Fix for Incorrect Retention of Previous Resource Sharing Policy When Switching Between General and Selective Policies

[BimsaraBodaragama]

Purpose

Ensure that when a user is switched between general and selective resource-sharing policies, the previous policy is removed to prevent conflicts.

Goals

• Prevent users from retaining attributes related to both general and selective resource-sharing policies.
• Improve consistency when re-sharing users across organizations.

Approach

• Implement a check to remove the previous resource-sharing policy when switching between general and selective policies.
• Modify the re-sharing logic to enforce the replacement of existing policies instead of appending a new one.
