Small Bug Fix on Listing SMB Shares with Kerberos Auth

This is a bug I came across while working with Kerberos on another project.  If the information of the user in the ticket is not in the database, it gives an index error cause of user_id is empty. I thought about adding the ticket information as user_id, but since it wouldn't have any meaning when it expired, I proceeded with pass.
