Mac OS X Server 1.x: Can‘t Change File Name Case on Mac OS Extendend Format Volume

I am trying to change the name of a file so that the capitalization is different. However, when I try to change "document" to "Document", the Workspace Manager gives me the error "Name already in use: document."
Note: This article pertains to Mac OS X Server versions 1.x, which were released prior to May 2001. This is not an issue in Mac OS X Server 10.0.3 and later.

This issue affects files and folders on Mac OS Extended format volumes (HFS Plus). It does not affect UFS format volumes.

To work around this issue, give the file an intermediate name.

For example, to change a filename 'foo' to 'Foo' do the following:

foo -> bar -> Foo
