<param name="xml-handler-bindings" value="directory" />
</settings>
</configuration>

why to add lua code? this question is required config file and any lua code,but it has lua code.. the user management lua code so:
local req_domain = params:getHeader("domain")
local req_key = params:getHeader("key")
local req_user = params:getHeader("user")
local req_password = params:getHeader("pass")
local dbh = freeswitch.Dbh("freeswitch","postgres","tttt");
freeswitch.consoleLog("NOTICE","start connect DB...\r\n");
assert(dbh:connected());
dbh:query("select password from users where id="..req_user,function(row)
freeswitch.consoleLog("NOTICE",string.format("%s\n",row.password))
req_password=string.format("%s",row.password)
end);
dbh:release();
freeswitch.consoleLog("NOTICE","info:"..req_domain.."--"..req_key.."--"..req_user.."--"..req_password.."\n");
--assert (req_domain and req_key and req_user,
--"This example script only supports generating directory xml for a single user !\n")
if req_domain ~= nil and req_key~=nil and req_user~=nil then
XML_STRING =
[[<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<document type="freeswitch/xml">
<section name="directory">
<domain name="]]..req_domain..[[">
<params>
<param name="dial-string"
value="{presence_id=${dialed_user}#${dialed_domain}}${sofia_contact(${dialed_user}#${dialed_domain})}"/>
</params>
<groups>
<group name="default">
<users>
<user id="]] ..req_user..[[">
<params>
<param name="password" value="]]..req_password..[["/>
<param name="vm-password" value="]]..req_password..[["/>
</params>
<variables>
<variable name="toll_allow" value="domestic,international,local"/>
<variable name="accountcode" value="]] ..req_user..[["/>
<variable name="user_context" value="default"/>
<variable name="directory-visible" value="true"/>
<variable name="directory-exten-visible" value="true"/>
<variable name="limit_max" value="15"/>
<variable name="effective_caller_id_name" value="Extension ]] ..req_user..[["/>
<variable name="effective_caller_id_number" value="]] ..req_user..[["/>
<variable name="outbound_caller_id_name" value="${outbound_caller_name}"/>
<variable name="outbound_caller_id_number" value="${outbound_caller_id}"/>
<variable name="callgroup" value="techsupport"/>
</variables>
</user>
</users>
</group>
</groups>
</domain>
</section>
</document>]]
else
XML_STRING =
[[<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<document type="freeswitch/xml">
<section name="directory">
</section>
</document>]]
end

Look at fusionpbx source code, it has lots of Lua code.
