Need help for developing chat messenger for our office

Hi,

I was looking in the net for any chat messengers that can be useful for our company, I found Openfire chat server and after installing it, connected to Mysql server(need to connect with LDAP for authentication). Now how can I display all the users in client chat messanger.Is I require any client component to intigrate with Openfire chat server?

Can anybody give some good suggestions?

Regards,
