Login does not work with krb5 after upgrade to 16.04.1 from 14.04.5

[Thomas Schweikle]

After having managed to have a 1024x768 lightdm screen displayed begging to login, I've tried and being prompted with "You where logged in with cached credentials".

Not really: I am logged in, but immediately thrown out again. It is impossible to work!

It looks like sssd is not running (see "connection refused" error below):
Nov 24 19:31:08 hostname login[1686]: pam_unix(login:auth): check pass; user unknown
Nov 24 19:31:08 hostname login[1686]: pam_sss(login:auth): Request to sssd failed. Connection refused
Nov 24 19:31:08 hostname login[1686]: Libgcrypt warning: missing initialization - please fix the application
Nov 24 19:31:08 hostname login[1686]: pam_unix(login:account): could not identify user (from getpwnam(sct-muc))
Nov 24 19:31:08 hostname login[1686]: Authentication failure

I suggest you inspect the sssd logs and try to figure out why it hasn't started properly. There are other services that failed to start, like smartd, so maybe something went really wrong with the release upgrade.
