Jeremy,

	Sorry for the late response, I am still trying to recreate the
situation as well. The details are OS: Mandriva 2005 LE fully patched;
Kernel: 2.6.8.1-12mdk; configure options:

./configure --prefix=/usr --infodir=/usr/share --mandir=/usr/share
--with-configdir=/etc/samba --with-privatedir=/etc/samba --target=i686

Filesystem: ext3

smbclient output:

//root/bonza/home/david smbclient -Udavid -Llocalhost
Password:
Domain=[BONZA] OS=[Unix] Server=[Samba 3.0.25c]
