Yes, and in my testing with a similar rule: $ ipa hbacrule-show allow_sshd Rule name: allow_sshd Enabled: TRUE Users: admin Hosts: client.ipa.test Services: sshd admin can ssh to client.ipa.test but it's not possible to su to admin. Please follow https://fedorahosted.org/sssd/wiki/Troubleshooting and check /var/log/secure and the sssd logs. Also, you're not calling su as root, are you? -- Manage your subscription for the Freeipa-users mailing list: https://www.redhat.com/mailman/listinfo/freeipa-users Go to http://freeipa.org for more info on the project
