TotalNET Advanced Server 5.2 Reference Manual

browse-user

This attribute designates the UNIX user identity for LM-NT-OS/2 realm clients who log in solely for browsing. This attribute defaults to the TotalNET administrator, the admin-user attribute of the system object, which prevents clients from logging in. This attribute has no effect if you set the browse-master attribute to off.

Usage:

tnservice -M [-r realm][-s service] a browse-user=username
