Scott or others,

The following works, but it's returning length = 4096 characters
instead of the length of the attribute.  The code in _fusemodule.c
appears to handle setting the length correctly from the string
returned from the read function.  Any ideas?

    def read(self, path, length, offset):
        print "ldapfs:read:read(%s, %d, %d)" % (path, length, offset)
        if length == 0:
            return ""

        pl = path.split('/')
        assert pl[0] == ''             # should have split on leading /
        rdns = pl[1:-1]
        rdns.reverse()
        attr =  pl[-1]
        search_dn = ','.join(rdns + [self.basedn])
        result = self.conn.search_s(search_dn,
                                    ldap.SCOPE_SUBTREE,
                                    '(objectClass=*)', [attr])
        attr_val = result[0][1][attr][0]
        print type(attr_val)
        print attr_val
        print len(attr_val)
        return attr_val[offset:offset+length]
