How to write user search filtering from LDAP in keycloak correctly?

Question

LDAP

Good afternoon!
I'm trying to set up user synchronization in keycloak
There was a problem, there are users on ldap that I don't need to synchronize.
They can be identified by the mask sAMAccountName=$duplicate
How can I exclude all users matching the mask in user Federation in the Custom User LDAP Filter field?

Answer 1

I didn’t try to mock AD like that because such filters are the consequences of the OU structure made through a well-known place, but maybe this will help
