username resolve

[Niko Hartung]

im running a samba 2.07 as PDC. i can login with NT and Win98 users.
it works all fine.
when i set the security-rights on a file on a NT maschine i get all the
users form smbpasswd.
this also works fine, but now when i go back and want to check again, the
username disappeart, and "\\DOMAIN\user unkonown" appeart.

i think tis are both the same funktions, but what can i do that the username
are alway resolved.

thx
