TotalNET Advanced Server 5.2 Reference Manual

share-access

This attribute determines share-mode access to the volume in the LM-NT-OS/2 realm. For share mode volumes, a separate, per-volume password, rather than the UNIX user identity, controls access. This attribute defaults to off, which means clients can only access the volume through user-level security mode services. With this attribute on, clients may access the volume through share-level security mode services.

Usage:

tnvolume -M -v volume -a share-access={on|off}
