Authen::Krb5::Admin is an object-oriented interface to the Kerberos 5 admin server. Currently only MIT KDCs are supported, but the author envisions seamless integration with other KDCs. PREREQUISITES Authen::Krb5::Admin requires Perl 5.005 or greater and Jeff Horwitz's Authen::Krb5 module from CPAN. INSTALLATION To install Authen::Krb5::Admin without testing, run the standard sequence: perl Makefile.PL make make install The first step will prompt you for a principal with administrative privileges on the KDC for running the test suite. Re-run this step to change which principal to use. The build script will attempt to use the krb5-config tool to discover the location of your Kerberos installation. This tool is part of the krb5-devel package on Redhat and Fedora systems and is in the libkrb5-dev package on Debian and Ubuntu systems. If it is not located in /usr/local/bin/krb5-config or /usr/bin/krb5-config you can specify the location using the KRB5_CONFTOOL environment variable. If you have a non-standard installation you can override the following locations by setting environment variables before running the Makefile.PL script. The PREFIX path is found by using the krb5-config tool. * KRB5_BINDIR - PREFIX/bin - Kerberos binaries * KRB5_LIBDIR - PREFIX/lib - Kerberos libraries * KRB5_INCDIR - PREFIX/include - Kerberos headers Currently the install scripts do NOT correctly build for x86_64 systems where the libraries are installed in /usr/lib64 (e.g. Redhat and Fedora). The workaround is to set the KRB5_LIBDIR environment variable before running the Makefile.PL script, e.g. export KRB5_LIBDIR=/usr/lib64 This will be corrected in a subsequent release. TESTING To run the test suite as part of the install, use perl Makefile.PL make test make install This step requires administrative access to the KDC by the principal specified in the first step. It will create a principal, by default "perl_test", which should NOT already exist on the KDC. If you already have a principal called perl_test, change Makefile.PL to use a different test principal, and start over. Stephen Quinney University of Edinburgh School of Informatics Andrew J.
