[Netdisco] Require Auth for Network Access

[Nikolaos M. <nm...@ad...>]

Hi all,

I would like to request your advice on the following subject (it's a bit 
off-topic, I understand, but I believe the list members might be able to 
provide the right feedback).

We would like to enforce authentication for all clients connecting to 
our network (wired or wireless), so that when a client connects, the 
client will not be able to use the network unless it successfully 
authenticates (e.g. via web) with a valid account (LDAP-based).

We have a network based mainly on Cisco 2950/2960 switches.

We are running a central LDAP Server (openldap) where we hold user 
accounts, which are used for mail, ftp, web, Shibboleth access.

How can we implement this policy enforcement? Of course we could buy 
Cisco ISE, but I would like to look into other solutions, mainly open 
source, if possible.

Please advise.

Thanks and Regards,
Nick
