For this you have to publish your policy in WSO2 Identity Server and configure WSO2 APIM to validate the incoming authentication requests with IS acting as the entitlement server. You can refer this doc for more information.

What is the APIM version you are using? Do you get any errors? – dilin993 Jan 11 '19 at 06:27

One more thing when configure wso2am with wso2is using ReadWriteLDAPUserStoreManager. when we create users and roles with some permissions in wso2is. Those users and roles get display in wso2am but selected permission doesn't display in wso2am. – Avinash Tiwari Jan 11 '19 at 09:53
