The default is to use the 8# traditional Unix authentication mechanisms. 9 10# here are the per-package modules (the "Primary" block) 11auth [success=ok user_unknown=ignore default=2] pam_tally2.so deny=0 unlock_time=0 12# Try for local user first, and then try for ldap 13auth [success=2 default=ignore] pam_unix.so quiet 14-auth [success=1 default=ignore] pam_ldap.so ignore_unknown_user ignore_authinfo_unavail 15# here's the fallback if no module succeeds 16auth requisite pam_deny.so 17# prime the stack with a positive return value if there isn't one already; 18# this avoids us returning an error just because nothing sets a success code 19# since the modules above will each just jump around 20auth required pam_permit.so 21# and here are more per-package modules (the "Additional" block) 22
