F5 & SQL Reporting server

I would try that, yes. There has to be an SPN in Active Directory for your sitename and the user account the process runs under for the HTTP protocol for Windows Integrated Auth to do Kerberos successfully. There's a bit more information hrere:

Specifically, check the section on "Resolving Kerberos Authentication Errors" near the bottom. You'll end up running:

 

 

setspn.exe -a http/f5srs.hostname.com domain\account-srs-runs-under

 

 

Do not specify "port" in the setspn command; IE 8 hates that lots.
