Hi @Padre__
In short: Use Identity Collector. It is much more safe, an this is the preferred method.
In the October 2022 Windows update (KB5018411/ KB5018419), Microsoft made changes to read privileges that affect AD Query from an Identity Awareness Gateway to a DC. If AD Query is configured for a DC user who is not an admin (see sk93938), AD Query cannot access the DC. For customers with such a configuration, Check Point recommends to use Identity Collector as the Identity Source instead of AD Query. For more information and workaround procedures, see sk180232.
