- I'm not "requiring" it, Kerberos is. How many Kerberos realms you are
- known to? I'm known to only 2 (possibly 3). Cross realm authentication
- doesn't work yet. I may indeed look at lots of docs at lots of sites
- around the net, but I am not known to most of the Kerberi in the world,
- and I am certainly not in any way privileged elsewhere in the world.
- The reason I (and I suspect most people in the world) want
- authenticated WWW is so that privileged folk at a site can read
- confidential docs and lock the rest of the world out. When proper
- cross-realm authentication is in widespread use, no-one will have to
- enter passwords to get a foreign ticket anyway.
-
- As to job control, line mode browsers start telnet happily enough, so
- they can run kinit the same way.

- But it's NOT a different protocol!! AFS Kerberos is the same procotol
- as MIT Kerberos. The only difference is in clients which translate
- passwords to keys - kinit, kpasswd and login. It just confuses matters
- to treat them differently. The easiest solution is a Kerberos client
- which understands both, which is invisible to HTTP.

-
- Neither can I. However, I'm trying to be realistic; after 3 years of
- looking after a Kerberos authenticated system, I think I know it fairly
- well. I don't think you can get round this problem. Any "roll your own"
- solution is useless unless everyone ELSE has it!
-
- I'd guess that browser writers don't want to put Kerberos functionality
- into their software - far easier to just run kinit/klog or the local
- X11 ticket manager/password changer. Tyro users see the interface that
- they're used to, rather than a line mode "dialog box".
-
- Kerberos functionality in plexus is great, but won't be used unless
- there are Kerberos aware browsers, so let's not make life difficult for
- browser writers by insisting they re-invent wheels. I'd prefer them to
- devote their talents to making the Web look nicer.
