Hey guys,
I am playing with user/role management API in Shield 2.3 (thanks for getting this out!).
I observed that I can specify users in the run\_as\_role list using wildcards! This is super useful to me. However, this feature is not documented here: [https://www.elastic.co/guide/en/shield/current/submitting-requests-for-other-users.html](https://www.elastic.co/guide/en/shield/current/submitting-requests-for-other-users.html).
Just wanted to make sure the configuration works as intended and this is merely a documentation issue 😉
Thx!

The wildcard usage is definitely intended and I agree that we can improve the documentation here so I will open up a issue to get some more detail added. Also, if it helps, not only are wildcards supported but you can also use the special [regular expression syntax](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-regexp-query.html#regexp-syntax). Note: you'll need to[wrap the expression in `/` characters](https://www.elastic.co/guide/en/shield/current/defining-roles.html) at the beginning and end.
