Rouge, or rogue? ;-)

Some LDAP servers treat an unbind as a request to close the socket, but
others do not. I suspect you need to close the socket in the client, and
you would do that by setting $ldap to undef; or letting $ldap go out of
scope so that the destructor gets called, as it is the destructor that
closes the socket. (If memory serves.)
