If credentials are not saved for external storage it shows server is in maintenance mode

[Emi94]

Actual behaviour

When accessing an external storage from the android app that doesn't have the credentials saved it shows that the server is in maintenance mode. If I go from a browser, access the external storage, enter the credentials (to be saved) I can afterwards access the folder from the android app as well.

Expected behaviour

The android app should ask for the credentials if they are not saved.

Steps to reproduce

1. Add an external storage to Nextcloud, SMB type in my case and authentication "user entered, stored in database"
2. Access the external storage from the android app first.

Environment data

Android version: OxygenOS 9.0.4 (based on android 9)

Device model: OnePlus 6

Stock or customized system: Stock

Nextcloud app version: 3.5.1

Nextcloud server version: 15.0.5

PS: not sure if this is present on the ios app as I don't have an iphone to test.

@nextcloud/server-triage how can we handle this?

Most likely this additional request for credentials needs to be pushed somehow as status code and then either send the user to the web UI or do the request on your side which could get tricky.

So when entering such a folder server gives back "authorization required" and this pops up a username/password field, and this is then used for this specific folder.

And Android would store this…? Or is this a one time action? How is this handled on web ui?

It needs to be stored on the server. I guess there is some special API endpoint that takes this. In the web UI this is all handled via JS that is injected and does this. And therefore it is not really standardized/documented.

[tobiasKaminsky]

Ah, ok :-)
Then…if you find the time, this should be documented and implemented in server and after that clients can do this.
I guess this is also a problem for windows/iOS? If so, then I'll open up an issue on server to track this?

[MorrisJobke]

@icewind1991 @rullzer Any idea how to properly do this on the storage level? Currently it is a non-standardized way with some JS interferences to allow this.

[tobiasKaminsky]

@nextcloud/server-triage this is still the case, and on client side we cannot do anything right now

I came across this issue today trying to access a few shares through the Android app. I wanted to add a note for anyone else looking for a solution until it is fixed, the comments here gave me an idea for testing. I managed to "get it to work" by changing the external storage from "Log-in credentials, save in session" to "Log-in credentials, save in database." I am using LDAP though so ymmv but this is, at least for me, a work around until a real fix can be found.

[tobiasKaminsky]

@nextcloud/server-triage any idea?
At least a proper error message, so that clients can handle this correct, would be fine.
Please note that this currently affects all clients!

[tobiasKaminsky]

Moved to server.
Once this is done, we can handle it accordingly on all clients.
