2. Workflow Disruptions: When users can't access what they need, it can slow down their work and create delays.
3. Security Risks: Mistakes in member aliasing can accidentally let unauthorized people gain access to sensitive information or resources.
4. Increased Troubleshooting: System administrators may have to spend extra time fixing these errors, which takes away from other important tasks.
