I think I have found all related info on this bug... it's actually being caused by empathy not asking to accept the CA certificate at connection time. Therefore you need to have a local copy of your(s) OC server(s) certificate(s).
Here is my starting point, more specifically comment #19 https://bugzilla.redhat.com/show_bug.cgi?id=754395#c19 That eventually leads to: https://bugzilla.redhat.com/show_bug.cgi?id=579116#c3 Which interestingly relates as well to an existing launchpad but: https://bugs.launchpad.net/ubuntu/+source/telepathy-haze/+bug/417432 ---- WORKAROUND: I ended-up finally being able to resolve the issue, hopefully for good! I did the following (found from a previous post on redhat bugzilla): openssl s_client -showcerts -connect MY_OFFICE_OC_SERVER_FQDN:sip-tls I've copied the certificate portion to a file named "MY_OFFICE_OC_SERVER_FQDN.pem" in "/usr/share/purple/ca-certs". The relevant info was such as below. Note that I was having two certificates being offerred therefore in the file I also have the related header such as:: 0 s:/DC=aa/DC=bb/DC=cc/DC=dd/CN=blabla i:/C=XX/O=OfficeName/CN=blablaRootCA -----BEGIN CERTIFICATE----- blabla -----END CERTIFICATE----- 1 s:/DC=aa/DC=bb/DC=cc/DC=dd/CN=blabla i:/C=XX/O=OfficeName/CN=blablaRootCA -----BEGIN CERTIFICATE----- blabla -----END CERTIFICATE----- And voilĂ ! Now only need empathy to do that automagically. ** Bug watch added: Red Hat Bugzilla #754395 https://bugzilla.redhat.com/show_bug.cgi?id=754395 ** Bug watch added: Red Hat Bugzilla #579116 https://bugzilla.redhat.com/show_bug.cgi?id=579116 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/884628 Title: Cannot login using SIPE, working in pidgin though To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/empathy/+bug/884628/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
