We have implemented Storage Extension in Tridion Deployer to push the content to a thrid-party storage. This third-party storage has got a requirement to capture the name of the user who publishes/unpublishes the content.
Our Tridion Template adds the user info to the published content. As Template gets executed while publishing and published content itself includes the user info, third-party storage gets the info needed. However no Template is executed while unpublishing. If I check the transport package created while unpublishing, it doesn't have any information about the user who unpublished.
How can I get "user who unpublished" in Storage Extension?
