Is it possible to share a existing SFTP root directory with another user and he should have only access to the new folder created for his own purpose but not the other existing folders. Also, i need unique SSH key for new user to access the same new folder, should not use existing SSH key.
Can anyone help me to clarify this and please let me know for more details.
AFAIK you can give access to SFTP and can not limit it to the folder level in ACC. If the user has access to the external account with SFTP, he can access the root and subfolders if he knows the path.
