ZabbixAPI: problems with add hosts

[InViZz]

Hello,
have some problems with ruby library for zabbix api...
when I try create new host i see "permission" error, but user is Zabbix Administrator and had API Access. Who can help me? Maybe I doing something wrong?

output from zabcon.rb -d 6:

You do not have permission to perform that operation

Using Zabbix 1.8.10
