Dear wise ones,
I have been using /etc/netgroups and NIS for some time to control access
to our machines and it has been working very smoothly. But a couple of
days ago one of the groups grew a little and it all went pear-shaped.
My experiments suggest that makedbm has an undocumented
restriction of about 1024 characters per line. (makedbm is one of the
commands that gets executed when you do cd /var/yp;make). I tried putting
continuation markers (backslash) in /etc/netgroup, but it didn't seem to
help.
The message I get from makedbm is:
problem storing third-year-ugrads (-,adriant,) ....
There are comments in /var/yp/Makefile which suggest I can solve the
problem by setting METHOD=b in it. This does indeed stop makedbm
complaining, but the other commands in the Makefile no longer work. I get
the following messages:
platon# make -f Makefile.btree netgroup
updated netgroup

pushed netgroup
Does anyone have any ideas?
