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

NAME

       pam_acct_mgmt - PAM account validation management

SYNOPSIS

       #include <security/pam_appl.h>

       int pam_acct_mgmt(pam_handle_t *pamh, int flags);

DESCRIPTION

       The pam_acct_mgmt function is used to determine if the users 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:

       PAM_SILENT
           Do not emit any messages.

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

RETURN VALUES

       PAM_ACCT_EXPIRED
           User account has expired.

       PAM_AUTH_ERR
           Authentication failure.

       PAM_NEW_AUTHTOK_REQD
           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 password.

       PAM_PERM_DENIED
           Permission denied.

       PAM_SUCCESS
           The authentication token was successfully updated.

       PAM_USER_UNKNOWN
           User unknown to password service.

NAME

       pam_chauthtok - updating authentication tokens

SYNOPSIS

       #include <security/pam_appl.h>

       int pam_chauthtok(pam_handle_t *pamh, int flags);

DESCRIPTION

       The pam_chauthtok function is used to change the authentication token for a given user (as indicated by the state associated with the
       handle pamh).

       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:

       PAM_SILENT
           Do not emit any messages.

       PAM_CHANGE_EXPIRED_AUTHTOK
           This argument indicates to the modules that the users authentication token (password) should only be changed if it has expired. If this
           argument is not passed, the application requires that all authentication tokens are to be changed.

RETURN VALUES

       PAM_AUTHTOK_ERR
           A module was unable to obtain the new authentication token.

       PAM_AUTHTOK_RECOVERY_ERR
           A module was unable to obtain the old authentication token.

       PAM_AUTHTOK_LOCK_BUSY
           One or more of the modules was unable to change the authentication token since it is currently locked.

       PAM_AUTHTOK_DISABLE_AGING
           Authentication token aging has been disabled for at least one of the modules.

       PAM_PERM_DENIED
           Permission denied.

       PAM_SUCCESS
           The authentication token was successfully updated.

       PAM_TRY_AGAIN
           Not all of the modules were in a position to update the authentication token(s). In such a case none of the user's authentication
           tokens are updated.

       PAM_USER_UNKNOWN
           User unknown to password service.
