Azure Blob Storage - Retrieve user that reads or writes blob in Storage Container

Question

I have a question regarding Blob Storage: how to know the AD user that writes or reads a blob file in a container. I cannot see the property at blob level, neither in Storage Account Activity Log (at least for a specific blob file).

Is there a way to know, for each blob in my container, which user has accessed it and how it dealt with the blob?

Many thanks for your help

Unfortunately it's not an option in the current logs that are generated, they aren't fine grained yet(will be better on a newer release). the current log format would only indicate whether the request was authenticated or not,

This is an example of logs 2.0 for azure storage:

1.0;2014-06-19T01:33:54.0926521Z;PutBlob;Success;201;197;54;authenticated;storagesample;storagesample;blob;"https://storagesample.blob.core.windows.net/sample-container1/00001.txt";"/storagesample/sample-container1/00001.txt";a200be85-1c98-4dd9-918e-f13d8c0538e0;0;192.100.0.102:4362;2014-02-14;460;23;225;0;23;"DrPO6z1f00SCsomhaf+J/A==";"DrPO6z1f00SCsomhaf+J/A==";""0x8D15975AA456EA4"";Thursday, 19-Jun-14 01:33:53 GMT;;"WA-Storage/4.0.1 (.NET CLR 4.0.30319.34014; Win32NT 6.3.9600.0)";;"1fe6814a-e4cb-4195-a3cf-837dc7120f68"

It only shows whether it's an authenticated request or not, but not specifically which User accessed which blob.The full format of logs can be viewed here
