ldap

I have created a function. How do i pass error param in this ldap. if my ldap return 0 record that means userid or password invalid. so when i call this function it will return error =0 or 1 and also employeeNumber,firstname,lastname,sn,cn,mail,uid,userPassword

<cfcomponent displayname="Login" hint="login ">
<cffunction name="logchk" access="remote" output="0" returntype="query" hint="user">
<cfldap name="getusers"
username="cn=Manager,dc=test,dc=test" password="test"
server="test" action="query" port="389"
attributes="employeeNumber,firstname,lastname,sn,cn,mail,uid,userPassword"
start="dc=test,dc=test" filter="employeeNumber=4444">
<cfreturn getUser />
</cffunction>
</cfcomponent>
