[Samba] Winbind / Samba auth problem after username change
BTW I noticed that most configs use the wildcard parameter. So the smb.conf now uses: idmap config * : backend = rid idmap config * : range = 16777216-33554431 But still no change... I really wonder where this old username is coming from...> -----Ursprüngliche Nachricht----- > Von: Julian Zielke > Gesendet: Dienstag, 6.

[Samba] Winbind / Samba auth problem after username change
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
services: db files
ethers: db files
rpc: db files
group: compat winbind
Sanitized version of user object:

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
