There's no question NIS has poor security, as bad a using a local password plus shadow file anyway. People that use it must know that. The valid use is company internal only, on systems whose data is freely available to company personnel and where accounts and groups info. isn't security critical. It's been that way for many, many years ... it's no secret. It's a pity NIS+ was such a pain to setup and use ... a bridge to far IMHO ...
