[horde] Auto Populate Default Identity

[Cliff Hayes]

I am a new to horde and am trying to set up a server.
I need default identity to be populated automatically.
I have searched archives and what I have found has not helped.
hooks.php.dist doesn't mention identities.
And http://wiki.horde.org/CustomizingPreferences is no longer useful 
because of a note at the top stating the hooks format has changed.
Please advise.
Thanks in advance.
