Is there a way to tell what encryption type is being used for the session key? I'm assuming the "3 etypes {511 511 1}" means there are three encryption types defined (which seems right)... but then there's "etypes {rep=1 tkt=1
ses=1}"  which I interpret to say the session key is type "1" (DES?).

The "3 etypes" bit should be for the encryption types the client indicates to the KDC that it supports (or that it wants used), in the request message. (Though I don't know what 511 would be; in the MIT code, 0x1ff is ENCTYPE_UNKNOWN, but we shouldn't be transmitting that in any requests. Are you actually seeing the above with an MIT client?)


  Anyway, I know RFC 1510 has some
of the older enctype IDs:

and draft-raeburn-krb-rijndael-krb-05.txt has:

http://www.iana.org/assignments/kerberos-parameters has these now, btw, except for changing 0 from "NULL" to "reserved". (Though the references are outdated and should point to RFCs; I've just asked IANA to fix that.)
