Hi All, What causes this error in /var/log/messages when on XP-Pro client boots up? winbindd[4041]: idmap uid range missing or invalid winbindd[4041]: idmap will be unable to map foreign SIDs winbindd[4041]: [2009/04/02 19:38:22, 0] nsswitch/idmap.c:idmap_alloc_init(820) rn1 winbindd[4041]: ERROR: Initialization failed for alloc backend, deferred! Many thanks, -T

Are you the one that told me to go read http://us3.samba.org/samba/docs/man/Samba-HOWTO-Collection/samba-pdc.html? Anyway, in smb.conf idmap uid idmap gid From "man smb.conf" Default: idmap gid Default: idmap uid confuses me. I thought that leaving them to the default meant everyone. Am I incorrect? testparm -s | grep -i idmap Load smb config files from /etc/samba/smb.conf Processing section "[OurStuff]" Processing section "[CDs]" Processing section "[mnt]" Processing section "[netlogon]" Processing section "[printers]" Loaded services file OK. Server role: ROLE_DOMAIN_PDC No "idmap". So, the defaults, I presume? Also, if it helps, in /var/log/messages Todd over on XP-Pro appeared as nss_wins[8213]: vb-winxp (192.168.255.197) connect to service OurStuff initially as user todd (uid=500, gid=100) (pid 8213) This is where I get confused. 1) todd's #cat /etc/passwd | grep -i todd todd:x:500:100:Todd Chester:/home/todd:/bin/bash # cat /etc/group | grep -i user users:x:100: Am I correct that the 500:100 I see in passwd and group are the same todd (uid=500, pid=100) I see in "messages"? 2) does the "500" have anything to do with XP-Pro's 500 administrator's account? (Todd has an administrators account over on the XP-Pro virtual machine.) 3) Where does winbindd get its uid/pid pairs? Do I need to populate anything? Do I need to create a database for it to read? How did winbindd know that "idmap uid range missing or invalid"? What did it compare it against? Sorry for all the confusion: my mind is not all here. Many thanks, -T
