Permission Management Issues in Wiki and Google Drive#543

Summary:
Issues arise when trying to reinstate permissions for a user after they have been removed.

Description:
The customer reports that after revoking permissions for a user in both the Wiki and Google Drive, attempts to reassign those permissions result in failure and an error message. This issue seems to persist even after all permissions have been reset.

Steps to Reproduce:

1. Remove all permissions for a user in the Wiki and Google Drive.
2. Attempt to reassign permissions to the same user.

Expected Results:
Permissions should be successfully reassigned to the user.

Actual Results:
An error message is displayed, and permissions are not reinstated.

Additional Notes:
The customer suspects that the permissions may be cached or stored in a location that is not accessible, which could be preventing the reassignment of permissions.

Suggested Actions:

• Investigate the underlying system for permission management.
• Check if permissions are being cached and leading to this issue.
• Examine the error logs to identify the root cause of the issue.
