Any LDAP address book software?


Do not read this sign.
I'd like to keep my family's address book someplace useful and acessible like from an LDAP server.

I'd made some really cool XML/XSL solutions but I can only use that on my Windows IE (still the best web-browsing platform). I'd like to use the addresses on my other platforms--most importantly, Mac OS X.

Has anyone seen any good solutions for managing an LDAP directory of names and addresses? Some applications? Some PHP scripts? Some mySQL databases?

Seems most of the LDAP stuff I find has to do with authenticating users, etc, not just address book stuff.
