Hi all, Have downloaded the latest stable source from svn and compiled on CentOS/RHEL5. Other than the PyKerberos dependency not resolving (I located the package via the OS's package manager) everything installed and ran OK until I tried to configure authentication using htdigest (or htpasswd for that matter). Using either of these options the server wouldn't start. I located this ticket on the site, which provides default values for the Apache access methods and looked promising. http://trac.calendarserver.org/projects/calendarserver/ticket/136 I initially tried installing the latest patch available which patched about 5 times, failing in one location. I replaced with the original source and tried patching with the config.py.patch (01/11/07). This applied successfully and the server now runs but I cannot log in and get this error in the server log after attempting to: File "/usr/lib/python2.4/site-packages/CalendarServer/twistedcaldav/config.py", line 210, in update raise ConfigurationError( twistedcaldav.config.ConfigurationError: Default service parameters must be specified in twistedcaldav.directory.apache.DigestDirectoryService using the 'defaultParams' class variable or via the 'defaultServiceParams' module variable in twistedcaldav.config. So I installed the next most recent patch (extensible_config.patch) which partially worked, two hunks failing. Am I on the right track here? Should I even be applying these patches to the current release? Are there additional XML parameters required? Really appreciate any help. Matt
