Problem activating FTP and a few thoughts on FM 7 server

My current problem...

The document Ricoh points to

http://support.apple.com/kb/HT4704?viewlocale=en_US

When trying to run the line in paragraph 1 of this document I get an error:

"dseditgroup -o create -n /Local/Default -u ladmin com.apple.access_ftp"

It asks for a password and then tells me:

"Failed to set credentials."

I suspect I'm missing a parameter or something but the document is of no help there.

I have tried searching the discussion list, but if I try the advices offered there I get messages like:

"nothing found to load"

Can anyone help?

TIA Hans
