Could you please post the full output of the following command:
ldbsearch -H /var/lib/samba/private/sam.ldb cn=ren_test*
Replacing /var/lib/samba/private/sam.ldb by the real path to sam.ldb

Good Morning Rowland,





oh well, the bad side of the Internet... well the samba stuff was implemented by a former co-worker so I've to get into everything he did.

Here’s the information you’ve requested, additionally with my config files I know changed based on the samba wiki:



smb.conf:

cat /etc/samba/smb.conf

[global]

workgroup = MYDOMAIN

realm = MYDOMAIN.local

netbios name = vmu09tcse01

server string = Samba AD Client Version %v

security = ads

password server = DC03, DC04, DC01, DC02, *

server role = standalone server

idmap uid = 10000-20000

idmap gid = 10000-20000

winbind nss info = template

winbind enum users = yes

winbind enum groups = yes

winbind cache time = 10

winbind use default domain = yes

template homedir = /home/MYDOMAIN.LOCAL/%U

template shell = /bin/bash

client use spnego = yes

client ntlmv2 auth = yes

encrypt passwords = yes

restrict anonymous = 2

domain master = no

local master = no

preferred master = no

os level = 0



# Default idmap config used for BUILTIN and local windows accounts/groups

idmap config *:backend = tdb

idmap config *:range = 2000-9999



# idmap config for domain MYDOMAIN

idmap config MYDOMAIN:backend = rid

idmap config MYDOMAIN:range = 10000-99999



nsswitch.conf:

# /etc/nsswitch.conf

#

# Example configuration of GNU Name Service Switch functionality.

# If you have the `glibc-doc-reference' and `info' packages installed, try:

# `info libc "Name Service Switch"' for information about this file.



passwd: compat winbind

group: compat winbind

shadow:         compat



hosts: files dns mdns4

networks:       files



protocols:      db files

BTW: when I do

# getent passwd | grep ren_test4



I get:

ren_test4:*:12521:10513:ren_test4:/home/DOMAIN.LOCAL/ren_test4:/bin/bash



but when I do: getent passwd ren_test4

ren_test3:*:12521:10513:ren_test3:/home/DOMAIN.LOCAL/ren_test3:/bin/bash



WTF??


Cheers,

Julian
