idmap backend = nss ??

Its man page is very scarce. Is it supposed to work at all? Do you have any
experience with it?

root@fs02-sibptus:~# id zimaev uid=3237(zimaev) gid=2000(user) 
groups=2000(user),2012(budget),3134(pto),2011(ntd)

Could not get info for user zimaev
root@fs02-sibptus:~#

what gives?


what do you have in smb.conf defined for security?
(general portion of smb.conf)

[global]
workgroup = SIBPTUS
wins server = 10.14.134.1 10.14.134.4
security = domain
idmap backend = nss
idmap uid = 1000-1999999
idmap gid = 1000-1999999
template shell = /bin/bash
winbind use default domain = Yes
allow trusted domains = Yes


To me it seems, since you have security = domain, samba will try to authenticate4 always to the domain controller. Therefore: wbinfo -i zimaev will not return something valid, unless you prepend the user with the domain (wbinfo -i DOMAIN\zimaev don't forget to map the backslash with a second one DOMAIN\\zimaev) :-)

More about how that works with the security:
http://www.samba.org/samba/docs/man/manpages-3/smb.conf.5.html#SECURITY

The idmap backend = nss just tells samba, where to store the mapping informations from AD- versus *nix-Users.

that's about what I know of... :)
hope it can hint you to where you'd like to go ...
