Hi
KDC info can be retrieved from a DNS server but how often does MIT krb5 request for it? I grabbed some packets and it seems there are 6 rounds of requests within 3 minutes. The DNS server I am querying returns answers with TTL of 10 minutes so it looks like not honored.
I tried to read the source codes but haven't spotted a cache or something similar.
Thanks
Max
