallengeContext - client challenge context handle, return from 
                       call TLSRpcIssuePlatformChallenge()
    cbChallengeResponse - size of the client's response to license server's
                          platform challenge.
    pbChallenge - client's response to license server's platform challenge
    cbOldLicense - size of old license.
    pbOldLicense - old license
    dwQuantity - number of licenses to allocate
    pcbNewLicense - size of return license.
    ppbNewLicense - return license, could be old license

Return Value:  

    LSERVER_S_SUCCESS
    TLS_E_INTERNAL
    LSERVER_E_INTERNAL_ERROR
    LSERVER_E_INVALID_DATA      old license is invalid.
    LSERVER_E_NO_LICENSE        no available license
    LSERVER_E_NO_PRODUCT        request product not install in current server.
    LSERVER_E_CORRUPT_DATABASE  Corrupted database.
    LSERVER_E_LICENSE_REJECTED  License request rejected by cert. server.

Abstract:

    Private routine to issue certificate to Terminal Server.

Parameter:

    phContext : Client context handle.
    pRequest : Terminal Server specific certificate request.
    pcbChallengeData : size of Server randomly generated challenge data 
                       to Terminal Server.
    ppbChallengeData : Server randomly generated challenge data to Terminal
                       server.

    pdwErrCode : Error code.

Returns:

    Function always return RPC_S_OK, actual error code is returned in
    pdwErrCode.

Note:

    Routine does not actually issue a license to Terminal Server, Terminal
    Server must call TLSRpcRetrieveTermServCert() to retrieve its own 
    license.

Abstract:

    Private routine to retrieve Terminal Server's license.

Parameters:

    phContext : client context handle.
    cbResponseData : size of Terminal Server responses data to 
                     license server's challenge.
    pbResponseData : Terminal Server responses data to license 
                     server's challenge.
    pcbCert : Size of Terminal Server's license in bytes.
    ppbCert : Terminal Server's license.
