Hi Rubens,
I must admit I'm not really knowledgeable about Kerberos, but since you say the authentication is succeeding, but you end up with a blank screen afterwards, it would be interesting to know which session type you were using (KDE, GNOME, XFCE, LXDE, ... or maybe Published Applications or a single application) - maybe your problem isn't related to Kerberos at all. Also, what happens when you switch to a different session type?
And what is the output of "klist -fv"? Is the ticket Proxyable, Forwardable, Initial?
Hello Stefan, thanks for the reply.
It's not exactly a blank screen, I took a screenshot of the error with the --debug log besides it: https://drive.google.com/open?id=1cgBI3-ARfW4IDdnJeG-4K_iSAhjXuEoz
I'm trying to log in to LXDE, and when I try XFCE, Published Apps and even Terminal I get the same problem. Also, monitoring the syslog on the X2Go server machine I see no X2Go activity during these attempts. Anywhere else I should look that could help troubleshooting this?
After I issue the initial ticket and unsuccessfully attempt an X2Go login, "klist -f" outputs:
Ticket cache: FILE:/tmp/krb5cc_1000 Default principal: remoto@KERBEROS.COM

Again, any help is appreciated.
