[Samba] Can't chown a file to an ADS username

Thanks for pointing that out. The trace shows that it's trying to
lstat64 /tmp/.winbindd/pipe, and not finding it.
ldd shows that it's only looking for libc.so.6, and finding it at
/lib/tls/libc.so.6
I built this from source. I've poached the smb.conf from the existing
one in /etc/samba and made the same modifcations I've had to make under
Solaris.
Here's the rest of the trace starting directly after the close(4):
munmap(0xb7dab000, 53951) = 0
getpid() = 3132
lstat64("/tmp/.winbindd", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat64("/tmp/.winbindd/pipe", 0xbff36ab8) = -1 ENOENT (No such file or
directory)
munmap(0xb7dba000, 1791) = 0
close(3) = 0
lstat64("/tmp/.winbindd", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat64("/tmp/.winbindd/pipe", 0xbff36b38) = -1 ENOENT (No such file or
directory)
munmap(0xb7db9000, 4096) = 0
exit_group(0) = ?
Any idea what I need to do to resolve the issue with the pipe not being
there?
~Eric

well , at least we know that getent calls winbind ...
"close(4)" - the last line in strace output ?
try # ldd /lib/libnss_winbind.so.2
it'll show you what libraries libnss_winbind requires , check that all
of them are exist ..
are you using RPM installation or compiled SAMBA from sources?
