Alexander, Thank you for your feedback!
In my environment I noticed that client machines that are on Red Hat 6 have version 3.0.0 of IPA client installed. [root@ptr-test-6 ~]# yum list installed | grep ipa ipa-client.x86_64 3.0.0-47.el6 ipa-python.x86_64 3.0.0-47.el6 [root@ptr-test-6 ~]# yum list installed | grep sssd python-sssdconfig.noarch 1.12.4-47.el6 sssd.x86_64 1.12.4-47.el6 sssd-ad.x86_64 1.12.4-47.el6 sssd-client.x86_64 1.12.4-47.el6 sssd-common.x86_64 1.12.4-47.el6 sssd-common-pac.x86_64 1.12.4-47.el6 sssd-ipa.x86_64 1.12.4-47.el6 sssd-krb5.x86_64 1.12.4-47.el6 sssd-krb5-common.x86_64 1.12.4-47.el6 sssd-ldap.x86_64 1.12.4-47.el6 sssd-proxy.x86_64 1.12.4-47.el6 [root@ptr-test-6 ~]# And I noticed particular behavior with IPA client 3.0.0 and IPA server 4.1 - when I add machines to the domain using command below: # ipa-client-install --enable-dns-updates --ssh-trust-dns —mkhomedir DNS record populate in Forward lookup zone, but no PTR records appear in Reverse lookup zones. That behavior is not the same with IPA client 4.1 and IPA server 4.1 version combination. Also during IPA client v. 3.0.0 configuration on version 6 of Red Hat I see output below: Synchronizing time with KDC... Enrolled in IPA realm XXXXXXXXX.COM Attempting to get host TGT... Created /etc/ipa/default.conf New SSSD config will be created Configured sudoers in /etc/nsswitch.conf Configured /etc/sssd/sssd.conf Configured /etc/krb5.conf for IPA realm XXXXXXXXX.COM trying https://ipa-idm.XXXXXXXXX.COM/ipa/xml Forwarding 'env' to server u'https://ipa-idm.XXXXXXXXX.COM/ipa/xml' Failed to update DNS records.
