For more information the reader is directed to the -\fBLinux\-PAM system administrators\' guide\fR\. -.PP - -\fBLinux\-PAM\fR -is a system of libraries that handle the authentication tasks of applications (services) on the system\. The library provides a stable general interface (Application Programming Interface \- API) that privilege granting programs (such as -\fBlogin\fR(1) -and -\fBsu\fR(1)) defer to to perform standard authentication tasks\. -.PP -The principal feature of the PAM approach is that the nature of the authentication is dynamically configurable\. In other words, the system administrator is free to choose how individual service\-providing applications will authenticate users\. This dynamic configuration is set by the contents of the single -\fBLinux\-PAM\fR -configuration file -\fI/etc/pam\.conf\fR\. Alternatively, the configuration can be set by individual configuration files located in the -\fI/etc/pam\.d/\fR -directory\. The presence of this directory will cause -\fBLinux\-PAM\fR -to -\fIignore\fR -\fI/etc/pam\.conf\fR\. -.PP -From the point of view of the system administrator, for whom this manual is provided, it is not of primary importance to understand the internal behavior of the -\fBLinux\-PAM\fR -library\. The important point to recognize is that the configuration file(s) -\fIdefine\fR -the connection between applications -(\fBservices\fR) and the pluggable authentication modules -(\fBPAM\fRs) that perform the actual authentication tasks\. -.PP -\fBLinux\-PAM\fR -separates the tasks of -\fIauthentication\fR -into four independent management groups: -\fBaccount\fR -management; -\fBauth\fRentication management; -\fBpassword\fR -management; and -\fBsession\fR -management\. (We highlight the abbreviations used for these groups in the configuration file\.) -.PP -Simply put, these groups take care of different aspects of a typical user\'s request for a restricted service: -.PP -\fBaccount\fR -\- provide account verification types of service: has the user\'s password expired?; is this user permitted access to the requested service? -.PP -\fBauth\fRentication \- authenticate a user and set up user credentials\. Typically this is via some challenge\-response request that the user must satisfy: if you are who you claim to be please enter your password\. Not all authentications are of this type, there exist hardware based authentication schemes (such as the use of smart\-cards and biometric devices), with suitable modules, these may be substituted seamlessly for more standard approaches to authentication \- such is the flexibility of -\fBLinux\-PAM\fR\. -.PP -\fBpassword\fR -\- this group\'s responsibility is the task of updating authentication mechanisms\. Typically, such services are strongly coupled to those of the -\fBauth\fR -group\. Some authentication mechanisms lend themselves well to being updated with such a function\. Standard UN*X password\-based access is the obvious example: please enter a replacement password\. -.PP -\fBsession\fR -\- this group of tasks cover things that should be done prior to a service being given and after it is withdrawn\. Such tasks include the maintenance of audit trails and the mounting of the user\'s home directory\. The -\fBsession\fR -management group is important as it provides both an opening and closing hook for modules to affect the services available to a user\. -.SH "FILES" -.PP -\fI/etc/pam\.conf\fR -.RS 4 -the configuration file -.RE -.PP -\fI/etc/pam\.d\fR -.RS 4 -the -\fBLinux\-PAM\fR -configuration directory\.
