 **Step 230:** Play with setting filters and adjusting the selected views. Are you able to manipulate reports into the table that do not agree with the shown filter? Do the different indicators of the applied filter remain in sync?
 
 > [!NOTE]
-> You can apply a filter on a column that exists in the white box view but not in the white box view with less metadata. When you apply such a filter and then switch to the view with less metadata, the filter is allowed to remain. This is OK when there is a clear indicator that the filter is still applied and if it is possible (for example with the clear button) to remove all filters.

+### Test 30: Authorization
+
+**Step 10:** This test starts with the situation of test 10.
+
+**Step 20:** In the Frank!Runner checkpoint, add the following to `build/<Apache Tomcat dir>/conf/catalina.properties`:
+
+    application.security.testtool.authentication.type=IN_MEMORY
+    application.security.testtool.authentication.username=Admin
+    application.security.testtool.authentication.password=Nimda
+
+**Step 30:** Start the Frank!Framework.
+
+**Step 40:** Browse to the Frank!Console. You should be allowed to view this without logging in.
+
+**Step 50:** Browse to Ladybug. You should see a login dialog to enter the credentials. After providing these, you should have access to Ladybug.
+
+**Step 60:** Rerun a report. Check that rerunning is allowed and that rerunning succeeds for a report that succeeded when created.
