pam_stress - The stress-testing PAM module
pam_stress.so [debug] [no_warn] [use_first_pass] [try_first_pass] [rootok] [expired] [fail_1] [fail_2] [prelim] [required]
The pam_stress PAM module is mainly intended to give the impression of failing as a fully functioning module might.
Put lots of information in syslog. *NOTE* this option writes passwords to syslog, so don't use anything sensitive when testing.
Do not give warnings about things (otherwise warnings are issued via the conversation function)
Do not prompt for a password, for pam_sm_authentication function just use item PAM_AUTHTOK.
Do not prompt for a password unless there has been no previous authentication token (item PAM_AUTHTOK is NULL)
This is intended for the pam_sm_chauthtok function and it instructs this function to permit root to change the user's password without entering the old password.
An argument intended for the account and chauthtok module parts. It instructs the module to act as if the user's password has expired
This instructs the module to make its first function fail.
This instructs the module to make its second function (if there is one) fail.
For pam_sm_chauthtok, means fail on PAM_PRELIM_CHECK.
For pam_sm_chauthtok, means fail if the user hasn't already been authenticated by this module. (See stress_new_pwd data string in the NOTES.)
MODULE TYPES PROVIDED
All module types (auth,
session) are provided.
Memory buffer error.
Access to the system was denied.
The function passes all checks.
The user is not known to the system.
Failure involving user credentials.
Authentication token is no longer valid; new one required.
Failed preliminary check by service.
Authentication token lock busy.
Authentication token manipulation error.
This module uses the stress_new_pwd data string which tells pam_sm_chauthtok that pam_sm_acct_mgmt says we need a new password. The only possible value for this data string is 'yes'.
# Any of the following will suffice
account required pam_stress.so
auth required pam_stress.so
password required pam_stress.so
session required pam_stress.so
