Folks,

I am investigating the possibility of having each CIFS filesystem be part of a different AD domain.

I believe OpenSolaris box can be part of only one AD at a time.

Correct.

I am an OpenSolaris newbie. As I understand, the service responsible for ensuring AD connectivity is smb. The FMRI is svc:/network/smb/server:default. I am wondering if it is possible to run multiple instances of smb service and configure each service with different parameters?

Alas, it's more complicated than that; there's some global state and I suspect (though I'm not an expert) that the kernel components of the service aren't prepared to interact with more than one instance of the userland components.

If this is not possible, can zoning help? As I understand, a zone provides a virtual operating system abstraction to run an application? Is it not possible to create multiple zones and sandbox smb service within each zone?

Zones come closer, but I believe that at the moment you can't run SMB in a zone.

Note that another way to achieve similar results is to have your AD domains trust each other. The easiest way to do that is to have them all be part of the same forest, though you can also do it with explicit trust relationships. When you do that, the OpenSolaris system will let users from anywhere in the trust network connect.
