PAM_ACCT_MGMT(3PAM) PAM Library Functions PAM_ACCT_MGMT(3PAM)

NAME

pam_acct_mgmt - perform PAM account validation procedures

SYNOPSIS

cc [ flag ... ] file ... -lpam [ library ... ]
#include <security/pam_appl.h>


int pam_acct_mgmt(pam_handle_t *pamh, int flags);

DESCRIPTION

The pam_acct_mgmt() function is called to determine if the current
user's account is valid. It checks for password and account
expiration, and verifies access hour restrictions. This function is
typically called after the user has been authenticated with
pam_authenticate(3PAM).


The pamh argument is an authentication handle obtained by a prior
call to pam_start(). The following flags may be set in the flags
field:

PAM_SILENT
The account management service should
not generate any messages.


PAM_DISALLOW_NULL_AUTHTOK
The account management service should
return PAM_NEW_AUTHTOK_REQD if the user
has a null authentication token.

RETURN VALUES

Upon successful completion, PAM_SUCCESS is returned. In addition to
the error return values described in pam(3PAM), the following values
may be returned:

PAM_USER_UNKNOWN
User not known to underlying account
management module.


PAM_AUTH_ERR
Authentication failure.


PAM_NEW_AUTHTOK_REQD
New authentication token required. This is
normally returned if the machine security
policies require that the password should be
changed because the password is NULL or has
aged.


PAM_ACCT_EXPIRED
User account has expired.
