Some of us want to use their own servers that have a self-signed SSL certificate for synchronization with the Exchange client from the Jolla store. There should be a way to accept these certificates while setting up the synchronization.

I would suggest to widen this request not just to Microsoft Exchange SSL certificates but also to Jabber/XMPP and email certificates. Currently it's not possible to use self-signed SSL certificates for any of these services and there is even no error message when you try to use it.

For Jabber/XMPP there is a workaround (using the command line) at IMAPS/SMTPS e-mail already works with self-signed certificates (at least for me)

A proper deployment of Exchange should have a properly trusted certificate. If you have a Exchange server that isn't trusted you are likely to also be willing to do the following: a) Save a copy of the certificate. b) Copy it to the device into /etc/ssl/certs.

You might need to create a symlink inside the same directory with a hash of the certificate: "ln -s yourcert.pem `openssl x509 -hash -noout -in yourcert.pem `.0"

I'm aware that this is just a workaround. Jolla is aware of this and are working on addressing this in general AFAIU.

Sometimes you want a CA cert or even roll your own cert if you don't trust the big authorities.

Thanks, works fine for me now. (actually it's a Zarafa server, not an Exchange server)

@slaveriq YES. Actually a self-signed certificate, properly distributed over a secure channel is safer than one bought from an authority.

See this for XMPP. Possibly working for Exchange as well.

Unfortunately that one only works for Jabber/XMPP. not for Exchange

Fixed with update to SailfishOS (Maadajävri) from 27-Dec-2013

Can we get a few more confirmations and close the issue?

BTW: The device should not accept any self-signed certificates without user confirmation! Otherwise we do not need any certificates as then there is no security anyway.
