class _EXPORT CComAuthInfo
/*++

Class Description:

    Server/authentication information.  Contains optional 
    impersonation parameters. Typically used in the construction in 
    CIISInterface.

Public Interface:

    CComAuthInfo            : Constructor.  Impersonation optional
    operator=               : Assignment operators
    CreateServerInfoStruct  : Helper function for use in COM
    FreeServerInfoStruct    : As above.

Notes:

    Because there's an operator for a pointer to itself and because
    CIISInterface copies the information at construction time, a 
    CComAuthInfo can safely be constructed on the stack as a parameter
    to CIISInterface derived classes.
