we have 4 servers for redundancy in krb5.conf
kdc= server1
kdc= server2
kdc= server3
kdc= server4
master_kdc=server1
master_kdc=server2
master_kdc=server3
master_kdc=server4
admin_server=server1
admin_server=server2
admin_server=server3
admin_server=server4

servers 1 and 2 are shutdown. I am unable to get kinit <userid> until I comment their lines out and bounce sssd however. 
So the failover isn't working  as expected. 

Is there anything I need to do to make this happen?

thank you
