I have worked with every load balancer on the market, I have not seen
a single one, even in HA mode, that hasn't failed completely at one
time or another. Including netscaler, which Jason indicates they are
using. We tend to be the people that tell the LB people what features
to implement (just like large ISPs tell router vendors what they
need); specifically to Netscaler I personally have worked *very*
closely with them on their feature set. I just mention that to make
it clear that it's not a case of immature/inexperienced network
Since krb5 can work quite effectively WITHOUT a LB, it simply does not
make sense to add the extra failure point (unless you have to for
other reasons like you can't change DNS).
