The *geo_location.osm* section is only relevant when the *gluon-config-mode-geo-location-osm*
package is used. The *center.lon* and *center.lat* values are mandatory in this case and
define the default center of the map when no position has been picked yet. The *zoom* level
defaults to 12 in this case. *openlayers_url* allows to override the base URL of the
defaults to 12 in this case.
*openlayers_url* allows to override the base URL of the
*build/ol.js* and *css/ol.css* files (the default is
``https://cdn.rawgit.com/openlayers/openlayers.github.io/master/en/v5.2.0``).
It is also possible to replace the default tile layer (which is OpenStreetMap)
with a custom one using the *tile_layer* section. Only XYZ layers are supported
at this point.

password form can be displayed by setting *remote_login.show_password_form*
