The token supplied to the function is invalid

[jg-son]

Hi,

I'm getting this error
pywintypes.error: (-2146893048, 'InitializeSecurityContext', 'The token supplied to the function is invalid')
The server is an apache httpd with mod_auth_kerb running on Ubuntu 20.04 and with a keytab from our AD. It's on the secondary authentication it fails, when validating WWW-Authenticate.

It's strange because the same web server works with curl+sspi and also with any web browser.
I have also tried the same keytab with a Flask-GSSAPI server and then requests-negotiate-sspi succeeds.

Any advice is much appreciated
Best Regards

mod_auth_kerb is dead, dude. Move on. Use mod_gssapi, this perfectly works with this library.
