samba - Feb 2004 - idmap uid/gid range (pam_winbind OR whatevere else problem) - no ideas ?

Hi all.
This is the second message...

Has anybody ANY ideas ? :(

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...

Thanks ALL in advance!

Please, send ANY ideas.

Sincerely yours,
Mike
