info.magnolia.module.migrationtests.CompareConfigsTest.testCompareUsersWorkspace() currently has a lot of ignores specified:

public void testCompareUsersWorkspace() throws Exception {
        assertTrue(compare("/", RepositoryConstants.USERS, new String[] {
                "/system/superuser/lastaccess",
                "/system/superuser/pswd",
                "/system/anonymous/pswd",
        }));
    }

Although ignoring of password and lastaccess properties is not so bad, bigger problem is with ids of roles which could be added in different order on fresh/updated instance:

• same applies to (userGroups - switched assigned roles and userRoles - switched permissions)

Implement comparison which handle such cases (parse out the report if no better idea). Please move such tests out of CompareConfigsTest to something like Compare*Workspace if it would require new implementation.
