RadiusNT includes a migration option to auth the first time from the NT SAM
then replace the user's password in the database (so that all other times
don't need
the NT SAM account). That is the only migration option that I know of that
fairly seemless.

No. Most are fairly custom, depending on what you want to do. Emerald will
export a Livingston/Ascend compatable users file. There is also a
program called radusers that does that as well. We are working on a
method for syncing the passwd/shadow file, but it will require the OpenLink
ODBC drivers for unix.

Not really. You will loose some functionality of Emerald if you use
another RADIUS server that is not integrated into Emerald.

Something like a single/dual PII-300+ with 256mb of RAM and Ultrawide
SCSI should be fine. Disk and memory are the two key components.

There isn't a cookie cutter type solution for it yet. We are working on
solutions, but don't have any generically available. You might want to
runn accounting to a pair of RadiusNT boxes, even if they don't have
authentication. It makes things a lot eaier.

You really can't. RadiusNT supports the migration option if its the
authenticating server, though.

There are some example ASP and Cold Fusion scripts on our FTP site.
