ArangoDB v3.4 reached End of Life (EOL) and is no longer supported.

This documentation is outdated. Please see the most recent version here: Latest Docs

Managing Users in the ArangoDB Shell

Please note, that for backward compatibility the server access levels follow from the database access level on the database _system.

Also note that the server and database access levels are represented as

  • rw: for Administrate
  • ro: for Access
  • none: for No access

This is again for backward compatibility.

Example

Fire up arangosh and require the users module. Use it to create a new user:

arangosh> const users = require('@arangodb/users');
arangosh> users.save('JohnSmith', 'mypassword');

Creates a user called JohnSmith. This user will have no access at all.

arangosh> users.grantDatabase('JohnSmith', 'testdb', 'rw');

This grants the user Administrate access to the database testdb. revokeDatabase will revoke this access level setting.

Note: Be aware that from 3.2 onwards the grantDatabase will not automatically grant users the access level to write or read collections in a database. If you grant access to a database testdb you will additionally need to explicitly grant access levels to individual collections via grantCollection.

The upgrade procedure from 3.1 to 3.2 sets the wildcard database access level for all users to Administrate and sets the wildcard collection access level for all user/database pairs to Read/Write.

arangosh> users.grantCollection('JohnSmith', 'testdb', 'testcoll', 'rw');

Save

users.save(user, passwd, active, extra)

This will create a new ArangoDB user. The user name must be specified in user and must not be empty.

The password must be given as a string, too, but can be left empty if required. If you pass the special value ARANGODB_DEFAULT_ROOT_PASSWORD, the password will be set the value stored in the environment variable ARANGODB_DEFAULT_ROOT_PASSWORD. This can be used to pass an instance variable into ArangoDB. For example, the instance identifier from Amazon.

If the active attribute is not specified, it defaults to true. The extra attribute can be used to save custom data with the user.

This method will fail if either the user name or the passwords are not specified or given in a wrong format, or there already exists a user with the specified name.

Note: The user will not have permission to access any database. You need to grant the access rights for one or more databases using grantDatabase.

Examples

arangosh> require('@arangodb/users').save('my-user', 'my-secret-password');

{ 
  "user" : "my-user", 
  "active" : true, 
  "extra" : { 
  }, 
  "code" : 201 
}

Grant Database

users.grantDatabase(user, database, type)

This grants type (‘rw’, ‘ro’ or ‘none’) access to the database for the user. If database is "*", this sets the wildcard database access level for the user user.

The server access level follows from the access level for the database _system.

Revoke Database

users.revokeDatabase(user, database)

This clears the access level setting to the database for the user and the wildcard database access setting for this user kicks in. In case no wildcard access was defined the default is No Access. This will also clear the access levels for all the collections in this database.

Grant Collection

users.grantCollection(user, database, collection, type)

This grants type (‘rw’, ‘ro’ or ‘none’) access level to the collection in database for the user. If collection is "*" this sets the wildcard collection access level for the user user in database database.

Revoke Collection

users.revokeCollection(user, database)

This clears the access level setting to the collection collection for the user user. The system will either fallback to the wildcard collection access level or default to No Access

Replace

users.replace(user, passwd, active, extra)

This will look up an existing ArangoDB user and replace its user data.

The username must be specified in user, and a user with the specified name must already exist in the database.

The password must be given as a string, too, but can be left empty if required.

If the active attribute is not specified, it defaults to true. The extra attribute can be used to save custom data with the user.

This method will fail if either the user name or the passwords are not specified or given in a wrong format, or if the specified user cannot be found in the database.

Note: this function will not work from within the web interface

Examples

arangosh> require("@arangodb/users").replace("my-user", "my-changed-password");

{ 
  "user" : "my-user", 
  "active" : true, 
  "extra" : { 
  }, 
  "code" : 200 
}

Update

users.update(user, passwd, active, extra)

This will update an existing ArangoDB user with a new password and other data.

The user name must be specified in user and the user must already exist in the database.

The password must be given as a string, too, but can be left empty if required.

If the active attribute is not specified, the current value saved for the user will not be changed. The same is true for the extra attribute.

This method will fail if either the user name or the passwords are not specified or given in a wrong format, or if the specified user cannot be found in the database.

Examples

arangosh> require("@arangodb/users").update("my-user", "my-secret-password");

{ 
  "user" : "my-user", 
  "active" : true, 
  "extra" : { 
  }, 
  "code" : 200 
}

isValid

users.isValid(user, password)

Checks whether the given combination of user name and password is valid. The function will return a boolean value if the combination of user name and password is valid.

Each call to this function is penalized by the server sleeping a random amount of time.

Examples

arangosh> require("@arangodb/users").isValid("my-user", "my-secret-password");

true

Remove

users.remove(user)

Removes an existing ArangoDB user from the database.

The user name must be specified in User and the specified user must exist in the database.

This method will fail if the user cannot be found in the database.

Examples

arangosh> require("@arangodb/users").remove("my-user");

Document

users.document(user)

Fetches an existing ArangoDB user from the database.

The user name must be specified in user.

This method will fail if the user cannot be found in the database.

Examples

arangosh> require("@arangodb/users").document("my-user");
Show execution results
Hide execution results
{ 
  "user" : "my-user", 
  "active" : true, 
  "extra" : { 
  }, 
  "code" : 200 
}

All

users.all()

Fetches all existing ArangoDB users from the database.

Examples

arangosh> require("@arangodb/users").all();
Show execution results
Hide execution results
[ 
  { 
    "user" : "tester", 
    "active" : false, 
    "extra" : { 
    } 
  }, 
  { 
    "user" : "admin", 
    "active" : true, 
    "extra" : { 
    } 
  }, 
  { 
    "user" : "root", 
    "active" : true, 
    "extra" : { 
    } 
  }, 
  { 
    "user" : "my-user", 
    "active" : true, 
    "extra" : { 
    } 
  } 
]

Reload

users.reload()

Reloads the user authentication data on the server

All user authentication data is loaded by the server once on startup only and is cached after that. When users get added or deleted, a cache flush is done automatically, and this can be performed by a call to this method.

Examples

arangosh> require("@arangodb/users").reload();

Permission

users.permission(user, database[, collection])

Fetches the access level to the database or a collection.

The user and database name must be specified, optionally you can specify the collection name.

This method will fail if the user cannot be found in the database.

Examples

arangosh> require("@arangodb/users").permission("my-user", "testdb");
