[horde] Horde auto login

[John Green]

I would like to use turba as a company address book coupled to a openldap
directory.  I have managed to get this working, but I still have to log into
horde before I can access the directory.  I would like to make this
automatically log in, but unfortunately I know little about php programming.
Has anyone come across a plug-in, script, or way to modify existing files to
do this?
