Hello,

I have an Active Directory LDAP and I’ve successfully connected it to my local Keycloak server throught admin-console. I created a new connection under “User Federation”.

On my LDAP I have a group of users and I want to synchronize the LDAP with Keycloak once a new user is added to my group.

I’m trying to achieve this by adding a “Custom User LDAP Filter” and the option “Periodic Changed Users Sync”, under Sync Settings. But it’s not working.

Can anybody help? Is there a way to achieve this?
