[imp] IMP 3.2 over https

[Sasa STUPAR]

Hi!

I am trying to run IMP 3.2 over HTTPS but when I try to login I get back
this error:
---------------------
Bad Request

Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.
Hint: https://my-server/
----------------------

I am using like it is suggested, but I have noticed that in the line it
uses http://my-server:443/horde...

Can anyone help me with this ?
