hi @Pattarachai


could you elaborate on your configuration and the time you see users being identified ?


if you have userID cache enabled for 720 minutes, a mapping should remain for 12 hours at which time it is cleared


if a user is showing up as unknown you'll need to verify if the user exists on the UIDagent, and if the ActiveDirectory has a succesfull logon event in the event log

HI @reaper


I try to use  cli  "clear user-cache ip (user issue) and found ip mapping user on AD  

you also need to clear the management plane cache

>clear user-cache-mp ip 


 this will remove all entries from the firewall, but as long as the user is still listed in the userIDagent, the firewall will simply re-fetch the info and repopulate it's cache


this article may help :

Hi @reaper


OK I got it about this thing but I don't understand  why I use this cli every time  

hi @Pattarachai


I'll need more information on what exactly you are trying to achieve as I'm uncertain at this point


Please provide more details about what you see and what should be different or you expect to happen


you should not be using that cli command every time (as it is a debug command), so what enticed you to start using it so frequently


you mentioned you have the timeout set to 720, what are your objectives? if users need to be cleared sooner, you should set the timeout lower
