Version-Release number of selected component (if applicable):
ipa-server-3.3.3-13.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. add ipv6 reverse zone
# ipa dnszone-add 0.6.0.1.0.0.0.0.2.5.0.0.0.2.6.2.ip6.arpa.
--admin-email=admin@example.com --name-server `hostname`.
  Zone name: 0.6.0.1.0.0.0.0.2.5.0.0.0.2.6.2.ip6.arpa.
  Authoritative nameserver: ipaqa64vmj.testrelm.com.
  Administrator e-mail address: admin.example.com.
  SOA serial: 1391202431
  SOA refresh: 3600
  SOA retry: 900
  SOA expire: 1209600
  SOA minimum: 3600
  BIND update policy: grant TESTRELM.COM krb5-subdomain
0.6.0.1.0.0.0.0.2.5.0.0.0.2.6.2.ip6.arpa. PTR;
  Active zone: TRUE
  Dynamic update: FALSE
  Allow query: any;
  Allow transfer: none;

2. make sure the record exists

# ipa dnsrecord-find --name=mytestipv6host
Zone name: testrelm.com
  Record name: mytestipv6host
  AAAA record: 2620:52:0:1060:ffff:16ff:fe98:245
----------------------------
Number of entries returned 1

# ipa dnsrecord-find
Zone name: 0.6.0.1.0.0.0.0.2.5.0.0.0.2.6.2.ip6.arpa.
  Record name: 5.4.2.0.8.9.e.f.f.f.6.1.f.f.f.f
  PTR record: mytestipv6host.testrelm.com.

  Record name: @
  NS record: ipaqa64vmj.testrelm.com.
----------------------------
Number of entries returned 2
----------------------------

Make sure the host does not exist

# ipa host-find mytestipv6host.testrelm.com
---------------
0 hosts matched
---------------
----------------------------
Number of entries returned 0

3. Try to add the host

]# ipa host-add mytestipv6host.testrelm.com
ipa: ERROR: Host does not have corresponding DNS A record

]# ipa host-add --ip-address=2620:52:0:1060:ffff:16ff:fe98:245
mytestIPv6host.testrelm.com
ipa: ERROR: IP address 2620:52:0:1060:ffff:16ff:fe98:245 is already assigned in
domain testrelm.com.

Only one host exists ..

# ipa host-find
--------------
1 host matched
--------------
  Host name: ipaqa64vmj.testrelm.com
  Principal name: host/ipaqa64vmj.testrelm.com@TESTRELM.COM

----------------------------
Number of entries returned 1


Actual results:
Can not add host

Expected results:
Host add command recognizes that the dns record exist - should behave the same
as when adding with ipv4 address already exist
