| # /etc/pam.d/common-auth - authentication settings common to all services | |
| # | |
| # This file is included from other service-specific PAM config files, | |
| # and should contain a list of the authentication modules that define | |
| # the central authentication scheme for use on the system | |
| # (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the | |
| # traditional Unix authentication mechanisms. | |
| # | |
| # As of pam 1.0.1-6, this file is managed by pam-auth-update by default. | |
| # To take advantage of this, it is recommended that you configure any | |
| # local modules either before or after the default block, and use | |
| # pam-auth-update to manage selection of other modules. See | |
| # pam-auth-update(8) for details. | |
| # here are the per-package modules (the "Primary" block) | |
| auth [success=1 default=ignore] pam_unix.so nullok | |
| # here's the fallback if no module succeeds | |
| auth requisite pam_deny.so | |
| # prime the stack with a positive return value if there isn't one already; | |
| # this avoids us returning an error just because nothing sets a success code | |
| # since the modules above will each just jump around | |
| auth required pam_permit.so | |
| # and here are more per-package modules (the "Additional" block) | |
| # end of pam-auth-update config | |
