Check Existing Issues

• I have searched for all existing open AND closed issues and discussions for similar requests. I have found none that is comparable to my request.

Verify Feature Scope

• I have read through and understood the scope definition for feature requests in the Issues section. I believe my feature request meets the definition and belongs in the Issues section instead of the Discussions.

Problem Description

When the feature to introduce user sharing was created, no flag was created to disable it. Now individual users can share to other individual users irregardless of group access permissions

Desired Solution you'd like

Create a feature flag via environment variable that disables USER Sharing via the access control ui file https://github.com/open-webui/open-webui/blob/main/src/lib/components/workspace/common/AccessControl.svelte and the API side of requests to prevent the payload to each individual ACL configuration for models, knowledge bases, skills, etc

Alternatives Considered

Issue creates burdensome permission issues
