SUMMARY: Strange NIS problem on SunOS 4.1.3

Hello Again Sun Managers,
        And thank you for all the answers. It seemed that the problem
was caused by too many entries in the group file that were too long. I
cleaned up a little bit the group file, and voila!.

        Other possibilities were expressed by the answers I got, and also
the existence of a nice little program distributed apparently with the
Sys V option on SunOS, called pwck, a password file checker.

        Thanks to:

and all others that might answer after I ship this message out.

And of course there aren't two entries with the same username, right?

check your password file for a blank line, a line with
too few colons in it, or check the group file for a line that's
too long. by changing a letter, you're changing the sort
sequence, and probably changing the place in whic hthe
malformed line ends up in memory -- when it straddles a page
boundary, you get a core dump.

From: (Glenn Satchell - Uniq Professional Services)Run /usr/etc/pwck to see if there are any typos in the file, eg missing
`:' perhaps on a previous line.

Thanks again,
