PAM_ACCT_MGMT(3)            Linux-PAM Manual            PAM_ACCT_MGMT(3)

NAME         top

       pam_acct_mgmt - PAM account validation management

SYNOPSIS         top

       #include <security/pam_appl.h>

       int pam_acct_mgmt(pam_handle_t *pamh, int flags);

DESCRIPTION         top

       The pam_acct_mgmt function is used to determine if the user's
       account is valid. It checks for authentication token and account
       expiration and verifies access restrictions. It is typically
       called after the user has been authenticated.

       The pamh argument is an authentication handle obtained by a prior
       call to pam_start(). The flags argument is the binary or of zero
       or more of the following values:

           Do not emit any messages.

           The PAM module service should return PAM_NEW_AUTHTOK_REQD if
           the user has a null authentication token.

RETURN VALUES         top

           User account has expired.

           Authentication failure.

           The user account is valid but their authentication token is
           expired. The correct response to this return-value is to
           require that the user satisfies the pam_chauthtok() function
           before obtaining service. It may not be possible for some
           applications to do this. In such cases, the user should be
           denied access until such time as they can update their

           Permission denied.

           The authentication token was successfully updated.

           User unknown to password service.
