Hi David, Pavel Brezina (CC-ed) would know for sure as he wrote the sudo integration, but I think the trick could be to force the rules refresh to run more often, as you noted, detecting the removed rules. I'd suggest to lower the entry_cache_sudo_timeout to make the rules expire faster which would trigger the rules refresh which, if it detected rules were removed would trigger the full refresh. Currently there's no config option that would tie login and rules refresh update. _______________________________________________ Freeipa-users mailing list Freeipafirstname.lastname@example.org https://www.redhat.com/mailman/listinfo/freeipa-users
