2.1.11: odd behaviour of secondary user groups

it appears that in Linux 2.1.11 I can no longer do operations
(read, execute) that rely on my membership in some secondary user
group, though the command id shows that I am in all that secondary
user groups. Example:

~ $ l /usr/sbin/pppwatch
-rwxr-x--- 1 root ppp 3450 Sep 25 18:31 /usr/sbin/pppwatch
~ $ id
uid=10(sz) gid=100(staff) groups=100(staff),9(floppy),11(phone),90(ppp),91(faxgroup)
~ $ cat /usr/sbin/pppwatch
cat: /usr/sbin/pppwatch: Permission denied
