The following resources further explain methods to use and configure PAM. In addition to these resources, read the PAM configuration files on the system to better understand how they are structured. Installed Documentation

  • PAM-related man pages — Several man pages exist for the various applications and configuration files involved with PAM. The following is a list of some of the more important man pages.
    Configuration Files
    • pam — Good introductory information on PAM, including the structure and purpose of the PAM configuration files.
      Note that this man page discusses both /etc/pam.conf and individual configuration files in the /etc/pam.d/ directory. By default, Red Hat Enterprise Linux uses the individual configuration files in the /etc/pam.d/ directory, ignoring /etc/pam.conf even if it exists.
    • pam_console — Describes the purpose of the module. It also describes the appropriate syntax for an entry within a PAM configuration file.
    • console.apps — Describes the format and options available in the /etc/security/console.apps configuration file, which defines which applications are accessible by the console user assigned by PAM.
    • console.perms — Describes the format and options available in the /etc/security/console.perms configuration file, which specifies the console user permissions assigned by PAM.
    • pam_timestamp — Describes the module.
  • /usr/share/doc/pam-<version-number> — Contains a System Administrators' Guide, a Module Writers' Manual, and the Application Developers' Manual, as well as a copy of the PAM standard, DCE-RFC 86.0, where <version-number> is the version number of PAM.
  • /usr/share/doc/pam-<version-number>/txts/README.pam_timestamp — Contains information about the PAM module, where <version-number> is the version number of PAM.
