Description:
Hi,

I used LOO 6.1 and I used it to sign documents (ODT and PDF) with my certificate (self-signed). I used a certinomis certificate too in LOO 6.1.

Since 6.2, my certificate doesn't work anymore.

When I use "sign a document", I choose my certificate as usual, and when I click on the sign button, nothing happens.

Normaly, it should invoke the use of the certificate installed in windows and Windows should show a dialog asking for the pin (in the case of certinomis usb certificate) or the password (in the case of my self-signed certificate).

All certificates worked fine in Loo 6.1 (On my boss's computer I had to let Loo 6.1 to allow him to sign documents, so it blocks all updates of LibreOffice on his computer)

I've tested it with Loo 6.3.2.2 (x64) on windows 10 with no success.
The same certificates work fine when i sign an dwg file with Autocad on the same computer

May be a problem whith windows but I hadn't found a way to make it work with LOO 6.2 or 6.3


Steps to Reproduce:
1. Open and save a LibreOffice document (writer)
2. Sign the document
3. choose a certificate installed in windows with a password

Actual Results:
no dialog asking for password or pin code (certinomis usb digital certificate)

Expected Results:
a windows security dialog asking for password of the certificate used


Reproducible: Always


User Profile Reset: Yes



Additional Info:
when i click on the display to see details of the certificate, Loo tell me that the certificate is correct and valid.
