Basic authentication is a simple protocol that uses the HTTP headers and the browser to authenticate users. User credentials are sent to the server in the header Authorization with user:password base64 encoded:
Authorization: Basic dXNlcjpwYXNzd29yZA==
It is secure as long as the communication to the server is encrypted (with SSL for example).
On the server side, you have to provide a user store for Datashare. For now we are using a Redis data store.
So you have to provision users. The passwords are sha256 hex encoded. For example using bash:
$ echo -n bar | sha256sum
fcde2b2edba56bf408601fb721fe9b5c338d10ee429ea04fae5511b68fbf8fb9 -
Then insert the user like this in Redis:
$ redis-cli -h my.redis-server.org
redis-server.org:6379> set foo '{"uid":"foo", "password":"fcde2b2edba56bf408601fb721fe9b5c338d10ee429ea04fae5511b68fbf8fb9", "groups_by_applications":{"datashare":["local-datashare"]}}'
If you use other indices, you'll have to include them in the group_by_applications, but local-datashare should remain. For exammple if you use myindex:
$ redis-cli -h my.redis-server.org
redis-server.org:6379> set foo '{"uid":"foo", "password":"fcde2b2edba56bf408601fb721fe9b5c338d10ee429ea04fae5511b68fbf8fb9", "groups_by_applications":{"datashare":["myindex","local-datashare"]}}'
Then you should see this popup:

Here is an example of launching Datashare with Docker and the basic auth provider filter backed in Redis:
