win32security: setting process privileges

Hi,

I'm trying to set process privileges in a thread that needs to call
win32security.LogonUser.

I need to enable

SE_TCB_NAME
SE_CHANGE_NOTIFY_NAME
SE_ASSIGNPRIMARYTOKEN_NAME

When I attempt to assign these privileges to the current thread, only
one assignment succeeds (SE_CHANGE_NOTIFY_NAME).  The MSDK win32 api
docs INDICATE that SE_CHANGE_NOTIFY_NAME is assigned by default.  The
following example is for SE_ASSIGNPRIMARYTOKEN_NAME.

>>>import win32security
>>>import ntsecuritycon
>>>import win32con
>>>import win32api
>>>
win32security.LookupPrivilegeValue(None,ntsecuritycon.SE_CHANGE_NOTIFY_NAME))

7
>>>
win32security.LookupPrivilegeValue(None,ntsecuritycon.SE_ASSIGNPRIMARYTOKEN_NAME)

23
>>>
win32security.LookupPrivilegeValue(None,ntsecuritycon.SE_ASSIGNPRIMARYTOKEN_NAME)

3
>>> flags=ntsecuritycon.TOKEN_ADJUST_PRIVILEGES |
ntsecuritycon.TOKEN_QUERY
>>> flags
40
>>>id=win32security.LookupPrivilegeValue(None,ntsecuritycon.SE_ASSIGNPRIMARYTOKEN_NAME)

>>> id
3
>>> nP=[(id,ntsecuritycon.SE_PRIVILEGE_ENABLED)]
>>> nP
[(3, 2)]
>>>
htoken=win32security.OpenProcessToken(win32api.GetCurrentProcess(),flags)

>>> htoken
268

>>> win32security.AdjustTokenPrivileges(htoken,0,nP)
Traceback (innermost last):
  File "<interactive input>", line 1, in ?
api_error: (1300, 'MyAdjustTokenPrivileges', 'Not all privileges
referenced are assigned to the caller.')
>>>

What privileges do I as a user need to be assigned, in order that the
other two privileges are enabled for me, or are grantable by me to a
process?  I am currently a member of the administrators group on the
machine that I am coding on.

thx

Mark
