PAM

LL::NG can use Pluggable authentication module as a simple authentication backend.

You have to install the corresponding Perl module.

For CentOS/RHEL:

yum install perl-Authen-PAM

In Debian/Ubuntu, install the library through apt-get command

apt-get install libauthen-pam-perl

In Manager, go in General Parameters > Authentication modules and choose PAM for authentication.

Then, go in PAM parameters:

• Authentication level: authentication level for PAM module
• PAM service: the PAM service to use (default: login)
