To install the Authen::CyrusSASL Client module for Perl 5, proceed as follows : 1 Unpack the Authen-SASL source archive into a suitable directory with gunzip -cf Authen-SASL-x.xx.tar.gz |tar xvf - 2 Go into the newly created directory with cd Authen-SASL-x.xx 3 Build the module as usual : perl Makefile.PL make make test make install Note that for 'make test' to work, you should have a Sasl Authen/Pwcheck server running with the IP address & secret of the target machine in its clients file. You should also know a username & password in order to test if authentication works OK. Doing a 'make test' will first ask you for each of these. Piotr Klaban
