 Hi

Ever since setting DNN for ad authentication im getting the below error now and then. It doesnt popup much but enough to be off concern.
Its happened when access the site
Clicking on insert image in the editor and the popup comes up with the error
And accessing a page once im already logged in

What could i do to stop this error from happening?

I'm getting the same error after upgrading to 4.3.5 with AD authentication.

It's sporadically trying to run the installation routines over again, even though web.config has a < InstallationDate > setting and the database appears to recognize that it's upgraded to 4.3.5 as well.  

I suspect that maybe something in the security area (file or DB) maybe didn't get properly upgraded, but I'm not sure where to start digging.  Another thing I have noticed is that the install error is always preceded by a httpresponse error which references UserID -1.


Here's the log dump from the error:

I'm having the same problem after setting up AD Authentication with 4.3.5.  The error seems to happen the first time I attempt to browse to the site each day. It might be more frequent than that, but refreshing the browser always fixes the problem.

Also, I'm browing to the main page, but I'm getting transfered to http://wiki.nextfinancial.com/dnn/Install/Install.aspx?mode=Install, where the error shows up.

Anyone come up with an answer on this issue while trying to upgrade from 4.3.5 to 4.4.1?  I'm getting the same problem on an internal AD Authenticated Site, when I try to add a new Portal.  Thanks.

This is the same error that happened with me when I upgrade from 4.4.0 to 4.4.1.  What worked was commenting out the authentication module in the web.config (along with the other changes like machine key etc..) copying all the neccesary files over to the DNN install location, and then navigating to the install.aspx page.  Once the upgrade is complete, then un-comment the authentication module and everything should work just fine.
