icacls

I am confused by the output of icacls on Windows 2003. Everything appears to work on Windows 2008. I am trying to change permissions on a directory:

icacls . /grant mydomain\someuser:(OI)(CI)(F)

This results in the following error:

.: Acl length is incorrect.
.: An internal error occurred.
Successfully processed 0 files; Failed processing 1 files

The same command used on a file named "file" works:

icacls file /grant mydomain\someuser:(OI)(CI)(F)

Result is:

processed file: file
Successfully processed 1 files; Failed processing 0 files

What's going on?
