> Add (optional) {{master_kdcs}} to {{kerberos-env}} and generated krb5.conf 
> file. If {{kerberos-env/master_kdcs}} is not empty, it should contain a list 
> of IP addresses or FQDNs for one or more KDCs. Multiple entries should be 
> comma-delimited.
> According to 
> https://web.mit.edu/kerberos/krb5-1.12/doc/admin/conf_files/krb5_conf.html:
> {quote} 
> master_kdc
> Identifies the master KDC(s). Currently, this tag is used in only one case: 
> If an attempt to get credentials fails because of an invalid password, the 
> client software will attempt to contact the master KDC, in case the user’s 
> password has just been changed, and the updated database has not been 
> propagated to the slave servers yet.
> {quote}
> This should help with scenarios where multiple KDCs are in a master/slave (or 
> replicated) configuration.
