I have tried using kadmin, but I get an error:
root@server /etc/httpd# kadmin -p admin@domain -q "ktadd -k /etc/httpd/krb5.keytab HTTP/service1.domain" Authenticating as principal admin@domain with password. Password for admin@domain: Password for admin@domain: kadmin: Database error! Required KADM5 principal missing while initializing kadmin interface
I have been searching online, but as usual I am having a real hard time finding anything helpful relating to kerberos.
Authentication appears to be working, though I am missing principals;
