krb5-1.11.3-35.el7

How reproducible:
always

Steps to Reproduce:
# kadmin.local -q "ank -requires_preauth -pw foo alice"
Authenticating as principal root/admin with password.
WARNING: no policy specified for alice; defaulting to no policy

Expected result, like with krb5-1.11.3-34.el7:

# ./kinittwice alice foo
Lifetime: 60s.
Lifetime: 60s.
# klist
