问题
I've been running one Django app with Single Sign-On enabled by mod_auth_sspi using mod_wsgi.
Apache/2.2.21 (Win32) mod_wsgi/3.3 Python/2.7.2 mod_auth_sspi/1.0.4
Problem is, that I can't add second Django app, which uses the same modules, because I want to use Single Sign-On too. If I add second app, Apache authenticates only the first requested app. The second one throws Error 500 - Internal server error. If I restart Apache and try to request second app at first, it works. But then when I request the first app, it throws error 500 (same error as the first).
error.log:
mod_wsgi (pid=4724): Exception occurred processing WSGI script 'C:/www/app2/app2.wsgi'.

Do you know what to do to get both apps work with Single Sign-On? I don't know, if it is Django's fault, mod_wsgi fault or mod_auth_sspi fault. Can you help me, please?
EDIT: It looks, that it doesn't depend on mod_auth_sspi module.
回答1:
It seem to be a pywin32 error, answered here: Multiple django sites on Apache / Windows / mod_wsgi - problem with win32
There is some python version check, which does something with modules and raises:
AssertionError: assert sys.modules[modname] is old_mod
Bug is reported, but not resolved:
https://sourceforge.net/tracker/?func=detail&aid=2905909&group_id=78018&atid=551954
https://sourceforge.net/tracker/?func=detail&aid=3496224&group_id=78018&atid=551954
Temporary solution is comment out two lines in win32/lib/pywintypes.py:
if sys.version_info < (3,0):
#next two lines are problematic!!!!!
#assert sys.modules[modname] is old_mod
#assert mod is old_mod
pass
else:
assert sys.modules[modname] is not old_mod
assert sys.modules[modname] is mod
# as above - re-reset to the *old* module object then update globs.
sys.modules[modname] = old_mod
globs.update(mod.__dict__)
