Repairing permission, what's an SUID file?

[BOOMBA]

Hey there.
I'm trying to repair permissions on my Mac Pro running 10.5.1 with Disk Utility, and I get this list of things it doesn't want to fix.

Repairing permissions for “Macintosh HD”
Warning: SUID file "usr/libexec/load_hdi" has been modified and will not be repaired.
Warning: SUID file "System/Library/PrivateFrameworks/DiskManagement.framework/Versions/A/Resources/DiskManagementTool" has been modified and will not be repaired.
Warning: SUID file "System/Library/PrivateFrameworks/DesktopServicesPriv.framework/Versions/A/Resources/Locum" has been modified and will not be repaired.
Warning: SUID file "System/Library/PrivateFrameworks/Install.framework/Versions/A/Resources/runner" has been modified and will not be repaired.
Warning: SUID file "System/Library/PrivateFrameworks/Admin.framework/Versions/A/Resources/readconfig" has been modified and will not be repaired.
Warning: SUID file "System/Library/PrivateFrameworks/Admin.framework/Versions/A/Resources/writeconfig" has been modified and will not be repaired.
Warning: SUID file "usr/libexec/authopen" has been modified and will not be repaired.
Warning: SUID file "System/Library/CoreServices/Finder.app/Contents/Resources/OwnerGroupTool" has been modified and will not be repaired.
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired.

Any idea what these are and why it can't modify them? I've never had problems repairing permissions cleanly before.


thanks!

(oh, running DU off the hard drive, not the disk)

This is a known problem with Leopard, don't worry

Awesome.
thanks.
They all sounded important, and freaked me out, like someone had control of my remote log in stuff.

For the record, and SUID is:

Definition: SUID (set user ID):
The SUID permission causes a script to run as the user who is the owner of the script, rather than the user who started it. It is normally considered extremely bad practice to run a program in this way as it can pose many security problems. Later versions of the Linux kernel will even prohibit the running of shell scripts that have this attribute set.

Then how do I get rid of the SUID file?
