User-ID not mapping all traffic

[raji_toor]

Why the user-id is missing for some traffic. This also causes issue with policies using user-id. 

Below traffic log is for same user/zone/ip

this has become some serious issues in my environment. I have 20 firewalls and 10 ipsec site to site. 

the recent issue I just realized is that if a user on GP crossing ipsec tunnel from PA to PA, the user id will be dropped at the destination, 

and now all the rules will be denying because it can not see the username.

this is very unstable, since 2017, I have been opening tickets 2~3 times a year and still no solid solution.

Some critical information is missing from your explanation but I will assuming your setup is the following:

1.  UserA connects via GP to FirewallA

2. UserA then accesses a resource behind  FirewallB

3.  FirewallB  has an ipsec s2s tunnel to FirewallA and this is how GP users are reaching the resource behind FirewallB

If the above  is true, then FirewallB needs to be receiving redistributed GP mappings from FirewallA.  FirewallB doesn't magically know about the ip to user mapping of UserA that is known to FirewallA.  FirewallB must be told wha the ip to user mapping is by configuring user-id redistribution.

[Arjang999]

you are right on the setup.

and I have user identification enabled on the tunnel ZONEs, and both firewall A and B are pointed 4 AD servers for monitoring and user id mapping. 

but Im guessing I would need the redistribution ?

thanks for your reply.

Your guess is correct, you do need user identification, but you also need redistribution.  User identification turns on the ability to learn mappings and redistribution actually sends the mapping from FirewallA to FIrewallB.
