External storage: admin should be able to select the global credentials of a user for authentication purposes

[j-ed]

Expected behavior

As an administrator you can choose between different authentication mechanisms if you want to set-up default external storages for your users without even knowing the users password.Therefore it should also be possible to choose Global credentials of a user for authentication purposes.

Current behavior

As an administrator you can choose between the following authentication mechanisms if you set-up default external storages for your users. Unfortunately one option seems to be missing, the Global credentials of a user setting so that a user needs to enter the credentials only once and not per share.

...
User entered, store in database -> credentials need to be entered bythe user per share
Global credentials              -> global credentials (entered by the admin)
Global credentials of user      -> missing option!

Steps to reproduce

1. Login as an admin
2. Choose Admin -> External storages and check-out the available authentication mechanisms

Cheers,
Simon

I guess this makes sense, yes. :)

The issue has still not been fixed in Nextcloud v13.0.6.
