Failed to located authority for name

Hi Guys,

 

Our pass-through authentication suddenly stopped working. We now receive a login prompt from Internet Explorer itself asking for our login details on the ServiceDesk server.

 

We can bypass this by pressing cancel, which takes us to the ServiceDesk login page.

 

Looking at the jespa logs, I can see this:

 

2014-06-02 08:39:28: HttpSecurityService: Failed to locate authority for name: <domaincontroller>.<domain>.com

 

Service desk can successfully add the computer account, and search all domains, so im not sure what caused this problem to start or where to start looking to resolve. No changes have been made to the service desk server at all.

 

Is there anything else I can check?

 

I also noticed the jespa.log file is quite large, at 800MB. Is there any way this can be trimmed automatically?

 

Thanks guys!
