[imp] Problems signing a S\MIME message

[Eduardo Juchem]

Hi,

I'm having the following problem with S/MIME signed messages in the CVS
version of IMP:

I have a certificate instaled in a computer at my College. I exported my
key in the pkcs7 format, suported by IMP, and brought it to my computer at
home. Inside Horde, in the menu Options->Mail->S\MIME Options, i could
successfully import my key by importing the pkcs7 file. But when i try to
sign a message with the option "S/MIME Sign Message" in the Encryption
Options box, and try to send this message, i'm having the following error:

S/MIME Error: Need passphrase for personal private key.


S/MIME suport is activated in prefs.php. Am i doing something wrong, or
just missing something before importing the pkcs7 file?

My machine is:
- Fedora Core 1 system;
- PHP 4.3.4;
- Httpd 2.0.48


Any help will be welcome
Thanks in advance
Edu
