Hey Manuel, Im working with Citrix on almost the exact same issue. I found setting this regkey for the Linux VDA solves my issue.
"/opt/Citrix/VDA/bin/ctxreg create -k "HKLM\Software\Citrix\VirtualDesktopAgent\Authentication\UserCredentialService" -t "REG_SZ" -v "DigestMethod" -d "SHA256" --force" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2098484 Title: Pkinit fails with invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/krb5/+bug/2098484/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
