| # /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. |
| |
| # here are the per-package modules (the "Primary" block) |
| auth [success=ok user_unknown=ignore default=2] pam_tally2.so deny=5 unlock_time=0 |
| # Try for local user first, and then try for ldap |
| auth [success=2 default=ignore] pam_unix.so quiet |
| -auth [success=1 default=ignore] pam_ldap.so ignore_unknown_user ignore_authinfo_unavail |
| # 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) |
