Quoting Daniel Müller <muel...@tropenklinik.de>:

I had a test system running with the same rpms. Did the setup as described
and could not change user passwords and sync things the
way it should to my ldap slave. In the end I recognized I had to run winbind
on the pdc!?
And after all I was missing a real step by step setup. So I returned to
smba/ldap smbldaptools setting up my system in an hour(Master - Master
Repication).
If you can post your editposix setup to me I would try a second time :-)

" ldapsam:editposix"-Is as I can tell not a good solution whenever I tried
this it did not
Work right. And there is nowhere a good and new howto about this feature.

Hello,

I can't join a winxp box to my samba domain.  I just have one samba
server, meant to act as a PDC for domain='CHI'.
Any ideas how to troubleshoot and/or remedy?

Thanks,

Jon

Context:
------------
samba v3.3.8 on CentOS v5.5, using ldapsam backend.  Domainname ='CHI'.
smbldap-tools v0.9.6.
I 'populated' the ldap with 'smbldap-populate'.

I try to join the winxp box, authenticating to the domain as user
'jdetert', which is a member of the 'Administrators' group:
# smbldap-groupshow Administrators
dn: cn=Administrators,ou=Groups,dc=infinityhealthcare,dc=com
objectClass: top,posixGroup,sambaGroupMapping
gidNumber: 544
cn: Administrators
description: Netbios Domain Members can fully administer the
computer/sambaDomainName
sambaSID: S-1-5-32-544
sambaGroupType: 5
displayName: Administrators
memberUid: jdetert,root

What happens:
----------------------
a failure dialog window pops up on the winxp box with this message:
'The following error occurred attempting to join the domain "CHI":
The user name could not be found.'

-- snip --

I am working through a similar setup at the moment.

Looking at the smbldap-useradd source, status 9 is "user must not exist
in
LDAP", so I assume from that that the workstation userid already exists?


Turns out you are correct.  So, I deleted the 'user'="testfsclient$"
from the ou=Computers, and retried, but it failed with the same error,
and it re-created the user object.

Any ideas how/why joining the domain is not fully working?

Thanks,

Jon

A couple more things:
1) smbldap-populate initializes the sambaGroupType for all the
S-1-5-32-* SIDs to 5.  This is incorrect.  It should be 4, but this
probably isn't causing this issue.
2) I think that root needs to be in the Domain Admins group in order
to join a machine to the domain, not the Administrators group which is
a local group.  At least that is how I am set up.
3) Depending on the details of your implementation you may not need to
use smbldap-tools at all.  Have a look at the ldapsam:editposix and
ldapsam:trusted on the smb.conf man page.  Note that using
ldapsam:editposix is one case where winbind is required on a Samba PDC.

Exactly how did ldapsam:editposix not "work right"?

I thought that the smb.conf man page described things well enough.

I have converted my test set up from using smbldap-tools to using
ldapsam:posixedit and so far it is doing everything that I was using
smbldap-tools for correctly.  I am using the SerNet 3.5.6 RPMs.

From a working smbldap-tools configuration all I did was comment out the "script" options in smb.conf and add ldapsam:editposix = yes.

So all the relevant options for me would be:

# LDAP Configuration
passdb backend = ldapsam:"ldap://127.0.0.1";
ldapsam:trusted = yes
ldapsam:editposix = yes
ldap ssl = off
ldap suffix = dc=example,dc=com
ldap machine suffix = ou=Computers,ou=Users
ldap user suffix = ou=People,ou=Users
ldap group suffix = ou=Groups
ldap admin dn = cn=sambaadmin,dc=example,dc=com

# Winbind/Idmap
idmap backend = ldap:ldap://127.0.0.1
ldap idmap suffix = ou=Idmap
idmap uid = 10000-20000
idmap gid = 10000-20000

I have nss_ldap setup and you must run Winbind as Idmap is used to allocate UIDs for new accounts/machines. I use LAM to do user admin so editposix is really only being used to join machines to the domain and for users to change there passwords. But with these functions I have had no issues so far.
