LDAP databases are usually used in an enterprise setting. The common implementations are Active Directory and OpenLDAP, and we have extensive experience with both.
We can install a RADIUS server that will use your existing user information store. This re-use can help you upgrade your network from "open" and unsecure, to using 802.1X everywhere.
We can configure fail-over, high availability, and "fail-safe" policies for your network.
Network policies can be set for different groups of users (e.g. admin, sales, engineering). Network policies can also be set for different access methods (VPN, WiFi, wired Ethernet, etc.). Our product gives you the flexibility to create the solution you want, without extensive changes your existing systems.
