This step by step guide is derived from the installation instructions which you can find at yourdomain.com/doc/acs-authentication/ext-auth-pam-install.html. It is build upon PAM 0.77 (tested) and does not work on RedHat Linux Enterprise 3 (using PAM 0.75). It makes use of the ns_pam module written by Mat Kovach. The instructions given in here do work with PAM LDAP accordingly and differences will be shown at the end of the file.
Install ns_pam. Download and install ns_pam
[root aolserver]#cd /usr/local/src/aolserver/
[root aolserver]#wget http://braindamage.alal.com/software/ns_pam-0.1.tar.gz
[root aolserver]#tar xvfz ns_pam-0.1.tar.gz
[root aolserver]#cd ns_pam-0.1
[root ns_pam-0.1]#make install INST=/usr/local/aolserver
[root ns_pam-0.1]# cd /usr/local/src/aolserver/ wget http://braindamage.alal.com/software/ns_pam-0.1.tar.gz tar xvfz ns_pam-0.1.tar.gz cd ns_pam-0.1 make install INST=/usr/local/aolserver
Configure ns_pam. Configure AOLserver for ns_pam
To enable ns_pam in AOLServer you will first have to edit your config.tcl file and enable the loading of the ns_pam module and configure the aolservers pam configuration file.
ns_param nspam ${bindir}/nspam.so
to enable the loading of the ns_pam module.pam_domain
in the section ns/server/${server}/module/nspam
with aolserver
[root ns_pam]#cp /var/lib/aolserver/service0/packages/acs-core-docs/www/files/pam-aolserver.txt /etc/pam.d/aolserver
Configure PAM Radius. Configure and install PAM Radius
You have to make sure that pam_radius v.1.3.16 or higher is installed, otherwise you will have to install it.
[root ns_pam]#cd /usr/local/src/
[root src]#wget ftp://ftp.freeradius.org/pub/radius/pam_radius-1.3.16.tar
[root src]#tar xvf pam_radius-1.3.16
[root src]#cd pam_radius
[root pam_radius]#make
[root pam_radius]#cp pam_radius_auth.so /lib/security/
[root pam_radius]# cd /usr/local/src wget ftp://ftp.freeradius.org/pub/radius/pam_radius-1.3.16.tar tar xvf pam_radius-1.3.16 cd pam_radius make cp pam_radius_auth.so /lib/security/
Next you have to add the configuration lines to your Radius configuration file (/etc/rddb/server). For AOLserver to be able to access this information you have to change the access rights to this file as well.
[root pam_radius]#echo "radius.yourdomain.com:1645 your_radius_password >>/etc/rddb/server
[root src]#chown service0:web /etc/rddb/server
