Comment 5 for bug 1905000

On 19.10 the bug does not occur and keytab entries are correct:

I joined to AD with:
realm join --user-principal=KUBUNTU-TEST$ --automatic-id-mapping=no --membership-software=samba --client-software=winbind --computer-name=kubuntu-test --os-name=Ubuntu --os-version=19.10 MPI-DORTMUND.MPG.DE

root@kubuntu-test:# klist -kte
Keytab name: FILE:/etc/krb5.keytab

So the regression starts with 20.04.
