Description
Currently KMSACLs is getting reloaded depending on whether kms-acls file is modified or not.
Since the access control is specified by AcccessControlList, the member may contain unix-group or net-group.
If we add a new user to any group, technically the file is not modified but the membership of a group is modified, so we need to reload the kms-acls file.
There are couple of solutions for this.
1. short-term solution: Reload the file periodically (like lets say every 15 minutes).
2. long-term solution: Implement a refreshUserGroupMapping like protocol/servlet so whenever we change membership we can invoke that protocol and we get the updates.
