Unfortunately it is not cross platform, it uses the Directory  
Services/Open Directory API provided by Apple.  A pure LDAP  
DirectoryService is on my todo list (using ldaptor[0])  But there are  
design issues blocking that work and I don't have the time to sort it  
all out right now.

I'm sorry that we don't just have something ready for you.  It should  
be possible to use python-ldap[1] without any design changes to the  
twistedcaldav.directory APIs however python-ldap is not an  
asynchronous API so it's performance in our twisted server may be  
suboptimal and require the use of a caching mechanism similar to

P.S. If anyone feels incredibly motivated to pursue any course of  
action along the lines of implementing some sort of LDAP Directory  
Service I'm sure it would be welcome.
