sudo logs show single user as su.

[Phil Foster_2]

We have a 11.00 system that everytime
someone executes a sudo command, it
shows up in the logs as being done
by one specific user, regardless of
which account does the sudo.

A reboot has fixed this in the past, but
is very cumbersome and shouldn't have to
be done to fix this. Has this been seen before?

(also, on an unrelated note, when we upgraded our
K-class machine from 10.2 to 11, performance took
a serious nose dive. Has this been reported before?)

I can't comment on the sudo command, but with regard to the 10.20 to 11.00
upgrade, you ought to check the kernel parameters as any changes you made under
10.20 may have been lost.
