403 Access Denied for customers in Magento REST API

Question

I am getting 403 Access Denied error for http://www.example.com/rest/api/customers in Magento 1.9.2.4. Everything in admin side rest & admin roles and resources are proper and set to "All". Though http://www.example.com/rest/api/products is working but not able to fetch customers and getting Access Denied.

I tried with other Magento version setups also in same server but all gives 403 Access Denied error for customers and working fine for products. Server is using SUPHP. What could be solution?

Thanks
