We have an environment where users first Hit the LDAP Server for authentication and then get IP from DHCP for Accessing Networks. We are using following 1. Cisco Radius (Configure AAA which point to LDAP Server) 2. LDAP Server on Win 2008 R2 for retrieving information from a directory service like Active Directory 3. DHCP Server (windows 2008 R2) We have Windows server 2008 R2 machine which is not joined on Domain. We need to configure the LDAP server on it to get directory services from AD. After authentication it will get the IP Address and use the AD resources. Should i am going to right Direction. Will this setup Work ? Please suggest.Regards, Lalit (Technet)

Why not just point ACS over to the DC directly? Is this "LDAP Server" LDS (or ADAM)? Brandon Wilson - Premier Field Engineer (Platforms)
