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.

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

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

For complete documentation on configuring API access for an Atlas project, see Configure Atlas API Access.

Syntax

copy

GET /api/atlas/v1.0/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

The following query parameters are optional:

Query Parameter	Type	Description	Default
pretty	boolean	Displays response in a prettyprint format.	false
envelope	boolean	Specifies whether or not to wrap the response in an envelope.	false

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
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.
