If you read what Ted says on the link I sent, he explains that older software
expects user names in a certain format - the format that is recommended by 
adduser.

Sorry it turned out to be a red herring for you - when I was caught out by this,
the adduser man page helped me - it explained why I could do something in
adduser and not the installer - adduser follows the "may" path, the installer
follows the "recommended" path.

Also in the link I sent, was the code from the installer (4.7) - and that shows
what the installer was/is doing.

HTH.
