I want to setup my Kerberos authentication using DNS lookups to define its servers. This can be done with URI records in the DNS database. There is given an example for KDC Discovery that looks like:
_kerberos.EXAMPLE.COM URI 10 1 krb5srv:m:tcp:kdc1.example.com
Now I try to add this record to the DNS database with
~$ sudo nsupdate > update add _kerberos.EXAMPLE.COM URI 10 1 krb5srv:m:tcp:kdc1.example.com ttl 'URI': not a valid number >
Doesn't work this way. What is the command to add the URI record? Is there another way to add the record to the DNS database?
