Forms authentication error 4005

A

Adrian Parker

We have an application that's running ok on most of our customers machines,
but on one of them we get an error. They're running on windows 2003 server
with iis6. In the web.config, the authentication is set to forms, and the
form tag contains: timeout="25" slidingExpiration="true"

Event Type: Information
Event Source: ASP.NET 2.0.50727.0
Event Category: Web Event
Event code: 4005
Event message: Forms authentication failed for the request. Reason: The
ticket supplied has expired. Event detail code: 50202

Any ideas ?

Is this a web farm or are you using a web garden? If so, is the machinekey
set in the web.config so it matches the others systems? If not, then it will
be using the wrong key to decrypt the authentication ticket.

Also, check to see if the application is recycling. It may be creating new
sessions and or messing up the ticket if it's recycling too often. I had one
instance similar to this where the application pool was recycling every
minute because the resources available to ASP.Net were set too low and it
was always trying to recycle to release them.

It is just a plain standard single machine website.

How do you change the resources available to a asp.net ?

All I can find is that on the app pool recycle page:
Recycle worker process (in minutes) : 1740

Does this happen after 25 minutes have elapsed ( the timeout you set ) ?
Or, does it happen before the timeout has occurred ?

Also, note that, to prevent compromised performance, and to avoid multiple browser
warnings for users who have cookie warnings turned on, the cookie should be updated
when more than half of the specified timeout has elapsed.

This might cause a loss of precision...or that feature might be non-functional.

Ah, would this be caused by the session timeout being longer than the cookie
timeout ?

Hi Adrian,

Since the web application works well on most machines, I don't think the
problem should be related to your ASP.NET application's code logic or
setting. Also, when you perform the test, are you using the same client
machine to access all those webservers that host your web application? If
so, this can ensure that it is not the client machine which may cause the
error behavior.

Also, you can try comparing the difference between the problem server and
those server that host your application well.

BTW, is the error occuring occasionaly or frequently or does it always
occur under a fixed condition? Based on my experience, there does exists
some similar issue that may occured when the application deployed in
webfarm or webgarden mode. As for the "How do you change the resources
available to a asp.net" , this is the setting of your ASP.NET worker
process, and it depend on whether the server is using IIS5 or IIS6. for
IIS5, ASP.NET worker process use the setting in the machine.config
<processModel> element to control its recycle limitation. While for IIS6,
it use application pool model, so those recycle setting is in IIS's
application pool's performance/health setting. Anyway, you can have a look
at this if the error you met does likely be caused by worker process
recycling.

Please feel free to post here if you have any further questions.
