The other day someone asked why LOGbinder for SharePoint puts the characters ” i:0#.w| ” in front of the usernames. For example, instead of LB\capt.kirk ” as the username, it would show i:0#.w|LB\capt.kirk ”.

LOGbinder does not do this; it actually comes from SharePoint. This is how SharePoint 2010 and SharePoint 2013 encodes identity claims. It's SharePoint's way of representing the authentication method used in SharePoint. Here is an article on what it means: SharePoint 2010/2013: Claims Encoding

Starting from version 6, LOGbinder now has the option to remove (trim) claims encoding from the user names.
