[c-nsp] Kerberos on Cat4000?

[Kevin Graham]

Does anyone know if there's ryhme or reason that Cat4000's don't have
Kerberos support?

Specifically, the older CatOS sups do, but not under IOS (even under
12.2SG). The only other current IOS platform (besides the 4000
derivates) like this I could find are 2950's.

Assuming this is typical marketing fun, does anyone know the product
positioning crosshairs that cause Kerberos to get dropped from a
feature list?
