I did some work on the getgrent NIS routines before 2.1 went out. It
should now be much less sensitive to this kind of problem. Note that
there is an inherent limitation in the size of an NIS map entry, which
is 1024 bytes (the constraining variable is YPMAXRECORD in yp.x). The
getgrent code also limits the length of an /etc/group line to 1024 bytes.
There is also an upper limit in the maximum number of members per group,
which is 200. (I think I said 1024 in an earlier post -- my mistake: I
had NIS on the brain :).
