I can summarize the issue with the following picture:
For The Same Database "CL" when I login using OS authentication I cannot view the data, while if I login using the DB authentication I can view it !.
Everything was working fine before upgrading form 10.5.0 to 10.6.0. I used another machine that runs 10.5.0 with the same login info and it worked fine just to eliminate any permissions or privileges change issue.
I assumed that the issue from my machine so I went further and a upgraded a new machine but unfortunately I had the same issue !.
The same issue happen with me with I upgraded form 10.5.0 to 10.5.1 and here is the link for the post
