X serve woes PDC+ samba

hi, i am trying to setup a PDC with our xserve, but it is being a bit of a pain the main problem i am having atm, is [code:1:2d64913e6b] smbpasswd -a bob [/code:1:2d64913e6b] this works fine, but when i go to add the machine with [code:1:2d64913e6b] smbpasswd -a -m bob [/code:1:2d64913e6b] i get this error [code:1:2d64913e6b] User bob$ does not exist in system password file (usually /etc/passwd). Cannot add account without a valid local system user. Failed to modify password entry for user bob$ [/code:1:2d64913e6b] so i figure i can manually add the details using vipw which loads /etc/passwd but upon inspecting that file, non of the users who have accounts on the xserve are listed in this file, which i find very strange as this is where they are meant to be. I am aware this is not a linux system but it certainly behaves odly so i was wondering where are these details kept and how do i go about adding the correct details for samba ?? i can't use the GUI tools becasue i am remotley logged in from a windows terminal This is really annoying me now, please help server info: os x .3 panther running darwin kernel 7.4.0 samba version 2.2.8a thanks for your help in this matter
