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.
