forked from extern/egroupware
using a session for basic auth (not session aware) clients for WebDAV
and GroupDAV. The "sessionid" get's constructed from the basic auth credentials and is not random (as the clients dont store them). --> speeds up the use of *DAV --> stops *DAV handlers to created numerious sessions
