Hello
I need to use to use ntlm_auth for samba users existing on the same
machine.(samba PDC, Squid and Openldap in the same server)

I read some mail in this list, particularly messages of Hesham S. Ahmed of Oct
7 2002 and I understand to do this I need join the PDC to itself but when I
use   net join I receive this message
# /usr/bin/net join
Unable to find a suitable server
Unable to find a suitable server

If I use
# /usr/bin/net join -S BACKUP
Password:
Could not connect to server BACKUP
Connection failed: NT_STATUS_CANT_ACCESS_DOMAIN_INFO

I use samba with ldap database, this is a piece of the smb.conf file

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
