2 # /etc/pam.d/common-auth - authentication settings common to all services
4 # This file is included from other service-specific PAM config files,
5 # and should contain a list of the authentication modules that define
6 # the central authentication scheme for use on the system
7 # (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
8 # traditional Unix authentication mechanisms.
11 # here are the per-package modules (the "Primary" block)
12 auth [success=1 default=ignore] pam_unix.so nullok_secure
13 # here's the fallback if no module succeeds
14 auth requisite pam_deny.so
15 # prime the stack with a positive return value if there isn't one already;
16 # this avoids us returning an error just because nothing sets a success code
17 # since the modules above will each just jump around
18 auth required pam_permit.so
19 # and here are more per-package modules (the "Additional" block)
21 # end of pam-auth-update config
