I tried to setup ActiveSync Autodiscover like it is mentioned in the  
wiki, but it never worked and the Microsoft Analyzer website always  
complained about not finding the /AutoDiscover/AutoDiscover.xml file.

It looks almost the same when trying from my iphone, that only tries  
the POST lines, not the OPTIONS though, but with the same result  
(nothing).

My error log though shows the following for each try:

  PHP Fatal error:  Call to undefined function xmlrpc_server_create()  
in /usr/share/php/Horde/Rpc/Xmlrpc.php on line 32


Just to clarify, the actual ActiveSyncing works without flaws, just  
the autodiscover seems to be missing something.

Also I noticed that Microsoft seems to look for "AutoDiscover" where  
apple is reaching out to "Autodiscover", so I changed and duplicated  
the Alias line in my apache config to catch both cases as I am still  
under the impression that a linux apache is case sensitive, right? But  
even having three alias lines in the config for all options (AD, Ad,  
ad) for "autodiscover" didnt really help.
