Updated pidgin-sipe packages fix skype connections

Publication date: 09 Mar 2016
Modification date: 09 Mar 2016
Type: bugfix
Affected Mageia releases : 5

Description

Microsoft seems to be rolling out a server configuration change that disables 
RC4 stream cipher support in SChannel (== Windows crypto implementation). 
Therefore (some) Office365 servers no longer accept the SIPE ClientHello message 
in the TLS-DSK handshake. The server responds without sending any TLS-DSK GSSAPI 
data back, i.e. sipe-tls is called with an empty TLS record.

Depending on the authentication settings the end user sees one of the following 
error messages:

  o Failed to authenticate to server
  o Incompatible authentication scheme chosen

We need to add (at least) AES-128/256-CBC stream cipher support in SIPE.


This update fix this issue applying the upstream patch.
