permissions on win32 [Q]

[Mark Hammond]

NT security is a bit of a black art.  Build 124 has
win32security.SetFileSecurity().

The next question will be how to create a security descriptor - here is some
sample code.

[Oh damn - just realised that pywintypes.SECURITY_DESCRIPTOR() doesnt
actually exist in 124 - it will in 125.  sorry - you will probably get stuck
here...  But Ill still post it as reference for build 125 and later]

Mark.

def CreateSD(userName):
 sd = pywintypes.SECURITY_DESCRIPTOR()

 sidUser = win32security.LookupAccountName(None,userName)[0]
 sidCreator = pywintypes.SID()
 sidCreator.Initialize(ntsecuritycon.SECURITY_CREATOR_SID_AUTHORITY,1)
 sidCreator.SetSubAuthority(0, ntsecuritycon.SECURITY_CREATOR_OWNER_RID)

 acl = pywintypes.ACL()
 acl.AddAccessAllowedAce(win32file.FILE_ALL_ACCESS, sidUser)
 acl.AddAccessAllowedAce(win32file.FILE_ALL_ACCESS, sidCreator)

 sd.SetSecurityDescriptorDacl(1, acl, 0)
 return sd
