Just curious what my options are?

We have an FTP server running OES on SLES 9. It works okay with LUM.

I now need to add another FTP server with Solaris in China and integrate
it with eDirectory.

We own IDM and have already upgraded to version 3. Is the Linux/Unix
driver free or an additional cost? What I'd like to have (instead of
using LUM) is to create a user in eDirectory and have it create it
locally on the Solaris box and then just keep user data synched with
eDirectory.

What kind of option do I have to make this happen?

Thanks,
Joe
