Passthru troubles

[mysha]

Hi all,

For a while i have alfresco 3.2r up and running.
For it to work like our company wants i need to have passthru authentication to work.

I have configured everything like it should be and on a number of workstations (ie8) i am able to use alfresco explorer with passthru authentication.
On a few other workstations with ie7 it also works, but on the majority it doesn't. I get the following error.

net.sf.acegisecurity.AuthenticationServiceException: Failed to open passthru auth session

I compared ie7 versions and settings, registry settings, local security settings, but it doesn't change a thing.
A http debugging program shows me that when it goes right i should get 2x 401 unauthorized warnings and then log me in.
When it goes wrong i get 1x 401 unauthorized warning and then a 500 internal server error.

Anybody has an idea on what i forgot to check?

Eventually i was succesfull in getting rid of the problem.

The last thing i changed was the file-servers.properties file and adjusted the cifs.broadcast adress (255.255.255.255 to the right one) and cifs.bindto= to the right ip adress.
