libcurl with NSS CA-certificate problem

Hello,

As part of a project we decided to use the libcurl library in our c++
program to handle IMAP communication on a windows platform, because of
licencing issues we have compiled a version of libCurl using NSS but
without OpenSSL support.
Right now we managed to have a simple non encrypted connection and to
encrypt the connection using the server certificate by using the
curl_easy_setopt(curl,CURLOPT_SSL_VERIFYPEER,0L).

But whenever we try to use the peer verification the connection is cut
before the SSL handsake begin and we get an error:
"curl_easy_perform() failed: Problem with the SSL CA cert (path?
access rights?)"
verbose give us "failed to load libnssckbi.so"

and if we pass CURLOPT_SSLCERT with my certificate name we get the
same error but this time we have the line "Initializing NSS with
certpath: sql:mySSL_DIR_path"

we tried using the curl command line equivalent to our program :
curl.exe -v imaps://url --user "user:pwd"

We figured that they is a problem with our NSS database but can't
figure out what, we can read the database with Certutil.exe. do you
see anything wrong with our process?

Also is it normal that on a system windows NSS search for
libnssckbi.so (we have nssckbi.dll in our path).

Hoping you can help.

Sincerely

Maxime Legros
