User-ID Help

In recent weeks we've had a problem reported where one minute a site will be accessible for instance Youtube and then it won't be and then it will and it goes on, after looking in the logs when  the connection to Youtube fails is when the log show no USER-ID when it works it shows a local USER-ID. We use an AD group for access to general internet and have this configured on the corresponding rule.


I've tried troubleshooting looking at various knowledgbase articles but haven't found any reason why sometimes USER-ID's are correct and and sites can be accessed and then othertimes they can't its also not happeing for all sites accessed at the sametime it may not work for Youtube but it will work for Google.


Can anyone give me any ideas why this might be happeneing?

Can you provide more information? 

What version of PanOS?

Are you using samaccountname and userprincipalname? 


Do you have the user-id agent parsing every single sec-event-log on every DC?

Do you have "enable user-id" on for every internal zone? 

Do you use Terminal Services? If so do you have that agent in that environment as well? 

Are you using the same SPG for all rules or do you have multiple SPG's? Depending on your environment you can have one source subnet hitting a different policy /w a different SPG and URL filter if configured. 


I have seen issues where a person is using a cached authentication in Windows when not connected to work via VPN and then attempts access which fails with the same type of error.  


For testing I would use sites that are not super-trackers to see if the issue is as simple as all internal zones having user-id enabled. I would also check to see when it fails from the command line what it shows.
