As I've said before, this is your fundamental issue. If we cannot, for
some reason, resolve the name ldapsrv.iwm-kmrc.de in the ldap:// handler
in ldb (which is different to the ldap handler in passdb, which uses
openldap directly) then we should, and will fail.
You need to dig into the code with either a higher debug level, or under
gdb and set breakpoints to find out why this happens. A wireshark
network trace might also be revealing.
