I can't see how the above map entry can provide these mappings and if
you can't provide an accurate description of how the mounts are
constructed I can't tell you whether Linux autofs can, either do what

No, I don't understand at all, but that's because you've not provided
any useful information.

Where in the Solaris documentation is the behavior of this type of map
entry described.
