[horde] CalDAV and ldap authentication

[Hanns Mattes]

Hi,

upgrading to latest horde and horde_dav, I can subscribe to the given  
CalDAV-Address, as long, as I use Imp for authentication. But it  
fails, if I use ldap-authentication, which I prefer. It's throwing the  
same sabredav Error ("User foobar at example.com doesn't exist"), I've  
reporte earlier. horde.log is showing Logins success for the given  
user, so AFAICS something on the way to sabredav fails.

Any ideas?

Regards Hanns
