Get a Single Database User¶

Note

Groups and projects are synonymous terms. Your {GROUP-ID} is the same as your project ID. For existing groups, your group/project ID remains the same. The resource and corresponding endpoints use the term groups.

https://cloud.mongodb.com/api/atlas/v1.0

The Atlas API authenticates using HTTP Digest Authentication. Provide a programmatic API public key and corresponding private key as the username and password when constructing the HTTP request.

To learn how to configure API access for an Atlas project, see Configure Atlas API Access.

Syntax¶

GET /groups/{GROUP-ID}/databaseUsers/{databaseName}/{USERNAME}

Request Path Parameters¶

Parameter	Required/Optional	Description
`GROUP-ID`	Required.	Unique identifier for the project.
`databaseName`	Required.	The user's authentication database. Accepted values include: `$external` if the user is authenticated using X.509 certificates, LDAP, or AWS IAM. `admin` users authenticated using SCRAM-SHA. This is the default authentication scheme in Atlas.
`USERNAME`	Required.	Username to retrieve. Must be a fully qualified distinguished name, as defined in RFC-2253, if: `ldapAuthType` is `USER` or `GROUP`, or `x509Type` is `CUSTOMER`. Must be an ARN if `awsIAMType` is `USER`.

Request Query Parameters¶

This endpoint might use any of the HTTP request query parameters available to all Atlas API resources. All of these are optional.

Name

Type

Necessity

Description

Default

pretty

boolean

Optional

Flag indicating whether the response body should be in a prettyprint format.

false

envelope

boolean

Optional

Flag indicating if Atlas should wrap the response in a JSON envelope.

This option may be needed for some API clients. These clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query.

For endpoints that return one result, the response body includes:


status	HTTP response code
envelope	Expected response body

false

Request Body Parameters¶

This endpoint does not use HTTP request body parameters.

Response Elements¶

If you set the query element envelope to true, the response is wrapped by the content object.

Response Element

Type

Description

databaseName

string

The user's authentication database. A user must provide both a username and authentication database to log into MongoDB.

Returned values include:

$external if the user is authenticated using X.509 certificates, LDAP, or AWS IAM.
admin users authenticated using SCRAM-SHA.
This is the default authentication scheme in Atlas.

deleteAfterDate

string

Timestamp in ISO 8601 date and time format in UTC after which Atlas deletes the user. This field is only present if an expiration date was specified when creating the entry.

groupId

string

Unique identifier of the Atlas project to which the user belongs.

labels

array of documents

Array containing key-value pairs that tag and categorize the database user.

ldapAuthType

string

Method by which the specified username is authenticated. If no value is given, Atlas uses the default value of NONE.

Returned values include:


`NONE`	Atlas authenticates this user through SCRAM-SHA, not LDAP.
`USER`	LDAP server authenticates this user through the user's LDAP user.
`GROUP`	LDAP server authenticates this user using their LDAP user and authorizes this user using their LDAP group. To learn more about LDAP security, see Set up User Authentication and Authorization with LDAP.

x509Type

string

X.509 method by which the provided username is authenticated. If no value is given, Atlas uses the default value of NONE.

The possible types are:


`NONE`	The user does not use X.509 authentication.
`MANAGED`	The user is being created for use with Atlas-managed X.509. Externally authenticated users can only be created on the `$external` database.
`CUSTOMER`	The user is being created for use with Self-Managed X.509. Users created with this `x509Type` require a Common Name (CN) in the `username` field. To learn more, see RFC 2253. Externally authenticated users can only be created on the `$external` database.

awsIAMType

string

If this value is set, the new database user authenticates with AWS IAM credentials.

Possible response values are:


`NONE`	The user does not use AWS IAM credentials.
`USER`	New database user has AWS IAM user credentials.
`ROLE`	New database user has credentials associated with an AWS IAM role.

links

document array

One or more links to sub-resources and/or related resources.

roles

string array

Array of this user's roles and the databases / collections on which the roles apply. A role allows the user to perform particular actions on the specified database. A role on the admin database can include privileges that apply to the other databases as well.

roles

.collectionName

string

Collection on which the user has the specified role.

roles

.databaseName

string

Database on which the user has the specified role. A role on the admin database can include privileges that apply to the other databases.

roles

.roleName

string

Name of the role. The accepted values are:

atlasAdmin
readWriteAnyDatabase
readAnyDatabase
backup
clusterMonitor
dbAdmin
dbAdminAnyDatabase
enableSharding
This role is specific to MongoDB databases managed by Atlas. The role allows the user to enable sharding on a database and to shard a collection.
read
readWrite
A name of a custom role

scopes

array of documents

Array of clusters and Atlas Data Lakes that this user has access to. Returns an empty array if the user has access to all the clusters and Atlas Data Lakes in the project. Database users are granted access to all resources by default.

scopes.name

string

Name of the cluster or Atlas Data Lake that this user has access to.

scopes.type

string

Type of resource that this user has access to. Valid values are:

CLUSTER
DATA_LAKE

username

string

Username for authenticating to MongoDB.

A fully qualified distinguished name, as defined in RFC-2253, is returned if:

ldapAuthType is USER or GROUP, or
x509Type is CUSTOMER.

An ARN is returned if:

awsIAMType is USER or ROLE.

Examples¶

Request¶

Retrieve one database user that Atlas authenticates using SCRAM-SHA and the admin database.
