[horde] Multiple calendars over Active Sync on Android 5 not working anymore?

[Michael]

Hi,
some time ago I have been testing an Android 4.4 device to sync my Horde
calendars over ActiveSync. Multi calender support worked quite good.

Now I got a Nexus 5 with Android 5.0.1 and syncing multiple calendars
seem not to work anymore.
Is that an issue on Android side, or do I need to investigate in
searching the issue in my Horde installation?

Thanks
Michael
