In 1.8.1, there is the following code in src/lib/krb5/os/dnsglue.c:
krb5int_dns_init(struct krb5int_dns_state **dsp,
char *host, int nclass, int ntype)
{
...
nextincr = 2048;
maxincr = INT_MAX;
...
One day, due to an error, the number of KDC SRV records for one of our
realms doubled from 27 to 54... and KDC lookups via DNS prompty broke. I
bumped up the nextincr value above, and it started working again.
Probably not the right fix, but just letting you know that there's a bug
here.
