The current module s verification result is returned to Linux-PAM. Linux-PAM checks the retrieved verification result. If the verification result is successful, go back to step 3 to load the next module, and then repeat step 4 until all modules have been loaded. If all modules evaluated success, the user is authenticated. Proceed to step 5. If a verification result fails, the user is not authenticated; head to step 5. Return the result of the verification to the PAM-enabled application. If the PAM-enabled application sees that the user is authenticated, it will allow usage to its service. If the PAM-enabled application sees that the user is not authenticated, deny the usage of the application s service.

Assume that both the SSH server and cron daemon from Figure 8-1 are PAM-enabled. Instead of maintaining the sshd_config file for the SSH server and the cron.deny file for the cron daemon, the administrator will use the PAM configuration files of each service and will specify the needed modules on their PAM configuration files. Linux-PAM will handle the authentication process. This shows the advantage of PAM over using separate authentication methods for each application. The administrator will only configure the PAM configuration files of the PAM-enabled applications to use the needed modules to authenticate users. You will learn that starting in the next section.

In Figure 8-2, each PAM-enabled application has its own rules. These rules are used by Linux-PAM to know what modules to load to determine whether to allow or deny a user access to the application. A rule is composed of a name, a type, a control value, and a module. If the module can take arguments, that is also included on the rule. Here is the syntax of a PAM rule: servicename servicetype control modulepath modulearguments where servicename is the name of the PAM-enabled application. The servicetype is the management group that will be used for this rule. The control part of the rule will define the resolution that PAM will use evaluating this rule. The modulepath are the modules that will be used for this rule. The modulearguments is optional and will hold the arguments that the associated modules can use. Here is an example of a rule taken from the cron daemon s PAM configuration file called crond in /etc/pam.d: auth sufficient pam_rootok.so In the sample line, the servicetype is the auth management group the control part is sufficient, and the modulepath has pam_rootok.so as the module to be used for this rule. There is no servicename part for this rule, because that is replaced by the configuration file s name. If you like, you can add it like this: crond auth sufficient pam_rootok.so PAM will use this rule without a hitch. Composing rules with a servicename part is necessary if you have to put all of your PAM rules inside a single configuration file. This configuration file is called pam.conf, and it must reside inside the /etc directory. The other way to make rules for each PAM-enabled application is to create separate text file with the same name as the application and put the rules in it. These files must reside inside the /etc/pam.d directory. This is the method used in CentOS and other modern Linux distributions. Looking back at Figure 8-2, the SSH server has its rules in the sshd file while the cron daemon s rules in the crond file. If the pam.d directory exists, Linux PAM will ignore the rules inside the pam.conf file if there is one on the /etc directory. Some rules inside the crond PAM configuration file are in Listing 8-6.
