[horde] create ldap accounts with horde4 admin UI

[wodel youchi]

Hi,

I've installed Horde4 with Imp, Turba and Password.

My authentication is made against openLDAP, and I want to be able to create accounts via the horde admin UI, I've made such configuration in Horde3 with the custom function hooks, but now I am unable to do so in Horde4, I've tried modifying the function preauthenticate in hook.php file, but with no luck.

thanks in advance.
