Hi All,
 
I am new to this mailing list and am about to ask a probably very silly question.  Please feel free to direct me to resources that'll help me answer them.
 
I want to setup the following:
 
Gateway [server1]
       -  nic1 = Internet
       -  nic2 = DMZ [server2]
       -  nic3 = Router w/ Wireless -> App Server [Server3] (FREERADIUS SERVER HERE) -> Local Lan
 
I read a lot about both Freeradius and LDAP and cannot determine if either can accomplish my goals.
 
What I want is:
 
1)  1 central place where all user authenication takes place:   SSH, Shell Access, Samba, OpenVPN, Mumble, Any other app that requires user administration.
2)  This information stored in a SQL type database so that I can build my own custom apps to report on user usage, performance ect.
3)  My router has wireless and I have enabled the security features.  I would still like authenication to take place before a wireless user is allowed on the network.
 
For example,
 
Currently, I have this: Router w/ Wireless -> App Server [Server3] + Local Lan
 
I want this: Router w/ Wireless -> App Server [Server3] -> Local Lan
 
Is Freeradius the best approach for my needs?  Do I need anything else?
