OpenStack Glance Authentication and Changed Swift Password

Input data: OpenStack Icehouse, glance with swift backend. Admin username and password for swift service were changed. After this requests to download some images started to fail.

# glance --debug image-download <image_id> --file image_store_to --progress

returns 500 error for some image_ids and works for other.

in glance-api service log I see that for some reason previous user/password is still in use:
