Add support to import QGIS auth DB from file

[MTrim]

There is a problem with ArcGIS REST Feature Service in the mobile app. I can see the data in QGIS but not in Mergin Maps.
Somehow there is an authentication problem.

• I am using a Feature Service with ESRI Token as authentication method
• Mergin Maps shows the Layer in the layer tree but no data is visible (Error Message in Screenshot)

I have the same issue, but with the National Land Survey of Finland’s OGC API Features layer, which is authenticated.

Hi guys, thanks for the ticket and sorry for the delayed response. I will forward this ticket to our support team first.

According to Martin Dobias, the problem is related to token authentication. The token is not stored in the QGIS project file but only in the authentication database within your QGIS profile.

To resolve this, the MM QGIS plugin would need to package the authentication details with the MM projects in some way, so that the MM mobile app can access the token.

We are about to start a Mergin Maps project where this feature would be very important. Do you have any idea of the timeline for when this feature could be added to the application? Should i put this request to wishlist?

The plan:

• Import qgis_cfg.xml file if such a file exists within project files
• Make sure to re-import after sync
