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.
