pam_chauthtok


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.
