Hi all,

I'm looking for a solution to grant login into routers/switches using
the active directory logon name. This to have a sort of single-sign-on.

Looking around I've found that all it's possible using Radius,
obviously, but loosing the availability to log all commands written in
the CLI. The only technology can do it, as I know, is tacacs+ that is a
really old protocol and not integrated in any way with kerberos...

Which is your solution? Have u an hint how to solve this thing? I've to
manage about 1,000 routers/switches...

Thanks
Stefano

Cisco Secure ACS supports A/D authentication. It would pass the creds
from the network device to the TACACs server, which then authenticates
directly with the domain. Is that what you are asking?

You can use RADIUS :

Freeradius for Linux ( you will need to add Kerberos or LDAP support )
IAS for Windows 2000 & 2003 server.

IAS:
Standard edition : only 50 NAS ( i.e 50 routers )
Enterprise Edition ( no limit of devices )

From my point of view, if you want to manage 1000 devices, Cisco ACS
is the easiest choice.

Regards.

His concern is the loss of CLI command authorization and accounting.
