[Samba] smbldap-useradd.pl -a -w '%m' questions

[Larry McElderry]

This is what I have:
add machine script = /etc/samba/smbldap/smbldap-useradd -w '%u'

Which has been working for several months now.

Subject: [Samba] smbldap-useradd.pl -a -w '%m' questions


I am still trying to troubleshoot my problem of not being able to join
computers to the domain.

I have found this comment by John Terpstra:-

Two questions:-

1.  Am I right to have the following line in smb.conf?

add machine script = /var/lib/samba/sbin/smbldap-useradd.pl -a -w '%m'

Samba by Example omits the -a and has '%u'.  (Example 6.4)

2.  Samba by Example 6.3.5.10 recommends setting uid=0 for the
Administrator account:-

./smbldap-usermod.pl -u 0 Adminstrator

which contradicts John's advice above.

Could uid=0 be causing my problem?  What uid should Administrator have?

Back to the problem of not being able to join the domain ...

John says that -a and -w must be used together so that both entries are
created in one operation, however, even having done this, I see the
following in slapd.log:-

which looks like it's doing 2 ADDs for UID=GARYB-1000$ and the second one
fails with tag=105 err=68, which I have found from another source to mean
"attempt to add duplicate object".

Can anyone throw any light on what's going on here and how I should
proceed, please?  Some help would be greatly appreciated.
