Overview
Auth0 limits connection metadata to 10 attributes, which can be restrictive for storing role-claim mappings in RBAC implementations. This article explores alternatives to avoid exceeding this limit.
Applies To
- Metadata
- Role assignments
- Actions
Cause
Auth0’s Management API allows a maximum of 10 metadata attributes in a connection, with each connection limited to 255 characters. While this works for many use cases, organizations with extensive role-based access configurations may exceed this limit, impacting maintainability and performance.
Solution
To handle role-claim mappings effectively without exceeding metadata limits, consider the following alternatives:
Using Auth0 Actions for Role Assignments:
- Implement custom logic in Auth0 Actions to dynamically evaluate user roles based on claims.
- Actions provide greater flexibility by allowing conditional role assignment without storing static metadata.
Grouping Metadata Attributes:
- Instead of storing multiple separate attributes, combine related data into structured JSON objects within the metadata.
- This approach reduces the number of attributes while maintaining readability.
External Configuration Storage:
- Store role-claim mapping details in an external database or API.
- Use Actions to fetch and process role data at runtime, ensuring scalability.
