    Hello

    I'm trying to connect to our internal Lync / Skype for Business server. But I'm not successful, because of:

    Unable to validate certificate

    The certificate for $server could not be validated. The certificate chain presented is invalid.

    I found an old thread at [83aa475d] from November 2014, but it doesn't have an answer :(

    Our server is using a certificate signed by our internal CA. I am able to fetch the root certificate, which has signed the certificate. But how do I make pidgin use this additional root certificate?

    Thanks,
    Alexander

    Please look up documentation how to install new SSL certificates for your OS. Your log shows that libpurple has been compiled using NSS as SSL plugin and that fails with because it can't validate the server certificate.

    Guessing from the log you likely use Ubuntu, so most likely you would need to have your internal root certificate stored as /etc/ssl/certs/everyware.pem
