samba - Sep 2005 - change in winbindd behavior

I have a Samba 3.0.15pre1 box running winbind to a Windows 2003 AD
Domain, see the smb.conf file below.

If I run 'wbinfo -u' it returns all the expected user and computer
accounts, in lower case.

I just compiled and installed 3.0.20 and now 'wbinfo -u' is returning
mixed-case results.

I am guessing that the mixed-case results are exactly what the AD
servers are returning to Samba, but why did 3.0.15pre1 convert all
accounts to lower-case and is this functionality something which can be
turned on/off via a smb.conf option or during compile time?

-------smb.conf (less share sections) ----------------

Thanks for the rapid response.

I had searched the archives (August and September at least) and hadn't
found this.  Perhaps I needed to look earlier or search for something
other than the case of the returned user list.

Anyway....

I applied the winbindd patch found at samba.org/samba/patches and now
the computer accounts are returned all upper case and the users are
returned all lower case, but winbind seems to now be ignoring the
'winbind use default domain = yes' option in the smb.conf file as all
returned accounts (user and computer) are prefixed with the NetBIOS
domain name...
