How to store multiple passwords inside a VAULT ?

Issue

• Can we store more than one credential inside a single Vault?

• While adding vault for storing second password, giving below exceptions:

/host=the_host/core-service=vault:add(vault-options=[("KEYSTORE_URL" => "/abc/jboss-eap-7.3/vault/vault.keystore"),("KEYSTORE_PASSWORD" => "MASK-********"),("KEYSTORE_ALIAS" => "vault"),("SALT" => "1234abcd"),("ITERATION_COUNT" => "120"),("ENC_FILE_DIR" => "/abc/jboss-eap-7.3/vault/")])

"outcome" => "failed",
    "result" => {},
    "failure-description" => {"host-failure-descriptions" => {"Server-1" => "WFLYCTL0212: Duplicate resource [
    (\"host\" => \"Server-1\"),
    (\"core-service\" => \"vault\")
]"}},
    "rolled-back" => true
}
