“Failed to start session” on login
I have a machine (let's name it my-machine), which runs Ubuntu 16.04.
my-machine is connected to LDAP, and I use an LDAP account to login to it. With my LDAP account, I use exclusively this machine.
However, today, I used my LDAP account to connect to another machine (let's call it second-machine), which runs Kubuntu.
After that, I am not able to login to my-machine anymore. The graphical user prompt prints error message Failed to start session.
However, when I switch to console, using ctrl + alt + F1, I still am able to login successfully.
Now, when listening to file /var/log/lightdm/lightdm.log in console, during a graphical login, here are the logs I see:
DEBUG: Authenticate result for user myuser: Success
DEBUG: User myuser authorized
DEBUG: Greeter requests default session
DEBUG: Seat seat0: Failed to find session configuration default
DEBUG: Seat seat0: Can't find session 'default'
Question
Why am I not anymore able to GUI-login on my Ubuntu machine?
How can I fix the problem?

Answering my own question
It turns out logging into the Kubuntu machine added/modified a ~/.dmrc file in my LDAP home folder, with the following content:
[Desktop]
Session=default
This is where the Can't find session 'default' log line comes from. Indeed, when taking a look at /usr/share/xsessions (as hinted in this post), the only file I find is
/usr/share/xsessions/ubuntu.desktop
Session default does not seem to exist.
Modifying ~/.dmrc to Session=ubuntu fixed the GUI-login.
