samba - Feb 2004 - idmap uid range 10000-20000: pam_winbind does NOT work ?

Hi all!

Again, unexpected behaviour!
When I set in smb.conf
idmap uid = 10000-20000
idmap gid = 10000-20000
I CAN change and SEE domain users ang groups as I change the owner of a file on
Unix:

chown domain+user ./test.txt
chgrp domain+group ./test.txt
ls -l /tmp
-rw-r--r--   1 user group            0 Feb  4 20:25 test.txt <- I SEE DOMAIN
USER AND GROUP

BUT I'm NOT able to telnet or ftp to my Unix server!!!
Otherwise, when I set

idmap uid = 1000-2000
idmap gid = 1000-2000

I CAN telnet or FTP to my Unix server using domain accounts but if I chown or
chgrp I DO NOT see domain users an groups...

In debug.log I see:

What might be the problem ?
