The default is to use the 8# traditional Unix authentication mechanisms. 9 10# here are the per-package modules (the "Primary" block) 11auth [success=1 default=ignore] pam_unix.so nullok_secure 12# here's the fallback if no module succeeds 13auth requisite pam_deny.so 14# prime the stack with a positive return value if there isn't one already; 15# this avoids us returning an error just because nothing sets a success code 16# since the modules above will each just jump around 17auth required pam_permit.so 18# and here are more per-package modules (the "Additional" block) 19
