PAM_STRESS(8)               Linux-PAM Manual               PAM_STRESS(8)

NAME         top

       pam_stress - The stress-testing PAM module

SYNOPSIS         top


       pam_stress.so [debug] [no_warn] [use_first_pass] [try_first_pass]
                     [rootok] [expired] [fail_1] [fail_2] [prelim]
                     [required]

DESCRIPTION         top

       The pam_stress PAM module is mainly intended to give the
       impression of failing as a fully functioning module might.

OPTIONS         top

       debug
           Put lots of information in syslog. *NOTE* this option writes
           passwords to syslog, so don't use anything sensitive when
           testing.

       no_warn
           Do not give warnings about things (otherwise warnings are
           issued via the conversation function)

       use_first_pass
           Do not prompt for a password, for pam_sm_authentication
           function just use item PAM_AUTHTOK.

       try_first_pass
           Do not prompt for a password unless there has been no
           previous authentication token (item PAM_AUTHTOK is NULL)

       rootok
           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.

       expired
           An argument intended for the account and chauthtok module
           parts. It instructs the module to act as if the user's
           password has expired

       fail_1
           This instructs the module to make its first function fail.

       fail_2
           This instructs the module to make its second function (if
           there is one) fail.

       prelim
           For pam_sm_chauthtok, means fail on PAM_PRELIM_CHECK.

       required
           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         top

       All module types (auth, account, password and session) are
       provided.

RETURN VALUES         top

       PAM_BUF_ERR
           Memory buffer error.

       PAM_PERM_DENIED
           Permission denied.

       PAM_AUTH_ERR
           Access to the system was denied.

       PAM_CONV_ERR
           Conversation failure.

       PAM_SUCCESS
           The function passes all checks.

       PAM_USER_UNKNOWN
           The user is not known to the system.

       PAM_CRED_ERR
           Failure involving user credentials.

       PAM_NEW_AUTHTOK_REQD
           Authentication token is no longer valid; new one required.

       PAM_SESSION_ERR
           Session failure.

       PAM_TRY_AGAIN
           Failed preliminary check by service.

       PAM_AUTHTOK_LOCK_BUSY
           Authentication token lock busy.

       PAM_AUTHTOK_ERR
           Authentication token manipulation error.

       PAM_SYSTEM_ERR
           System error.

NOTES         top

       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'.

EXAMPLES         top

           #%PAM-1.0
           #
           # 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
