[Samba] Vampire and Capital Letters

[Simon Faulkner]

I find Linux to be a nightmare if usernames have capital letters.

Some old Windows PDCs that we are vampiring have usernames with capital 
letters.

AFAIK you can't change a windows username

Is there a way of telling the vampire to make all usernames lowercase as 
it imports them?

Can I use pdbedit or any other tool to make them lowercase?

At the moment I am changing /etc/passwd and the rest in vi then binary 
editing passdb.tdb to make them lower case - ugh!

What do other folks do?

TIA
