I can send the >group file itself if needed. The traditional workaround for the 1024 bytes limit is to have multiple lines for the same group, for example: group1:x:100:user1,user2,user3 group1:x:100:user4,user5,user6 Note that everything except the list of the users is the same on all the lines. It might work for you too. -SB ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Not 1024 bytes though (that I know of). When that happens though, it is sooner than expected, and tools (like 'id') seg fault (and core dump). I have a sample group, and it appears to be hitting the byte limit. If I add a single additional character to the group, it will break things. It appears to be a combination of multiple groups. Can someone with some experience in this area comment? I can send the group file itself if needed. This box is 6.2-PRERELEASE from about mid-September. I have also seen some issues on amd64, which I went through some debugging with Konstantin Belousov back in November (cc'ed). Make sure you have rev. 1.32.8.3 of lib/libc/gen/getgrent.c. It was very strange thing with buggy code generated by compiler. I tracked it down to exact assembler instruction missed in Mr. Anderson' instance of libc.so. After that, conversation stopped. Sorry about that Kostik, the last message was for me to try a newer libc.so.6. If I recall, I tried that too. I'm not sure what else you wanted me to try. If you have more ideas, I'm all ears.

You could try: - libc.so.6 from 6.2-RELEASE CD (I suspect it will work); - compiler from same CD (e.g., try to recompile libc on clean 6.2 RELEASE installation). pgpn3IWFeBZTq.pgp Description: PGP signature
