| Doc Text: |
Cause: SSSD's dynamic DNS update feature did not filter out milticast and broadcast addresses when ipa_dyndns_iface was used
Consequence: Addresses that are not suitable for DNS appeared in IPA's DNS
Fix: Multicast and broadcast addresses are now filtered out
when performing a DNS update with ipa_dyndns_iface
Result: Only the addresses that are appropriate

Upstream ticket: https://fedorahosted.org/sssd/ticket/2087 Fixed upstream:
master: 6982b488e03b8e29e186f0c54cf5f80438cceadd
sssd-1-11: a9b2c8fb47fc334c7ba9b229cde18d168059c096
Fixed upstream -> moving to POST Steps to Reproduce: 1. In LDAP, fill a user entry with a "sudoHost" attribute with a subnet: "192.168.101.0/24" 2. On a fresh Fedora 19 machine which is in the subnet "192.168.101.0/24", and which has NetworkManager service installed, the user tries to execute the command "sudo -l" Actual results: "User xxxx is not allowed to run sudo on machine" Expected results: The user is allowed to run sudo on the machine Verified for mulitcast address only as per https://bugzilla.redhat.com/show_bug.cgi?id=909430#c18 sssd version: ============= [root@rhel66-client1 ~]# rpm -q sssd sssd-1.11.6-29.el6.x86_64 [root@rhel66-client1 ~]# snip from sssd_domain_log ======================== (Wed Sep 10 14:01:19 2014) [sssd[be[testrelm.test]]] [delayed_online_authentication_callback] (0x0200): Backend is online, starting delayed online authentication.
