Facebook connectivity

[Lord Flame Stryke]

As an additional update to this:  I changed the "Advanced -> Connection 
security" option from "Use encryption if available" to "Requires encryption" 
and it obtained a new certificate and everything now works fine.  Thanks for 
looking into this for me.

If you get an unexplained certificate error you should assume that you
are under a man in the middle attack, until you have convinced yourself
otherwise.

Your first highlighted line indicates that the certificate Facebook
presented is not one you have seen previously from them.  The second
highlighted line indicates that you do not have the root certificate
installed for the alleged signer of the that certificate.

You need to obtain that certificate by secure means, convince yourself
that they are reliable and appropriate people to authenticate Facebook
servers, and install it.

Some information on how to install a root certificate that you trust, on
Windows Pidgin, can be found at

You should not rely on mailing lists like this to tell you whether you
can trust any particular certificate as posters here are not
authenticated or vetted.
