"No permissions" when copy/paste into Vault about cryptomator

[infeo]

Looking at the log, there are two noteworthy things:

1. the vault resides in a dropbox synced folder
2. compared to a log of a working example, there is not a single create() call for opening a file

I can simulate the second point when playing with FUSE/WinFsp permissions.

@MatthiasArnold Can you test the following?

1. Find out your domain- and username by entering the following into Windows powershell:

"$env:USERDOMAIN+$env:USERNAME".ToUpper()

2. Open Cryptomator and open the vault options of your test vault
3. Activate custom mount options
4. Replace current textfield content by the following string, where D+U must be replaced by the output of step 1

-ouid=1005 -ogid=1005 -ouidmap=1005:D+U

For example, it can look like this:

If you close the vault settings now and unlock, does the problem still occur?

For others with "Access Denied" problems on Windows: See #3250 (comment).

This issue occurs on Windows systems, where multiple AD/Microsoft Entra accounts are logged in simultaneously. See winfsp/winfsp#387 (comment) for technical details.

Hello @infeo,
unfortunately, the "no permission" issue re-appeared when I installed the latest version (1.12.3), this time on all machines - private desktop, work laptop, work desktop. The issue might be related to windows updates, e.g. KB5034763. uninstalling the old version and re-installing last functioning version (1.11.1) did not solve the problem, permission is still denied. on some machines, setting the custom mount flags to "-ouid=1005 -ogid=1005 -ouidmap=1005:AD+USER-ID" helped, but not on all.

With Cryptomator 1.12.0 we introduced vault specific volume types: Every vault can have its own volume type. Please ensure, that WinFsp(Local Drive) is selected as the default volume type in the preferences and the vaults use the "default" volume type in the vault options.
