I have verified the password of user elastic.
```auto
curl -k -u elastic 'https://localhost:9200/_xpack/security/_authenticate?pretty'
Enter host password for user 'elastic':
{
"username" : "elastic",
"roles" : [
"superuser"
],
"full_name" : null,
"email" : null,
"metadata" : {
"_reserved" : true
},
"enabled" : true,
"authentication_realm" : {
"name" : "reserved",
"type" : "reserved"
},
"lookup_realm" : {
"name" : "reserved",
"type" : "reserved"
},
"authentication_type" : "realm"
}
```
But after I restart Elasticsearch service, the log file has error:
```auto
failed to retrieve password hash for reserved user [elastic]
org.elasticsearch.action.UnavailableShardsException: at least one primary shard for the index [.security-7] is unavailable
Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic]
```
How do I need to check the configuration? Thanks
