"Kerberos and LON-CAPA, The Way it Should Be Done"
  contributed by Scott, sharrison@users.sourceforge.net
  loncapa/doc/krb_note.txt
-------------------------------------------------------

This document should be read by those with experience
administering RedHat Linux systems.

NOTE: Most people will just use the LON-CAPA-krb4
rpm (available from http://install.lon-capa.org/).
You probably only would want to look at this document
if you NEED kerberos (it is not necessary for many
institutions)AND if you are installing on a NON-REDHAT
operating system.

Software dependencies:

* You will likely need 'devel' rpms

  RedHat 7.* note:
  Need several devel rpms to compile kerberos...
    db3-devel
    db2-devel
    libtermcap-devel

Here are the steps:

* Get the perl kerberos module from CPAN (http://www.cpan.org/)
  The module version I got was
  Krb4-1.1

* Get athena-kerberos-version-4
  The tarball looks like this:
  krb4-0.10.1.tar
  IT IS IMPORTANT THAT THIS IS THE SWEDISH VERSION, NOT THE MIT
  VERSION.
  NOTE THAT KERBEROS VERSION 4 IS A VERY DIFFERENT THING
  THAN KERBEROS VERSION 5.  (Although newer versions of
  Kerberos version 5 claim to be backwards compatible with
  Kerberos version 4...we have not tested this yet.)
  
  On the world-wide web, an example URL to get this is
  http://sunsite.ualberta.ca/pub/Mirror/kth-krb/src/
  Suffice it to say the tarball will likely be maintained/retained
  for sometime in the sunsite-->metalab-->ibiblio repository system

  There are several more recent releases since Sept 1999, perhaps
  we should try to use them in the future.

* Install athena-kerberos-version-4 by
  altering configure.in to read
[root@kirk krb4-0.10.1]# diff configure.in configure.in~
27c27
< AC_PREFIX_DEFAULT(/usr/local/krb4)
---
> AC_PREFIX_DEFAULT(/usr/athena)
     
  In other words, /usr/local/krb4 is what you want on this line!!!!

* Generate new configure file by typing this command:
 
   autoconf configure.in > configure

* Then, of course:
   ./configure
* Then compile:
  make
* Then install:
  make install

* The perl module will now install correctly
  (otherwise it would have been severely upset
   due to kerberos being in /usr/athena as opposed to /usr/local/krb4).

* Perl module installation is as usual:
  perl Makefile.PL; make; make test; make install

* Go get a cup of coffee so you don't see all the weird warning
  messages that flash at you.

* It really works.
