samba - Jul 2004 - Winbind and case sensitivity (revisited)

Hi

I've had a look through the archives and found this discussion on
winbind and case sensitivity:
http://lists.samba.org/archive/samba/2004-February/080321.html

The issue is that winbind will in some cases return a username
capitalized as per the NT database (ie when the user is looked up by
uid), and in other cases as per the way the user typed it (ie when the
user is looked up by username). This has cause problems for me in
integrating a Unix system into a Windows environment.

Has anyone done any work on making a patch like the one Andrew
Bartlett proposed?

If nothing has been done yet, I'd be happy to have a go. The new
option to smb.conf would be:
winbind force case = lower/upper

How does that sound?

Andrew and I spoke about this briefly on IRC last week
while debugging a different winbindd bug.  It would be
a pretty trivial change but one that would have a
large impact on existing sites I think.

So the question is how many installations will break if
winbindd all of a sudden starts lower casing usernames?

If I can be adequate feedback on this, we'll consider
making the change.

convmv can upper/lower already. it can upper lower virtually every charset
becuase it first converts everything to utf-8, then does the case conversion
and then converts back to the original encoding. When the encoding is not ASCII
it has to be specified of course. Anyway - mass-case-changing is possible ;-)

convmv -r --lower -f utf8 /path

for example.
