The LDAP repositories have now moved to a [https://developer.mozilla.org/en/Mercurial Mercurial] [http://hg.mozilla.org/projects/ldap-sdks/ installation]. All development will now take place in that hg repository.
There are two active branches: 'default' (equivalent to the old cvs HEAD), and 'devel-branch-1_4_2' a branch for perldap that was present in cvs.
