Allowing Multiple Identity Providers With The Same Name In Keycloak

by ADMIN 68 views

Introduction

Keycloak is a popular open-source identity and access management solution that provides a robust set of features for managing user identities and access to applications. One of the key features of Keycloak is its ability to integrate with multiple identity providers, allowing users to log in to applications using their existing identities from various sources. However, a recent issue has been reported in Keycloak that allows multiple identity providers to be created with the same display name under the same realm. This can lead to confusion in the login UI as well as the admin console, making it difficult for administrators to manage and maintain their Keycloak instances.

The Issue

The issue at hand is that Keycloak currently does not enforce uniqueness of identity providers display names within a realm. This means that multiple identity providers can be created with the same name, leading to confusion and potential security risks. For example, if two identity providers have the same name, it can be difficult for users to determine which one to use, and administrators may struggle to manage and maintain their Keycloak instances.

Expected Behavior

The expected behavior of Keycloak is that it should validate and enforce uniqueness of identity providers display names within a realm. This means that when creating a new identity provider, Keycloak should check if a provider with the same name already exists in the realm and prevent the creation of a duplicate provider. This would help to prevent confusion and potential security risks associated with multiple identity providers having the same name.

Actual Behavior

The actual behavior of Keycloak is that it allows multiple identity providers to be created with the same name. This is demonstrated in the attached screenshot, which shows two identity providers with the exact same name configured under the same realm.

How to Reproduce

To reproduce this issue, follow these steps:

  1. Create a new identity provider in Keycloak.
  2. Give the identity provider a display name that already exists in the realm.
  3. Attempt to create another identity provider with the same display name.

Consequences of the Issue

The consequences of this issue are significant. With multiple identity providers having the same name, it can lead to confusion in the login UI as well as the admin console. This can make it difficult for administrators to manage and maintain their Keycloak instances, and may even lead to security risks if users are unable to determine which identity provider to use.

Solution

To solve this issue, Keycloak should be modified to enforce uniqueness of identity providers display names within a realm. This can be achieved by adding a validation check when creating a new identity provider, which checks if a provider with the same name already exists in the realm. If a duplicate provider is detected, the creation of the new provider should be prevented.

Implementation

To implement this solution, the following steps can be taken:

  1. Modify the Keycloak code to add a validation check when creating a new identity provider.
  2. Check if a provider with the same name already exists in the realm.
  3. If a duplicate provider is detected, prevent the creation of the new provider.
  4. Update the Keycloak UI to display an error message if a duplicate provider is detected.

** of the Solution**

The benefits of this solution are significant. By enforcing uniqueness of identity providers display names within a realm, Keycloak can prevent confusion and potential security risks associated with multiple identity providers having the same name. This will make it easier for administrators to manage and maintain their Keycloak instances, and will provide a more secure and reliable identity and access management solution.

Conclusion

In conclusion, the issue of allowing multiple identity providers with the same name in Keycloak is a significant problem that can lead to confusion and potential security risks. By enforcing uniqueness of identity providers display names within a realm, Keycloak can provide a more secure and reliable identity and access management solution. The solution to this issue is to modify the Keycloak code to add a validation check when creating a new identity provider, which checks if a provider with the same name already exists in the realm. This will prevent the creation of duplicate providers and provide a more secure and reliable identity and access management solution.

Recommendations for Future Development

  • Enhance Identity Provider Management: Keycloak should provide a more robust identity provider management system that allows administrators to easily manage and maintain their identity providers.
  • Improve User Interface: The Keycloak UI should be improved to provide a more user-friendly experience for administrators and users.
  • Add Additional Security Features: Keycloak should be enhanced to include additional security features, such as multi-factor authentication and advanced access control.

Future Work

  • Implement Identity Provider Federation: Keycloak should be modified to support identity provider federation, which allows multiple identity providers to be linked together to provide a single, unified identity management solution.
  • Add Support for Advanced Identity Management Features: Keycloak should be enhanced to support advanced identity management features, such as attribute-based access control and advanced authentication protocols.
