Cadaver does not see remote shares

[PVince81]

Steps to reproduce

1. Setup two servers "localserver" and "remoteserver".
2. On "localserver" enable ext storage
3. On "remoteserver" share a folder "testshare" with link and allow upload
4. Mount "testshare" on "localserver" using server to server sharing
5. Open cadaver with "http://localserver/remote.php/webdav"
6. ls from the root

Expected result

ls should show "testshare" in the list.

Actual result

"testshare" does not appear.
Even worse, doing a mkdir testshare creates an empty folder "testshare" that appears in the data dir.

More info

This is with OC 7 git master 81ecbbb

Note that using WebDAV through the web UI or through KDE's Dolphin correctly displays that folder.

Local shares do not seem to be affected.

It seems that somehow the code that mounts remote shares is bypassed for some strange reasons when using Cadaver (cadaver-0.23.3-70.1.2.x86_64)

Setting to OC 7 CE as this could cause breakage in the file structure (CC @karlitschek @craigpg)

I'll try and debug to find what the difference is between the call from Dolphin and Cadaver.

[PVince81]

It's very weird, it looks like user_id is not defined in the user session, so the sharing mount manager doesn't do anything. It almost looks like the session through cadaver is only half initialized. Still, we're able to see the other files.

[PVince81]

It looks like cadaver is re-authing the session for every call where Dolphin seems to be reusing the session.
The issue happens when re-authing the session: the external mount manager calls setup in app.php which happens when loadApps is called. But that seems to happen too early, before the session is even initialized.

I'll try and move the external mount manager setup to be done during a setup hook.
