We are experiencing some odd slowness issues with our LDAP Proxy Server. When using a main Application that get’s used a lot with LDAP here at our school, normal login was under 2 seconds. When we changed the Application to use the Duo Proxy LDAP Server, we saw that it would take up to 35 seconds before we would see the push on our phone. Not only does it do it with the phone, but same when logging in with a hardware token, and phone call. After doing the 2nd form of authentication, it logs us in right away. At other times, we have seen it go as quickly as 1-5 seconds. The Server that is running the LDAP Proxy Server is on the quickest hardware we own, so we know it’s not hardware related.
Are plan for now is add a 2nd Proxy server and do some load balancing, but we were unsure if that will really help or not.
The Server that is running the LDAP Proxy is Windows Server 2016, with 4GB of RAM, and 2 core, on flash memory.
Has anyone experienced this, or any ideas ?
