[Samba] Samba 3 - ntlm_auth ntlmssp failing
Is /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp supposed to be
working at this stage of samba 3? With RH EL3 beta (taroon) which comes
with samba-3.0.0-3rc1.3E packages (and squid-2.5.STABLE3-2.3E packages),
the /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic helper works
great but /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp always
fails (NTLMSSP NT_STATUS_ACCESS_DENIED). This is with an NT domain
controller. We're running samba 2.2.8a everywhere else, this is first
jump to 3.0.
Only winbindd is running, not samba. Here is the smb.conf:
[global]
workgroup = TCS_MAIN_DOM
netbios name = LINBETA
server string = Samba Server on LINBETA
interfaces = eth0 127.0.0.1/24
bind interfaces only = yes
security = DOMAIN
encrypt passwords = Yes
password server = tcs_main_pdc
username map = /etc/samba/smbusers
log level = 1
log file = /var/log/samba/%m.log
mangling method = hash2
preferred master = No
domain master = No
dns proxy = No
wins server = tcs_main_pdc
kernel oplocks = No
winbind uid = 10000-20000
winbind gid = 10000-20000
winbind use default domain = yes
winbind enum users = yes
winbind enum groups = yes
blocking locks = No
locking = No
oplocks = No
level2 oplocks = No
guest account = nobody
load printers = no
Here is a squid/ntlm_auth log of the transaction. Should I file a bug
report or is there some setting that needs to be made on the PDC?

[Samba] Samba 3 - ntlm_auth ntlmssp failing
Andrew said it wasn't well documented yet, but the winbindd_priveledged pipe needed to be readable by squid. Chgrp'ing the winbindd_priveledged directory (it was chmodded 750) to the squid group solved my problem, it's now working great. ~ Daniel ----------------------------------------------------------------------- This message is the property of Time Inc. or its affiliates.
