I'm in the process of following John's excellent instructions for
transfering an NT4 domain to Samba 3.0.20 running on 2.6.9-gentoo-r6 on
an Intel box.
Most things seem to work fine apart from the transfer of the machine
accounts. These do not get moved because as retrieved from the NT
server the name is in upper case and adduser refuses to add names in
upper case, so I get the message 'unable to add posix account'. I
presume that adding in lower case will work just as well but there are
rather a lot of them and I'd prefer the automated approach.
Has anyone solved this before me?
Congratulations - you have been bitten by the paranoid shadow tools.
Someone made the great decision that no *n*x account should be in upper
case.
Goes all the way back to the days of teletypwriters and occasional dumb
serial terminals that only knew uppercase.
If the login name came thru to getty all uppercase, than for the
session, uppercase was mapped to lowercase. This allowed a person to
move around logging in from hi-tech upper/lower case terminals and stupid
uppercase only terminals as the same user. IBM terminals were a big
offender back then. Hollerith to EBCDIC.
This probably ought to retire, but it's so implicit in so much legacy code.
Everything you say is right on! However, the decision to implement this severe
limitation at a late stage in the game is inexcusable in my opinion.
Why should we suddenly be bitten by a new policy that permits no uppercase
characters and no spaces in user and group names? This was a bad decision
that enforces an unnecessary constraint. I am glad it has been reverted as it
was a silly decision to do this.

I fear I'm old enough to remember upper case logins.....
So simply moding the adduser script to change uc to lc will do the job?
I'll give it a go.
