Greetings, I'm working on a CGI program that will run under MS IIS 5.0 and will browse folders on three other machines, building HTML pages that will provide links to these folders.
Essentially, the CGI will connect to each machine in turn, doing the FindFirst/FindNext process based on the current criteria. It will select certain files/folders, and build an HTML page as it goes. The premise is fine. If I run the program from the command line, it seems to work fine and I get my HTML code out. I can copy the code into a separate file, open it in the browser, and all appears right with the world. However, when I try to run the CGI from the browser itself, I get all kinds of problems. The first one I got was a 1312, "A specified logon session does not exist. It may have already been terminated." After doing some searching, I began to investigate impersonation of a logged on user. This produces a different error: 1314, "A required privilege is not held by the client." The code involved and the output I'm getting follows: ---------BEGIN---------- class Impersonate: def __init__(self, login, password ): self.domain = '4Q9ND21' self.login = login self.password = password self.handel = None def logon(self): tracelist.append("Impersonate logon step 0") win32security.RevertToSelf() # terminates impersonation tracelist.append("Impersonate logon step 1") self.handel = win32security.LogonUser( self.login, self.domain, self.password, win32con.LOGON32_LOGON_INTERACTIVE, win32con.LOGON32_PROVIDER_DEFAULT ) tracelist.append("Impersonate logon step 2") win32security.ImpersonateLoggedOnUser(self.handel) tracelist.append("Impersonate logon step complete") def logoff(self): win32security.RevertToSelf() # terminates impersonation if self.handel != None: self.handel.Close() # guarantee cleanup ----------END----------- and I execute this code with the following ---------BEGIN---------- impersonate = Impersonate( 'PYTHONTEST', 'PYTHONTEST' ) try: tracelist.append("about to attempt the IMPERSONATE") impersonate.logon() tracelist.append("impersonate did NOT throw exception") b=AdjustPrivilege(SE_SYSTEM_PROFILE_NAME) b=AdjustPrivilege(SE_TCB_NAME) try: tracelist.append("win32api.GetUserName = " + win32api.GetUserName() ) # print win32api.GetUserName() #show you're someone else finally: impersonate.logoff() #return to normal except: a = "Impersonate Logon Error: %s %s" % (sys.exc_type, sys.exc_value) tracelist.append(a) # print sys.exc_type, sys.exc_value ----------END----------- When I run this code, my tracelist comes out with ---------BEGIN---------- 2005-09-15 16:43:37 about to attempt the IMPERSONATE Impersonate logon step 0 Impersonate logon step 1 Impersonate Logon Error: pywintypes.error (1314, 'LogonUser', 'A required privilege is not held by the client.') ----------END----------- I'm coding this in Python 2.4 and the Windows extensions. I have a number of other CGI programs in Python running under IIS that work correctly, but those only do database accesses. This one I'm trying to put together is the first one to actually do file searches. I have set the privileges for the logged on account on my IIS box for SE_TCB_NAME, SE_CHANGE_NOTIFY_NAME and SE_ASSIGNPRIMARYTOKEN_NAME and rebooted. To no avail. I'm not sure if there are additional alterations that need to be done to the security policies or not. Again, I'm not a guru. If anyone can give me more information/guidance I would greatly appreciate it. If you need more information from me, I will do my best to provide it.
