  Of course, I don't want to hijack the OP's thread but as our problems
  seem to be rather similar I can also provide the corresponding slapd log:

 This looks like a simple configuration error; you have slapd configured to
 require client certificates and the client didn't send one. Either you need
 to configure the client with a certificate, or you need to relax the
 requirement on the server.
 [...]

In fact, this was also our first assumption after having analyzed the output 
for the very first time but due to our configuration this should't happen:

[...]
TLSCertificateFile  /etc/ssl-certs/ldap.crt
TLSCertificateKeyFile   /etc/ssl-certs/ldap.key
TLSCACertificateFile/etc/ssl-certs/ca.crt
TLSVerifyClient never
[...]

Moreover, this wouldn't explain why it /does/ work for some time (as far as 
our case is concerned it works as long as slapd isn't restarted). Once the 
problem has occured the server has to be rebooted in order to ensure a 
working setup again :-(

 The fact that a reboot is required indicates that any problem is not in any
 user-level code. Maybe your /dev/random has run out of entropy, or some
 other underlying system resource is gone. Maybe strace would help here.

Thanks for pointing me into the right direction. I can remember having 
problems with Apache and mod_ssl in the past as they lacked of entropy with 
no keyboard and mouse being attached to the machine. I have just installed 
rng-tools and hope that this might solve the issues.

I'll report on it as soon as I can confirm that this was the cause.

Cheers,
Fabian

You probably have to adjust the permissions on the files - Apache doesn't want 
to present them ;-)

 Try something like:

   self.scaleDraw = Qwt.QwtScaleDraw()
         # scaleDraw initialization code here

     def draw(self, painter, xMap, yMap, rect):
         # Look at the ImagePlotDemo how to use the map
   # and how you might try to draw the scales:
         # 1. figure out the scale position in pixels
   # 2. figure out the scale length in pixels
         # 3. draw the scale (see QwtAbstractScaleDraw.draw())

 Could you post your solution? I would like to transform it in an
 example.

Oh, I will try what I can do. Unfortunately, I am not that familiar with PyQwt 
yet except from doing the usual things...

Thanks,

 TikZ only reads the first two columns. The third column indicates if
 the value is in range (i) or out of range (o). To get a correct plot,
 TikZ should avoid plotting values with the o flag set, and insert a
 moveto operation when an i flag is encountered. This is definitely a
 valid feature request. I don't know how hard it is to implement this
 behavior though.

That's the exact problem, you are right. I now filed a feature request [1] and 
hope that a solution is found in the near future. Unfortunately, I can not 
contribute some work on my own as I am not familiar with latex and pgf 
internals but a mere user.

Thanks for your help,
Fabian
