[horde] Horde with Cpanel - password change and self-registration

[Luan M. Nguyen]

Is there a way users can change their password through Horde?
I would like them to be able to change their password to fits their own. I don't want to go to cpanel everytime my user need to change their password.

And is there away to enable user self-registration instead of I have to add them manually through cpanel?

Thank you very very much
