# Description:
# Partial C706.pdf + [MS-RPCE] implementation
#
# Best way to learn how to use these calls is to grab the protocol standard
# so you understand what the call does, and then read the test case located
# at https://github.com/SecureAuthCorp/impacket/tree/master/tests/SMB_RPC
#
# ToDo:
# [ ] Take out all the security provider stuff out of here (e.g. RPC_C_AUTHN_WINNT)
# and put it elsewhere. This will make the coder cleaner and easier to add
# more SSP (e.g. NETLOGON)
