The connection is kept open until the connection object is garbage collected, if you call
the binding method without a block. However, if you call the binding method with a block,
the connection is closed using Conn#unbind at the end of the block.

Also, Ruby/LDAP wraps up the native LDAP library as Francis wrote. So behavior
of the binding and unbinding methods rely on C API called ldap_bind() and ldap_unbind()
defined in RFC1823. In particular, ldap_unbind() is defined to close the connection as follows.
   4.3.  Closing the connection
     ldap_unbind() is used to unbind from the directory and close the
     connection.
           int ldap_unbind( LDAP *ld );
