Sets the password (also known as the owner name) of a file in order to restrict access to that file.
Usage
ctutil -setowner file password 0|1
where:
The password parameter is mandatory. Once set, accessing the file requires using the -o option to provide the password.
If the <instance user> attribute is set to a user that is part of the ADMIN group, the file will be accessible regardless of what password is provided.
If <instance user> is not set, or is set to a user that is not part of the ADMIN group, then the password provided must match the one set by -setowner to access the file.
In order to remove an existing file password, the -clrowner command must be used to specify the password with the -o option.
