Describe the bug

I am encountering an issue with Keycloak versions 26.0.0 and 26.0.1 when attempting to import multiple realms through the file-based import method. Specifically, I am mounting a directory with multiple realm configuration files at /opt/keycloak/data/import/. However, instead of all realms being imported, only one realm is imported repeatedly, overwriting the others.

Version

26.0.1, 26.0.0

Regression

• The issue is a regression

Expected behavior

All provided realms should be imported.

Actual behavior

Only one realm is imported multiple times, overwriting any other realms. There seems to be no pattern based on the alphabetical order or file structure of the realms in the directory.

How to Reproduce?

1. Create multiple realm files (e.g., realm1.json, realm2.json, realm3.json).
2. Mount these realm files to /opt/keycloak/data/import/.
3. Start Keycloak and check the imported realms.

Anything else?

In the logs, I repeatedly see messages like:

[org.keycloak.exportimport.util.ImportUtils] (main) Realm 'realm2' already exists. Removing it before import 
[org.keycloak.exportimport.util.ImportUtils] (main) Realm 'realm2' imported

Additional Details:
When attempting to create a new realm through the Admin GUI after encountering this issue, I receive the following error:

409 Conflict: "Client id 'account-console' already exists"
