I'm not saying NIS is catastrophically bad for an internal system that you
consider to be 'safe', it just comes from a time when security wasn't high up
the list of worries.  Other than it being easy as cake to setup in the first
place, I think it's hard to list *any* honest advantages over LDAP.  Sorry, I
don't consider performance to be a credible advantage, especially after
nscd/sssd have had their way with caching results.

A good LDAP setup with nested groups, and GSSAPI just beats NIS over the head
with a stick in terms of security, and once you've got a good LDAP
infrastructure you start to discover just how many tools offer some form of
LDAP integration.  Extending the schema to suit internal uses is also easy,
and querying it from within your own apps/scripts is far from difficult.
