[CalendarServer-users] HTTP 404 problems

[Rasmus Borup Hansen]

It looks like I've solved the problem. Apparently, you cannot rely on CalendarServer generating the GUIDs. I added the following configuration and haven't had problems yet:

…
    <key>DirectoryService</key>
    <dict>
      <key>type</key>
      <string>twistedcaldav.directory.ldapdirectory.LdapDirectoryService</string>
      
      <key>params</key>
      <dict>
…
	<key>rdnSchema</key>
	<dict>
	  <key>guidAttr</key>
	  <string>entryUUID</string>
…

This reuses OpenLDAP's Universally Unique IDentifiers as Globally Unique IDentifiers in CalendarServer which is probably a nice thing in itself.

Best regards,

Rasmus

I've narrowed it down to requested items not being found in memcached, but the fact that I am a crappy python programmer combined with the fact that getting calendarserver is NOT part of my day job, I have been unable to dig in any further and come up with a cause.

I know that there are some packages that calendarserver sucks in and modifies, and I do not know if memcached is one of those.  Maybe a developer can answer this question?  Can we run calendarserver--any version--against a standard memcached distribution?
