Re: Policy not working on connected Zentyal LDAP server
wait a sec, that Zentyal is somehow emulating/doing DC job ?
If that is your domain controller, not a Microsoft Server, then I guess it also do not generate correct/expected logon events and so we have nothing to work with in FSSO.
FSSO with polling or in DCAgent mode is built to work with Microsoft Servers and list of compatible ones is part of FortiOS Release Notes compatibility/interoperability section. Anything else might work but is not tested, not guaranteed and not supported solution.
