The last snapshot I tried before 2.2.17 was 13. When I installed 2.2.17 and 2.2.18pre9, initgroups fails sometimes. nssswitch.conf had the line: group: db files As a result, initgroups read the list from BOTH the db and from /etc/group, doubling the number of groups. For some users that exceeded the maximum, and the syscall failed with EINVAL. This may be the wrong syntax for nsswitch.conf. I haven't looked yet. It is new behavior, though. I haven't recompiled glibc. Its too big a pain. I just took "files" out of the lines for files that have DBs for them so both don't get read. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
