Hi, I am using portal for developing a GUI application where we have login page. In the login page the customers are asked to enter user id and password. Once entered, the user is authenticated against LDAP. I wanted to know if it is a good design to use LDAP for end customer authentication with SSO. The customer number can increase by maximum 100 customer per day. Current customer count in the system is 10 million. I am interested to know:
1. Is portal integration with LDAP for such high volume of customer is good practise?
2. Will LDAP performance if the number of hits per second is 5?
LDAP is clustered and requests are load balanced.
