+Subject: [PATCH] data: don't send change updates for login-history
+
+The login-history property of user objects can be quite large.
+If wtmp is changed frequently, that can lead to memory fragmentation
+in clients.
+
+Furthermore, most clients never check login-history, so it's
+wasted memory and wasted cpu.
+
+This commit disables change notification for that property.  If
+a client really needs to get updates, they can manually refresh
+their cache when appropriate.
