Maximum Size Quota

Hello Team,

We have integrated one WCF application in Identity manager. Few of the methods are working fine. for getalluser method which list the all users, we are facing issue in debugger, 

"The maximum message size qouta for incoming messges (65536) has been exceeded. To increse the qouta, use the MaxReceivedMessageSize property on the appropriate binding element."

Can anyone please help me out here how can i increase the size of the incoming messages?

we are using identity manager 8.1.2
