Joining a ContentBridge to Harmonic MediaGrid with
Local User Authentication
For Harmonic MediaGrid ContentBridge software version 5.0 and later, a ContentBridge configured
for Local User Authentication (LUA) authenticates using the omauthremote utility over ssh to any
ContentDirector.
To create passwordless SSH access from the ContentBridge to any Harmonic MediaGrid ContentDirector,
you will set up the first, then the second ContentDirector units, and then set up the ContentBridge. You
can then optionally configure
omauthremote.conf
for primary and secondary authentication servers.
NOTE:
For redundancy authentication, omauthremote is configured to use a primary and
a secondary ContentDirector. By default these are <clustername>-1 and <clustername>-2.
Initial Configuration sets up configuration files on the ContentBridge for LUA. After Initial
Configuration completes, this procedure completes the setup of Local User Authentication.

Creating Passwordless SSH Access from the ContentBridge to
multiple Harmonic MediaGrid ContentDirector units
Set up the first ContentDirector unit. Then you can set up the second unit, and the ContentBridge. Then,
optionally configure
omauthremote.conf
for primary and secondary authentication servers.
Before you begin
Setting up the first ContentDirector requires:
• Harmonic MediaGrid Server version 4.2. or later (4.2.0.2 or later).
• Harmonic MediaGrid ContentBridge software version 5.0 or later, with Harmonic ContentBridge 4000
and Harmonic ContentBridge 2010F hardware models.
1. Log in to the first ContentDirector as root and create a service account named
omauthchk
.
useradd -g wheel -n omauthchk -K UID_MIN=400 -K UID_MAX=499
passwd omauthchk
