Federated cloud deployments encompass an ever-evolving set of requirements, particularly within areas of industry, commerce and research supporting high-performance HPC and high-throughput HTC scientific workloads. It's an area in which OpenStack really shines, through excellent support for federation protocols and its standard API for the manipulation of infrastructure primitives, but at the same time the reality is that no two deployments are entirely alike - and this can cause problems for both users and operators.
If you're an optimistic sort then you could in fact view this as a strength of the platform, as it means that a given installation can be tailored according to the workload. For example, you might have one installation at a particular institution that's designed for provisioning and presenting interfaces to databases, and another which is developed to run a HPC job scheduler such as SLURM.
Practically speaking though, the fact that each is installed on completely different selections of hardware, each according to the workload, is of no interest to our users. What they do care about is having access to each in a way that isn't bogged down with too much bureaucracy or burdensome tooling. To that end, one of the key themes that overarches almost any architectural discussion with regards to federated cloud workloads is that of authentication and authorisation infrastructure AAI.
The need to provide a secure and compliant solution, yet one which is ostensibly seamless and as pain-free for users, is certainly a challenge - and getting this right is fundamental to a platform's adoption and its success. Fortunately there are myriad tools and technologies available to help meet this.
Keycloak is one such application, and it's one that we at StackHPC have been experimenting with as a proof-of-concept in order to provide the AAI 'glue' between two cloud deployments that we help to operate. A few people have asked us to share our experiences and so this blog post is an attempt at summarising those. Also note that this post focuses on browser-driven interactions, as you'll see that a lot of the redirections make use of WebSSO where a web browser is required.
It's the upstream version of RedHat's enterprise Single Sign-On offering and as such is well supported, developed and maintained. Keystone already has good support for federated authentication in a variety of contexts, and there are existing services such as EGI's Check-in and Jisc's Assent that provide identity brokering using compatible protocols, so why introduce another moving component into the mix?
For us, it was about being able to add another layer of control and flexibility into the authorisation piece. A proof-of-concept federated OpenStack using two disparate deployments was integrated using the aforementioned EGI Check-in solution, and while this worked well we often found ourselves wanting more control over the attributes, or claims, that are presented and subsequently mapped via Keystone as part of the authorisation stage. Let's review how Keycloak fits into the equation.
A user makes a resource request via their service provider, which in return expects them to be authenticated.Sml phone number
When Keystone is configured to use an identity provider IdPthe user is redirected to the IdP's landing page - which in our case is Keycloak. Here the user is presented with a selection of login choices. Depending on their selection, they're then redirected a second time in order to perform the authentication step, and then Keycloak handles the transparent redirection and security assertion back to Keystone.
At this point access is granted, assuming the right mappings are in place to grant membership of the user to a group which has permissions within scope of a project.
[keycloak-user] Custom user registration
On paper this sounds somewhat convoluted, but in practice it's reasonably slick and intuitive from a user's point of view:. In my case in the video abovethe Horizon login page redirected me to a Keycloak instance, which presented me with three authentication options. This provided Check-in with some context, which in turn was passed back to Keycloak, and onwards to Keystone.
As part of this final step, Keystone is configured to map a particular OIDC claim containing my company affiliation to a stackhpc group which has the member role assigned in a stackhpc project, thus granting me access to resources on this service provider. This little demonstration neatly shows one of the immediate benefits of introducing Keycloak into your federation infrastructure - being able to maintain control over a diverse selection of potential authentication sources.
At this point, I have an identity within Keycloak that an administrator can associate with other AAI primitives, including multiple IdPs, groups, security policies, and so on. A little side note on what else is possible with Keycloak, a feature that could be of use even if you aren't interested in delegating authentication to another service.
Thus, it's possible to federate your users with something such as Active Directory and at the same time add in another layer of security in the form of two-factor authentication.
Once a user has first signed up to Keycloak, either directly such as via an invitation linkor indirectly by delegation to another configured IdP, the user can login to Keycloak and associate their login with an authenticator. With that in place, they can then access cloud resources on a given service provider using the credentials for their Keycloak account:.Step 1. The user makes a self-registration in the keycloak Step 2.

All validation errors at least for basic types of validations like mandatory fields and format of field value should be shown at once to give user clear idea what have to be filled.
Partial solution is to clone registration flow and move "Profile Validation" action before "Registration User Creation". This will perform basic email and first and last name validation together, but password presence validation is still separate.

It is recommended that you start by upgrading the Keycloak server first and Keycloak adapters second. Before upgrading make sure to read the instructions carefully and carefully review the changes listed in Migration Changes.
Before you upgrade, be aware of the order in which you need to perform the upgrade steps. Also note potential issues that can occur within the upgrade process. In general, you must upgrade Keycloak server first, and then upgrade the adapters. Back up the database. For detailed information on how to back up the database, see the documentation for the relational database you are using.
Testing the upgrade in a non-production environment first, to prevent any installation issues from being exposed in production, is a best practice. If you need to revert the upgrade, first restore the old installation, and then restore the database from the backup copy.
NOTE: Files in the bin directory should not be overwritten by the files from previous versions.Making turaren wuta
Changes should be made manually. If you are using a different configuration file than the default one, edit the migration script to specify the new file name.
If you have changed the profile name, you must edit the upgrade script to change a variable near the beginning of the script. Keycloak can automatically migrate the database schema, or you can choose to do it manually. By default the database is automatically migrated when you start the new installation for the first time. To enable automatic upgrading of the database schema, set the migrationStrategy property value to "update" for the default connectionsJpa provider:. When you start the server with this setting your database is automatically migrated if the database schema has changed in the new version.
To enable manual upgrading of the database schema, set the migrationStrategy property value to "manual" for the default connectionsJpa provider:. When you start the server with this configuration it checks if the database needs to be migrated. The required changes are written to an SQL file that you can review and manually run against the database.
After the changes have been written to the file, the server exits. If you have created any custom themes they must be migrated to the new server.Cooling load calculation software
Any changes to the built-in themes might need to be reflected in your custom themes, depending on which aspects you have customized. You must copy your custom themes from the old server "themes" directory to the new server "themes" directory. After that you need to review the changes below and consider if the changes need to be applied to your custom theme.
If you have customized any of the changed templates listed below you need to compare the template from the base theme to see if there are changes you need to apply. If you have customized any of the styles and are extending the Keycloak themes you need to review the changes to the styles. If you are extending the base theme you can skip this step.
