(SMP Server) -

<br>
With Devil-Linux 1.2.6 our very simple (perhaps too simple) Samba setup
[see below] worked like a charm.<br>
<br>
Now using DL 1.2.10 (test) it is very slow for the first access by any
machine, and again after a while (if the Samba share has not been
accessed in a while) it is very slow again. A similar problem (though
it seemed worse) occurred with DL 1.2.9.<br>
<br>
Looking at the log files (which I never did before, they weren't even
saved previously), I find this stuff (for the log file for any machine
that has accessed the Samba share):<br>
<br>

<br>
So it seems to me that when a machine accesses a Samba share, Samba
tries repeatedly to use LDAP and fails, then after 16 tries (and 16
seconds) it gives up and provides access anyway.<br>
<br>
Either I need to get the Samba - LDAP bit working (which I guess was
not a requirement with DL 1.2.6 / Samba 3.0.14a), or find a way to

An old posting I found which makes me wonder if LDAP is integrated and
is required in the new Samba build in DL:<br>
<pre>"Samba does not require LDAP libraries, but it sounds like the nmbd binary you are using has been

I think I have solved this by adding to [global] in smb.conf:<br>
<br>
passdb backend = smbpasswd<br>
<br>
I think what has happened is that with LDAP now installed in the DL
Samba build, if you don't specify the passdb backend method, it tries
LDAP then tdb (or possibly the other way round). Eventually it goes
back to smbpasswd (I guess) but takes a very long time (16 seconds) to
do so.<br>
<br>
With this parameter my Samba server is now running at speed again.<br>
