Before deploying LDAP Proxy, you must estimate the hardware requirements for achieving the optimal performance out of your Proxy setup. The performance of LDAP Proxy depends on multiple factors regarding how an enterprise plans to use it. Some of the factors to take into consideration for your estimation are:
Number and type of concurrent LDAP operations to be performed
Type of policies going to be configured for LDAP Proxy
Type of hardware (for both LDAP Proxy server and Back-end server):
Processor
RAM
Number of CPU
Once you have gathered the above mentioned information, you can refer to Section 2.0, Sizing Guidance for Deploying LDAP Proxy On-Premise.
