-Domain Name System (DNS) plug-in
-
-Implements a set of commands useful for manipulating DNS records used by
-the BIND LDAP plug-in.
-
-EXAMPLES:
-
- Add new zone:
-   ipa dns-add example.com nameserver.example.com admin@example.com
-
- Add second nameserver for example.com:
-   ipa dns-add-rr example.com @ NS nameserver2.example.com
-
- Delete previously added nameserver from example.com:
-   ipa dns-del-rr example.com @ NS nameserver2.example.com
-
- Add new A record for www.example.com: (random IP)
-   ipa dns-add-rr example.com www A 80.142.15.2
-
- Add new PTR record for www.example.com
-   ipa dns-add-rr 15.142.80.in-addr.arpa 2 PTR www.example.com.
-
- Show zone example.com:
-   ipa dns-show example.com
-
- Find zone with "example" in it's domain name:
-   ipa dns-find example
-
- Find records for resources with "www" in their name in zone example.com:
-   ipa dns-find-rr example.com www
-
- Find A records for resource www in zone example.com
-   ipa dns-find-rr example.com --resource www --type A
-
- Show records for resource www in zone example.com
-   ipa dns-show-rr example.com www
-
- Delete zone example.com with all resource records:
-   ipa dns-delete example.com
-
- Resolve a host name to see if it exists (will add default IPA domain
- if one is not included):
-   ipa dns-resolve www.example.com
-   ipa dns-resolve www
-

-# A few notes about the LDAP schema to make this plugin more understandable:
-#  - idnsRecord object is a HOSTNAME with one or more resource records
-#  - idnsZone object is a idnsRecord object with mandatory SOA record
-#    it basically makes the assumption that ZONE == DOMAINNAME + SOA record
-#    resource records can be stored in both idnsZone and idnsRecord objects
