    allow net ads join accept new osServicePack parameter
    
    osServicePack paramater allows the default behaviour ( which is to use
    the samba version string as the operatingSystemServicePack attribute )
    to be overridden
    Additionally make sure if blank string is passed that it is treated
    as attribute deletion. This is necessary as values for the os attributes
    are eventually passed to ads_modlist_add if the value is "" then the
    attempt to add this attribute fails in the underlying ldap
    'ldap_modfiy_ext_s' function. In this case we need to pass NULL as the
    value to force deletion of the ldap attribute
