                      6: 
                      7: This document should be read by those with experience
                      8: administering RedHat Linux systems.
                      9: 
                     10: NOTE: Most people will just use the LON-CAPA-krb4
                     11: rpm (available from http://install.lon-capa.org/).
                     12: You probably only would want to look at this document
                     13: if you NEED kerberos (it is not necessary for many
1.4     ! harris41   14: institutions) AND if you are installing on a NON-REDHAT
1.3       harris41   15: operating system.
                     16: 
                     17: Software dependencies:
                     18: 
                     19: * You will likely need 'devel' rpms
                     20: 
                     21:   RedHat 7.* note:
                     22:   Need several devel rpms to compile kerberos...
                     23:     db3-devel
                     24:     db2-devel
                     25:     libtermcap-devel
1.1       harris41   26: 
1.3       harris41   27: Here are the steps:
1.1       harris41   28: 
                     29: * Get the perl kerberos module from CPAN (http://www.cpan.org/)
                     30:   The module version I got was
                     31:   Krb4-1.1
                     32: 
                     33: * Get athena-kerberos-version-4
                     34:   The tarball looks like this:
                     35:   krb4-0.10.1.tar
1.3       harris41   36:   IT IS IMPORTANT THAT THIS IS THE SWEDISH VERSION, NOT THE MIT
                     37:   VERSION.
                     38:   NOTE THAT KERBEROS VERSION 4 IS A VERY DIFFERENT THING
                     39:   THAN KERBEROS VERSION 5.  (Although newer versions of
                     40:   Kerberos version 5 claim to be backwards compatible with
                     41:   Kerberos version 4...we have not tested this yet.)
1.1       harris41   42:   
1.3       harris41   43:   On the world-wide web, an example URL to get this is
1.1       harris41   44:   http://sunsite.ualberta.ca/pub/Mirror/kth-krb/src/
                     45:   Suffice it to say the tarball will likely be maintained/retained
                     46:   for sometime in the sunsite-->metalab-->ibiblio repository system
1.3       harris41   47: 
                     48:   There are several more recent releases since Sept 1999, perhaps
                     49:   we should try to use them in the future.
1.1       harris41   50: 
                     51: * Install athena-kerberos-version-4 by
                     52:   altering configure.in to read
                     53: [root@kirk krb4-0.10.1]# diff configure.in configure.in~
                     54: 27c27
                     55: < AC_PREFIX_DEFAULT(/usr/local/krb4)
                     56: ---
                     57: > AC_PREFIX_DEFAULT(/usr/athena)
                     58:      
1.3       harris41   59:   In other words, /usr/local/krb4 is what you want on this line!!!!
1.1       harris41   60: 
1.3       harris41   61: * Generate new configure file by typing this command:
1.1       harris41   62:  
                     63:    autoconf configure.in > configure
                     64: 
1.3       harris41   65: * Then, of course:
1.1       harris41   66:    ./configure
1.3       harris41   67: * Then compile:
1.1       harris41   68:   make
1.3       harris41   69: * Then install:
1.1       harris41   70:   make install
                     71: 
1.3       harris41   72: * The perl module will now install correctly
                     73:   (otherwise it would have been severely upset
                     74:    due to kerberos being in /usr/athena as opposed to /usr/local/krb4).
1.1       harris41   75: 
1.3       harris41   76: * Perl module installation is as usual:
1.1       harris41   77:   perl Makefile.PL; make; make test; make install
                     78: 
1.3       harris41   79: * Go get a cup of coffee so you don't see all the weird warning
                     80:   messages that flash at you.
1.1       harris41   81: 
1.3       harris41   82: * It really works.
