openATTIC authentication failure after creating multisite configuration

SUSE Enterprise Storage 5


Configure Multisite Object Gateways per SUSE documentation at:

The default zone group was removed as instructed with:
cephadm:~ # radosgw-admin zonegroup delete --rgw-zonegroup=default
cephadm:~ # radosgw-admin user list

It was noticed that under settings in the openATTIC dashboard, the Object Gateway API  will no longer connect with the admin user. It only connects if given the user that was created as part of the multisite gateway setup.

The openATTIC Object Gateway API shows the following error:
Object Gateway - Authentication failed
This module cannot be loaded due to an authentication problem while connecting to the RGW S3 API
Please verify that:
* Object Gateway Access Key, Secret Key and Admin User setting are defined correctly
* Alternatively check that DeepSea is return the correct RGW information by running the following command on the Salt master: #salt-run ui_rgw.credentials

salt-master:~ # salt-run ui_rgw.credentials
    <ADMIN_ACCESS_KEY removed>
    <ADMIN_SECRET_KEY removed>
    - http://rgw1:80/admin
    - http://rgw2:80/admin

NFS Ganesha providing access to object buckets doesn't work because it defaults to using the admin account as well.


1. Retrieve the current rgw object gateway admin credentials
cephadm:~ # KEYS=$(salt-run ui_rgw.credentials | grep -A1 _key)
cephadm:~ # ADMIN_ACCESS_KEY=$(awk '{print $2}' <<< $KEYS)
cephadm:~ # ADMIN_SECRET_KEY=$(awk '{print $4}' <<< $KEYS)

2. Recreate the rgw object gateway admin user with the retrieved credentials
cephadm:~ # radosgw-admin user create --uid=admin --display-name='Admin User' --admin --system --access-key=$ADMIN_ACCESS_KEY --secret=$ADMIN_SECRET_KEY
cephadm:~ # radosgw-admin user list


The object gateway admin user was removed during the multisite configuration and needs to be recreated.
