  Misinformation being passed around by the misinformed.  NIS is concerned
with key-data pairs, the lengths of those pairs is imposed only by the
underlying database (and a couple of other things).

  Even the SunOS 4.1 implementation of NIS has no problems with
longer-usernames, its just that login truncates all user-ids to 8
characters before doing lookups (I guess, it is hard to verify without
looking at the code).  I did some real brief testing on this.

  Solaris 2.x has 16 character username support, and it definitely works
with NIS.
