Specifies the User ID (UID) for the root user on the client. If a client sending the mount request is not in the root option list and the mount request comes from UID 0, the number specified with this field is the effective UID. If a client sending the mount request is in the root option list, this field is not used, and the effective UID of the user mounting the resource is 0.
The default value for this field is a UID of 65534, which means that root users on all clients have access to the resource with a user name of nobody. If you do not use the root option and Anonymous UID option for a resource, all users have access to the resource using the UID 65534.
If this field specifies a UID of 0, root access is granted to all hosts.
The following table describes the effects of the Anonymous UID option.
