Idea #21595

Updated by Peter Amstutz about 2 months ago

The 'shared' directory uses full names.    These have a couple of problems: 

 * Always contain spaces and may have other characters that make it awkward with Unix tooling 
 * Not guaranteed to be unique.    For example pirca Pirca has multiple accounts with full_name "Peter Amstutz".    FUSE ends up picking one account and the other accounts just can't be accessed through FUSE. others are unavailable. 

 It should use 'username' instead, which is unique on a given Arvados instance. instead. 

 I think the only question is whether it is worth the effort to maintain backwards compatibility (by making the 'username' behavior a new option) or we just change the existing behavior in place. 

 I suppose one way to do it would be to change to using usernames by default but add an option that restores the previous behavior of using full names.
