User-ID - one user occasionally not hitting the user based policy

L3 Networker

PAN-OS 8.1.2, User-ID configured with Windows AD single domain. There are security rules built, based on users/user groups. It is mostly working as intended, but specifically there's [at least] one user that has a different behavior - some user-based (not group) rules are occasionally missing, even through they did hit the policy a few moments ago. Same traffic, same packet fields - IPs/ports, etc., but suddenly it goes through Deny, instead of hitting the Permit policy. At the same time same rules works fine for a different user. After a moment, it may start hitting the proper rule again.

When checking via CLI, faulty user is registered properly- there is user-ip mapping, user-group mapping, etc. 

If creating additional rule, based on IP only, without username used - it hits that rule if it is missing the user-based rule, so there should an issue with User-ID, but not widely seen as there are a bunch of user/group rules used and they are working fine. Issue have been noticed with one specific user, but it is no different than any other user seen around.

useridd.log shows such an message, where <domain> - proper domain and <username> - username for the tricky user:

Warning:  pan_user_group_user_prime_uid_lookup(pan_user_group_multi_attr.c:1306): For <domain>\<username> user, domain <domain> does not exist in group-mapping


I've tried resetting, clearing, refreshing, etc., but that didn't help.


Don't want to overwhelm with configuration, but maybe spew some ideas where to look?




quick question,


when you created the rule for "IP" below the "user group" one, did you create a new rule from scratch.


it may be best to clone the user rule and just edit the source ip and user fields.


Also, (clutching at straws here). I would create a couple of cloned rules before the IP one to eliminate group membership issues...


1. source user = domain\username

2. source user = username


this may show some interesting results..


Or.. it may not... 


just to see if the user matches to one of these...

Cloned the rule, yep. Left everything the same, but removed source user statement.

Will try poking around, yep.

I'm also facing issue like this.

User id not fetching  in traffic logs. we created user base rule on that basis mapped ip address shows user id for same rule .but some time user is not authenticated from that user base policy rule and it is moving from next any any rule. if it is moving from any any rule that time it is not showing user-id mapping.

Has anyone found a solution to this issue?


What issue are you actually running into, can you describe your particular problem? Usually when users report an issue like this what you're running into is the user-id mapping aging out because you aren't seeing any authentication events in a timely manner so your user based entries won't match traffic anymore.
