Hello, I am configuring a client in the KeyCloak admin console, but am
having a trouble to create an client to secure. Specifically, The Base URL
field is wrong (repeated), as I saved in the configuration page.
Please see the two attachments for an illustration of the the issue. This
looks very weird.
As you can see clearly from keycloak2.png, the base URL i typed is
repeated, thus invalid.
Thanks for any information that might be helpful.

New subject: Using KeyCloak with multiple Realms
Dear Stian,
we faced an issue when using KeyCloak with a multiple-tenant service and came up with a
working solution we would like your opinion on.
Our old approach was outlined as follows:
Each of our tenants was assigned a single realm. Within this realm, an
"administrator" user was created that enabled the tenant to full extent within
our application, but not within the KeyCloak realm itself.
Our software utilized the master realms root user to obtain the JSON installation files
for our respective services.
Thus, we ran into the problem of roots ever growing access rights, as described in this
issue:
https://issues.jboss.org/browse/KEYCLOAK-3067
The encoded list of roots rights in the “Authentication” header exceeded 8KB and our web
server was unable to process any requests from this point onward.
To get rid of this problem, we devised a literal workaround: Each realm gets its specific
master user who is entitled with all rights the client “realm-management” has to offer-
one could say we created a local root for each realm. This master now steps up to the hole
left by root and provides the public keys etc. for our services. As its rights are limited
to its own realm, its bearer token remains at a constant, reasonable size.
The (scripted) creation of such a new realm works like this:
We manually added a user in the master realm who has no rights besides creating new
users. We access this user via the admin-cli client and create a new user “creator”.
Creator is then assigned a random password (which is cached) and the role “create-realm”.
In the next step, we access creator and create our new realm, complete with clients,
roles, groups and the two users , the administrator and the master.
After successful creation of the realm, creator has fulfilled its purpose and is deleted.
As he possesses full rights in the newly created realm, his continued existence presents a
potential insecurity with no practical use to justify it.
The big downside of our new approach is the fact that the rights of the master realms root
user still keep growing. So we inevitably lock ourselves out of the mater realm security
console in the long run.
Of course, we’re still able to access each realms console via
/auth/admin/<realm>/console with the master user.
Also, in the issue linked above, you commented that KeyCloak is not meant to be used with
multiple realms. However, if the master realm was actually removed from KeyCloak in the
future, our temporary workaround might yet turn into a long – lasting solution. Are we
right on this part?
Thank you very much for your consideration.

New subject: Using KeyCloak with multiple Realms
I didn't say Keycloak isn't meant to work with multiple realms, but it's
wasn't designed to work with a large number of realms. We considered it
initially, but then figured true multi tenancy would be best introduced by
having multiple instances rather than trying to achieve total isolation
between realms. We don't test how well it scales with a large number of
realms either.
KEYCLOAK-3067, complexity of having a "master" realm and finally the fact
that an admin may be managing realms on a single instance or on multiple
instances we've decided that in the future we'll drop the master realm.
Instead we'll have an option to setup "trust" between realms so an admin
can easily authenticate to a different realm.
To prevent being locked out from the master realm you can remove the roles
from the new realm in the admin composite realm.

Hi Martin, you can just /bword/ at the Admin URL or nothing, it depends.
Take a look at our demo distribution[1]. For example, customer-portal.

Hi, Bruno:
I will try the customer-portal demo. I had made these demo working in
keycloak 1.7, but the same way configured in 2.0, it doesn't seem to work.
I need to look at these modified examples. How to delete a realm in
KeyCloak? I wanted to delete the Demo realm I created and just imported the
realm in the examples/ directory for customer-portal. I can't find a place
I can delete a realm in the Admin console.
Thank you.

Looks like it's a bug in the admin console on how it handles relative URLs.
As you have a root url it should be prefixed to any relative urls, but as
the base url you have is not a relative url it's should have the root url
added. Please create a JIRA for it.
