pidgin-sipe now compiles without telepathy support, so to use "Office Communicator" protocol users had to use telepathy-haze. But telepathy-haze has problems with accepting certificates https://bugs.freedesktop.org/show_bug.cgi?id=23491. So, idea is that if pidgin-sipe supports telepathy backend directly - give it to users. Reproducible: Always
