CherryPy not playing nicely with win32com?

[infidel]

I've been trying to get my CherryPy server to authenticate users
against our network. I've managed to cobble together a simple function
that uses our LDAP server to validate the username and password entered
by the user:

# ldap.py
from win32com.client import GetObject

ADS_SECURE_AUTH ENTICATION = 1

def login_valid(use rname, password):
ldap = GetObject("LDAP :")
try:
ldap.OpenDSObje ct(
'LDAP://XXXXXXXX.US',
'XXXXXXXX\\' + username,
password,
ADS_SECURE_AUTH ENTICATION
)
return True
except:
return False

This function works great if I call it from the interactive prompt:

import ldap
ldap.login_vali d('mylogin', 'XXXXXXXX') # pass incorrect network password False ldap.login_vali d('mylogin', 'XXXXXXXX') # pass correct network password

True

But as soon as I have my CherryPy filter call this exact same function,
I get an "invalid syntax" COM error:

Traceback (most recent call last):
File "C:\Python24\Li b\site-packages\cherry py\_cphttptools .py", line

line 88, in Moniker
moniker, i, bindCtx = pythoncom.MkPar seDisplayName(P athname)
com_error: (-2147221020, 'Invalid syntax', None, None)

I don't get it. How can it be ok at the >>> prompt but invalid under
CherryPy?

Just an idea: because in CherryPy it is running in multithreading mode?
If you are using threads together with COM stuff, you will have to
add pythoncom.CoIni tialize() and pythoncom.CoUni nitialize() calls
in your code -- for each thread.

That worked perfectly. Thanks a million!

I used to hate COM just because of our huge VB project. Now I can hate
it for this too!
