24 – 28 October looked at the latest version of Updian and shared tips for compiling Perl as well as SSO in Apache.
To begin, Ronny brought us up to scratch on Updian’s latest release. As previously introduced, Updian is a simple update engine for Debian. Compared to v0.2, the new v0.3 has a slicker interface, with sorted lists and generally clearer display of large lists and views. SSH connections can now be specified where the standard port 22 doesn’t apply, and different ports can be used on different servers. To top it off, users of ‘debian-goodies’ can try ’checkrestart’ for a colour-coded view of services for libs that need to be restarted.
Gunnar then introduced the handy PAR::Packer Perl module that compiles Perl scripts with their dependencies linked into a single binary. Platform independent, he showed how to install PAR::Packer on Windows with the help of CPAN and Strawberry Perl. For more info, he recommended http://search.cpan.org/dist/PAR/lib/PAR/Tutorial.pod
Last but not least, Lennart showed how to use ‘single sign on’ (SSO) in Apache with group-specific authentication in an Active Directory environment. Put otherwise, he set out to authenticate a web server via Kerberos ticket and check downstream, whether a user is in a group whose members may access a website. He began by creating a user in Active Directory, and generating a key on the domain controller to which the user is given a principal name. Then he copied the apache2.keytab file to the web server and used kinit to check the apache2.keytab for accuracy, and klist to determine the principal name in advance. Finally, he loaded mod_ldap, mod_authnz_ldap and mod_auth_kerb and configured the browser for SSO access.
