Well, the immediate problem is that when su(1) called initgroups(3), which
is part of the process of changing your identity, it returned an error of
EPERM. Given your previous crisis, I'd suspect you missed changing the
ownership on something somewhere, or a file mode got changed as well
somewhere.
You might try running an strace(1) on /bin/su and looking at the arguments
that are getting passed to the low-level system calls. You might find some
clues there.
Here's a directory listing of some files from my Red Hat system... compare
it to yours and see if that yields any insight. In particular, check the SUID
bit on the /bin/su file.
-rwsr-xr-x 1 root root 14k Mar 7 2000 /bin/su*
-rw-r--r-- 1 root root 553 Aug 10 14:05 /etc/group
-r-------- 1 root root 456 Aug 10 14:05 /etc/gshadow
-rw-r--r-- 1 root root 1.0k Oct 5 10:28 /etc/passwd
-r-------- 1 root root 890 Oct 13 09:11 /etc/shadow

Pitty. If you were using an RPM-based system, "rpm -Va" would likely find
the problem.
