AD integrated ejabberd

Dear All,
I have successfully integrated AD with ejabberd. I am able to view all the users having mail configured (Exchange integrated) on AD in the web admin interface with administrator as admin user. But I have some problem :
1. I am not able to login to chat client (jwchat,ijab,spark,pidgin) not with administrator login nor with user login.

Please help me to login to chat client....

I am attaching the configuration of my ejabberd

override_global.

override_local.

override_acls.
