How to mount WebDAV to virtual drive with specified permission

Hi,

I am using mount_webdav to mount the URL to virtual drive.

mount_webdav http://xxxxxx my-local-folder

After that, I can see the files and directories in mounted drive with permission 0700, which current user has read, write and execute permissions, others have no access.

My question is, how do I mount it with default permission 0755?

And, the manual say that "

The user and group IDs for all files and directories are set to unknown, and the permissions default to

read, write and execute for user, group and other.

"

Which is not true?

Thank you!
