NAME

       pam_debug - PAM module to debug the PAM stack

SYNOPSIS

       pam_debug.so [auth=value] [cred=value] [acct=value] [prechauthtok=value] [chauthtok=value] [auth=value] [open_session=value]
		    [close_session=value]

DESCRIPTION

       The pam_debug PAM module is intended as a debugging aide for determining how the PAM stack is operating. This module returns what its
       module arguments tell it to return.

OPTIONS

       auth=value
	   The pam_sm_authenticate(3) function will return value.

       cred=value
	   The pam_sm_setcred(3) function will return value.

       acct=value
	   The pam_sm_acct_mgmt(3) function will return value.

       prechauthtok=value
	   The pam_sm_chauthtok(3) function will return value if the PAM_PRELIM_CHECK flag is set.

       chauthtok=value
	   The pam_sm_chauthtok(3) function will return value if the PAM_PRELIM_CHECK flag is not set.

       open_session=value
	   The pam_sm_open_session(3) function will return value.

       close_session=value
	   The pam_sm_close_session(3) function will return value.

       Where value can be one of: success, open_err, symbol_err, service_err, system_err, buf_err, perm_denied, auth_err, cred_insufficient,
       authinfo_unavail, user_unknown, maxtries, new_authtok_reqd, acct_expired, session_err, cred_unavail, cred_expired, cred_err,
       no_module_data, conv_err, authtok_err, authtok_recover_err, authtok_lock_busy, authtok_disable_aging, try_again, ignore, abort,
