Please consider a scenario shown on the image below.
The customer has 2 separate network segments.
Alpha A - local net and Sigma Σ - internet segment - kind of a DMZ.
All of the users in the A have their corresponding accounts in the Σ. Every one of them has 2 physical machines. The 1st attached to A and the 2nd to Σ.
The only 2 possible options to transfer the data between the segments are
1) file share
The aim of the customer is to implement a PrintRelease solution that will allow to put all printers\MFDs into the A segment (print load from the Σ segment is to be somehow transferred into the A and released there)
The questions are:
How to architect such a system? Note, our competitors seemed to find a way (attachment), although there are no details in there, just a high-level implementation.
Email way, though may push the customer to buy MobileLicense and at the same time simplify the design, is unlikely due to several obstacles:
2.1 not all file formats are supported.
2.2 the customer does not allow IMAP protocol on its Exchange server in the A domain.
2.3 SAMAccountName are most certainly different for a user in those two segments.
