[Freeipa-users] Red Hat 5 and 6 with IPA Client v. 4

Fri Sep 18 14:45:34 UTC 2015

I think I got it working.

Solution in my case was to run following on client nodes:

yum install sssd-1.12.4-47.el6.x86_64

And on IPA server for each Forward and Reverse lookup zone I ran:

ipa dnszone-mod XXXXXXXXX.COM. --allow-sync-ptr=TRUE --dynamic-update=TRUE
ipa dnszone-mod 44.28.10.in-addr.arpa. --allow-sync-ptr=TRUE --dynamic-update=TRUE

Ultimately I think bringing all nodes to SSSD 1.12.4 version solved the problem.

Thank you, IPA team, for your support!

Regards,

Andrey Ptashnik
