Is it intentional? If yes, could you please explain why, or point me to a documentation where I can find the answer?
A backtrace and a snippet of code follow:

Thanks,
Hi,
I already replied on the 18th, but I sent the mail to Jan only by accident. I'm copying my previous reply below:
FWIW, the backtrace comes from the SSSD. Only frames #14 and up are really relevant.
Since SSSD is often used in some kind of offline mode (either completely offline or just not connected to the VPN), startup should in my opinion be non-blocking.
Could there maybe be an option to pass in the hostname during initialization instead of having openldap figure it out? I'm fine with contributing a patch, if we agree on what the direction should be.
Put the hostname in /etc/hosts, end of story.
