UTL_HTTP.SET_AUTHENTICATION for LDAP

Our application is implementing code to interface with internal payment application. We are using UTL_HTTP package to post xml data for their APIs. They have changed requirement to authenticate the request with internal LDAP. We have created user credentials and using utl_http.set_authentication to that API url. We are getting some errors related to SSL and our network team happen to make changes for Djsse.enableSNIExtension = FALSE to resolve issues for other applications. We are not sure what should be changed for our application code to get the request processed.
