How to configure LDAP in java to connect using strong binds without SSL.

I need to connect to an active directory defined using strong binds (and without SSL).
I get the following exception:

Exception while checking configuration
javax.naming.AuthenticationNotSupportedException: [LDAP: error code 8 - 00002028: LdapErr: DSID-0C09018A, comment: The server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection, data 0, vece

What else is needed to perform such operation?
