orderattribute for the realm.
See Native realm settingsedit for all of the options you can set for the
nativerealm. For example, the following snippet shows a
nativerealm configuration that sets the
orderto zero so the realm is checked first:
xpack: security: authc: realms: native: native1: order: 0
To limit exposure to credential theft and mitigate credential compromise, the native realm stores passwords and caches user credentials according to security best practices. By default, a hashed version of user credentials is stored in memory, using a salted
sha-256hash algorithm and a hashed version of passwords is stored on disk salted and hashed with the
bcrypthash algorithm. To use different hash algorithms, see User cache and password hash algorithmsedit.
