Our intree krb4 works well with both AFS and MIT v4 KDCs, Since krb5
has v4 backward compatiblity) it works with krb , our krb4 also
interoperates with krb5.
That means its's not worthless, far from it. It is very useful to
people in Kerberos-based environments. (which, note well, includes
most AFS installations.) Until we have a suitable (krb5) replacement
it should stay in the tree.

We only have one real client in the tree, AFAIK: telnet. The
kerberised rsh/rlogin clients were removed for reasons I didnt
understand and which sounded more religious than technical.
Tho' to be completely fair, they may have some real grounds in setuid
arguments. Even so, that should be left up to the discretion of the

As I said, we dont have kerberos-aware rsh or rlogin. Telnet works
perfectly for me, and has done for years. Are you sure you installed
the krb-aware version of all of the requisite `non-exportable'
libraries (libtelnet, libcrypt) and (on a.out) reran ldconfig?
Are you sure you have the local srvtab set up properly?

Its not worthless. Far from it. Perry is just having some temporary
difficultly distinguishing *his* security needs from the security
needs of our entire user base.

There is work being done on `integrating' krb5, yes.
I'll leave it for them to answer.
