How to list all existing users using Riak admin-shell?

In Riak, how do I retrieve a list of currently existing users? I can't seem to find it anywhere on Stack Overflow.

This info can be accessed at any time:

riak-admin security print-users

Example output, assuming user named riakuser with an assigned password:

+----------+--------+----------------------+------------------------------+
| username | groups |       password       |           options            |
+----------+--------+----------------------+------------------------------+
| riakuser |        |983e8ae1421574b8733824|              []              |
+----------+--------+----------------------+------------------------------+

Note: All passwords are displayed in encrypted form in console output.

If you’d like to see which permissions have been assigned to riakuser, you would need to use the print-grants command.

The security print-user (singular) command can be used with a name as argument to see the same information as above, except for only that user.

See basho/docs Security Basics for more information on user management.
