All messages are tamperproof and are not passed in clear text. Reserved for future use.

SECPKG_FLAG_TOKEN_ONLY

SECPKG_FLAG_ACCEPT_WIN32_NAME

Understands 32-bit Windows principal and target names.

SECPKG_FLAG_STREAM

Supports stream semantics.
wVersion

Version of the package protocol, which must be 1.

wRPCID

DCE RPC identifier, if appropriate. If the package does not implement one of the DCE-registered security systems, the reserved value SECPKG_ID_NONE is used.

cbMaxToken

Maximum size, in bytes, of the token.

Name

Pointer to a null-terminated string that contains the name of the security package.

Comment

Pointer to a null-terminated string, which can be any additional string passed back by the package.
