This is the README for pam_unix in Linux-PAM-0.53.
--------------------------------------------------
pam_unix comes as four separate modules:
pam_unix_auth: authentication module providing
pam_authenticate() and pam_setcred() hooks
NO options are recognized. Credential facilities are trivial
(function simply returns)
pam_unix_sess: session module, providing session logging
"debug" and "trace" arguments are accepted, which indicate the
logging-level for syslog.
"debug" -> LOG_DEBUG [ also default ]
"trace" -> LOG_AUTHPRIV
pam_unix_acct: account management, providing shadow account
managment features, password aging etc..
NO options are recognized. Account managment trivial without
shadow active.
pam_unix_passwd: password updating facilities providing
cracklib password strength checking facilities.
if compiled, the default behavior is to check passwords
strictly using CrackLib. This behavior can be turned off
with the argument
"strict=false"
invalid arguments are logged to syslog.
