GUEST: cant connect to db

Zeboton: I use:
* Ubuntu 13.04.
* PostgreSQL 9.2. 
* Java version "1.7.0_25"
* * OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.13.04.2)
* * OpenJDK Server VM (build 23.7-b01, mixed mode)
* NetBeans 7.3.1 downloaded from official site.

I tried to connect to PostgreSQL server in local network using Services > Data Bases > New Connection ( name of menu items may be differ because I have Russian localization for NetBean ). I filled in a form on step Connection Settings, checked connection ( it worked fine ), selected public schema on next step and gave short name to connection on the last step. After it I clicked on button OK ( Ready ) and got this exception.

Connection was not created.
