Awesome, works for me!!

```[2] pry(#<Proxy::Realm::FreeIPA>)> @ipa.call("host_disable", ["proxytest.bitbin.de"])
=> {"result"=>true,
 "value"=>"proxytest.bitbin.de",
 "summary"=>"Disabled host \"proxytest.bitbin.de\""}```

@domcleal What do you think of a bash script to create the user?  We don't have to officially distribute it, but could be in the wiki or something. 

I think it could also be fancy with an LDIF since all of this is stored in 389 AFAIK, but maybe not a good idea to interact with such a low layer of IPA...
