I’m Setup Openldapv2.x,

Given the long history of 2.x from 2.0.0 to 2.4.x you should always mention the exact version you're working with.

I’m setup following guide: http://www.linuxmail.info/openldap-setup-howto/

Why don't you follow the official OpenLDAP Admin Guide?

http://www.openldap.org/doc/admin/

I’m connect from Jexplore to Openldap à OK, I can open no-ip..vv, but I open org à error appear:

Please don't send screenshots. Rather you should send the error message as text. Also everyone here prefers here if you use ldapsearch (or one of the other OpenLDAP's command-line tools) to demonstrate your problem and copy the output to a text e-mail.

Actually in your particular case the entry dc=org is not present in your directory.

Without knowing your slapd.conf (parameter suffix) I can't tell exactly whether that's simply a JXplorer usage issue.
