Comment 20 for bug 1747572

@Stefan
Sorry, it was my bad :)
Tests in artful successfuly PASSED. All protocols works as expected.
The reason they were fail was trivial. According to docs "To use cifs Kerberos and DFS support, the Linux keyutils package should be installed" what was not true :o)
Can you change tag to verification-done ?\

Some output:
