I ran across this today. I am using AF SDK 2.8 against PI Server 2010 R2 (3.4.385.77). I have the PI Buffering Service running under a mapping for the server and the mapping has read/write premissions to the PI tag. The user running my custom app has only read premissions to the tag. When the user goes to edit the vaule of the tag, they are allowed even thought they shouldn't have premission. Am I going crazy, or does this sound wrong?
I've been on the telephone with OSIsoft for last 2 hours and I'm not sure if we have resolved anything or not so I am reaching out here for some help. I did get this known issue number, 22387OSI8, but not viable solution. Can someone else confirm this behaviour for me?
