Overview

Package auth is not for public use.

The API for packages in the 'private' directory have no stability guarantee.

The packages within the 'private' directory would normally be put into an 'internal' directory to prohibit their use outside the 'mongo' directory. However, some MongoDB tools require very low-level access to the building blocks of a driver, so we have placed them under 'private' to allow these packages to be imported by projects that need them.

These package APIs may be modified in backwards-incompatible ways at any time.

You are strongly discouraged from directly using any packages under 'private'.

type DefaultAuthenticator struct {
	Cred *Cred
	// contains filtered or unexported fields
}

DefaultAuthenticator uses SCRAM-SHA-1 or MONGODB-CR depending on the server version.

func (*DefaultAuthenticator) Auth

Auth authenticates the connection.

func (*DefaultAuthenticator) CreateSpeculativeConversation

func (a *DefaultAuthenticator) CreateSpeculativeConversation() (SpeculativeConversation, error)

CreateSpeculativeConversation creates a speculative conversation for SCRAM authentication.

type Error

type Error struct {
	// contains filtered or unexported fields
}

Error is an error that occurred during authentication.

func (*Error) Error

func (e *Error) Error() string

func (*Error) Inner

func (e *Error) Inner() error

Inner returns the wrapped error.

func (*Error) Message

func (e *Error) Message() string

Message returns the message.

func (*Error) Unwrap

func (e *Error) Unwrap() error

Unwrap returns the underlying error.

type ExtraOptionsSaslClient

type ExtraOptionsSaslClient interface {
	StartCommandOptions() bsoncore.Document
}

ExtraOptionsSaslClient is a SaslClient that appends options to the saslStart command.

type HandshakeOptions

type HandshakeOptions struct {
	AppName               string
	Authenticator         Authenticator
	Compressors           []string
	DBUser                string
	PerformAuthentication func(description.Server) bool
	ClusterClock          *session.ClusterClock
	ServerAPI             *driver.ServerAPIOptions
	LoadBalanced          bool
	HTTPClient            *http.Client
}

HandshakeOptions packages options that can be passed to the Handshaker() function. DBUser is optional but must be of the form <dbname.username>; if non-empty, then the connection will do SASL mechanism negotiation.

type MongoDBAWSAuthenticator

type MongoDBAWSAuthenticator struct {
	// contains filtered or unexported fields
}

MongoDBAWSAuthenticator uses AWS-IAM credentials over SASL to authenticate a connection.

func (*MongoDBAWSAuthenticator) Auth

func (*MongoDBCRAuthenticator) Auth

func (a *MongoDBCRAuthenticator) Auth(ctx context.Context, cfg *Config) error

Auth authenticates the connection.

The MONGODB-CR authentication mechanism is deprecated in MongoDB 3.6 and removed in MongoDB 4.0.

type MongoDBX509Authenticator

}

SaslClientCloser is a SaslClient that has resources to clean up.

type ScramAuthenticator

type ScramAuthenticator struct {
