Here is the result:
[root at dc1 sssd]# kdestroy
[root at dc1 sssd]# kinit -k -t /etc/krb5.sssd.keytab dc1$TEEMU.LOCAL
kinit: Keytab contains no suitable keys for dc1.LOCAL at TEEMU.LOCAL while
getting initial credentials
So I guess the host doesn’t have access. How would I go about adding
access rights? Can you point me to a good document source for these
matters?
And thank you!
