# /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=1 default=ignore] pam_unix.so nullok_secure
|
# 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)
|
