I had one problem more after the installation: there was no superadmin-user. Neither user "admin" nor my own account had superadmin-privileges. So nobody could give users new rights, do template administration, set general options etc. I found a workaround for this, using MySQL:
$ mysql
mysql> use limesurvey;
mysql> insert into permissions (entity, entity_id, uid, permission, read_p) values ('global', 0, 1, 'superadmin', 1);
mysql> quit;
In this example, I update the permissions for the user with uid = 1 to include the superadmin-permission.
I hope in some way, I can help to improve the contrib - Limesurvey is a very valuable tool.
