UserID - nt authority\accesso anonimo

Hi guys,




panOS 7.1.11 -- UserID agent 7.0.4


I got issue with UserID that is currently receiving identites from UserID Agent.

UserID has already mapped IP address with a specific LDAP user for example "\test".

Sometimes happens that UserID starting to map the same IP address with this user: "nt authority\accesso anonimo (anonymous access)".


I believe that UserID Agent takes this user from somewhere..but I checked personally:


1. UserID status -- No issues

2. AD -- I didn't find anywhere "nt authority\accesso anonimo"

3. Other users mapped with UserID agent are working properly


I think this is NOT a Palo Alto's issue.


Just per confirmation guys, do you have experienced this behavior before?



Thanks in advance,

Not sure why UserID is picking this up but you can exclude this user from Palo side.


Sometimes some software (like AV) might fool UserID with it's own user account.
