[Samba] unable to join AD domain: Failed to parse cldap reply

[Norbert Wegener]

I have a suse 10.2 system, that runs the latest samba version, Suse 
provides for 10.2: 3.0.23d-6
After  a long time I  had to join that system to an AD domain.
Unfortunately that did not work as expected.
net ads join  -U DE7B07K0 at WW901.MYDOM.NET -d4
asks for a password, but then it fails with:
