I found the reason for this strange Samba behaviour:
The line "admin users = " in the smb.conf file was missing. I don't
know how but that was the reason.
A bit embarrassing but at least I'm breathing now.

But I am able to log on to the server when accessing shares and

And on the Mac OS X 10.4.7 (Samba 3.0.10) server I get the

I've been googling (oops, I'm not sure I can say that :-)) and
reading all the documentation I could find, but without any luck.
What's strange is that when the server was installed I was able to
add a lot of clients. Then I've probably done something wrong and
now I'm getting into trouble. So, what have I been doing?
Editing /etc/smb.conf
* Adding the line: logon home = \\[FILESERVER]\%U
* Removing the line: #logon path = \\%N\profiles\%u
Adding a group mapping with the command net
net groupmap add ntgroup="Domain Admins" unixgroup="admin"
type=domain
net groupmap cleanup
but also reverted back to default group mappings.
Reconfigured the Windows service by removing /var/samba and /etc/
smb.conf. Didn't help.
Editing /etc/openldap/slapd.conf:
* Adding a schema from ldapuserdata ( a Squirrelmail plug-in) but
has removed this schema now.
Are there other services/configuration files I have to look at?
Do you have ANY tips? This is starting to get urgent for me now!
I've now tried a couple of other things without success:
I run this command to try to add the server which is the PDC to the
domain:
net rpc join -S [SERVER] -Uroot%[password]
Today that command gave me the following output:
[2006/08/23 09:23:07, 0] /SourceCache/samba/samba-92.9/samba/source/
utils/net_rpc_join.c:net_rpc_join_newstyle(279)
error setting trust account password: NT_STATUS_ACCESS_DENIED
Unable to join domain [DOMAIN].
Yesterday I got a bit more interesting error message including
decode_pw_buffer: incorrect password length (945999123).
After searching the web I found two references regarding mac is x
server and samba about this:
At AFP548:
http://www.afp548.com/forum/viewtopic.php?showtopic=11873
There were a couple of suggestions:
1. Change the server from PDC to Single Server and back again. In a
way I've tried that by removing the /etc/smb.conf and /var/samba.
2. Set the password of the directory administrator a couple of
times and then it should work. Tried that but it didn't work for me.
At this mailing list in August 2005:
3. A tip from Michael Bartosh: /usr/bin/opendirectorypdbconfig -c
set_authenticator -r admin-name -p xxxxx -n /LDAPv3/127.0.0.1
Tried it, but didn't work.
At the moment I believe it may be the file
/var/db/samba/secrets.tdb
since I didn't delete it when I reconfigured Samba. I was also
surprised that the SID of the Samba domain didn't change when I
reconfigured Samba.
My question is then: Is it safe to rename this file and and then
start Samba again? Or will the domain loose it SID and I have to
add all the Win clients again? But if I run the command:
sudo net getlocalsid [DOMAIN]
before the renaming and then run the command:
net setlocalsid SID
after. Will this procedure do it?
