Don't see the account type pop-up in the add user panel in Server

Question

My 10.8 server was set up out-of-the-box to host network accounts via Open Directory. No Prob. We created various users for my laboratory, all works swimmingly.
Today, for fun, giggles, etc, I've bound the server to my uni's Active Directory server - my hopes, to be able to add users to my laboratory's network/server services setup from the master super authentication server.
The AD server was bound via the Users & Groups -> Login Options -> Network Account Server button (it shows 'Multiple' now- the original OD server, set up via the initial server configuration helper utility, and the uni's AD server)
I go into Server's Users panel I see Local Users, Local Network Users, and Users from <Active Directory Domain>
The Directory Utility shows the AD Domain in its search path.
If I enable network logins on the server (In the Users & Groups System Preferences) any ol' user from the AD server can log in, it creates a mobile, managed directory, etc. All is OK. I've disabled this as I'd rather not folks log into the server... just me the admin.
I want, instead, to 'import' user accounts, by hand, from the AD server, as is shown/enunciated here:
http://help.apple.com/advancedserveradmin/mac/10.8/#apd9ff42f68-0148-40df-a8a8-a 66ad0d291b9
When I hit step #3, eg, selecting the 'Type' of account to add I fail to see the 'Type pop-up menu'. Reading on -
If you don’t see the Type pop-up menu, your server isn’t connected to a network account server in your organization.
yet, I most certainly am, as per the above.
Any thoughts here?

I confirm that Java Platform plugin can't be found on Thunderbird addon manager neither on mozilla website.
Maybe the plugin is handled by Java now?
On Linux (Debian Wheezy) I installed these two packages and works fine:
default-jre icedtea-plugin
Here's a nice java tester:
