![]() This object holds the details required to establish connections with a Neo4j database, including server URIs, credentials and other configuration. Parameters ( Any) – extra key word parameters passed along to theĮvery Neo4j-backed application will require a driver object. Scheme ( str | None) – specifies the type of authentication Principal ( str | None) – specifies who is being authenticatedĬredentials ( str | None) – authenticates the principal custom_auth ( principal, credentials, realm, scheme, ** parameters ) ¶ Parameters :īase64_encoded_token ( str) – a base64 encoded authentication token generatedĪuth neo4j. This will set the scheme to “bearer” for the auth token. Generate an auth token for Single-Sign-On providers. Parameters :īase64_encoded_ticket ( str) – a base64 encoded service ticket, this will setĪuth neo4j. This will set the scheme to “kerberos” for the auth token. Generate a kerberos auth token with the base64 encoded ticket. ![]() kerberos_auth ( base64_encoded_ticket ) ¶ Realm ( str | None) – specifies the authentication providerĪuth token for use with GraphDatabase.driver() orĪsyncGraphDatabase.driver() Return type :Īuth neo4j. Password ( str) – current password, this will set the credentials User ( str) – user name, this will set the This will set the scheme to “basic” for the auth token. Generate a basic auth token for a given user and password. basic_auth ( user, password, realm = None ) ¶ Auth Token Helper Functions ¶Īlternatively, one of the auth token helper functions can be used. It might be changed without following the deprecation policy. If None, the authentication information is considered to notĮxpire until the server explicitly indicates so. Indicating when the authentication information expires. Parameters :Īuth ( Tuple | Auth | None) – The authentication information.Įxpires_at ( float | None) – Unix timestamp (seconds since 00:00:00 UTC) This class is used with AuthManagers.expiration_based() andĪsyncAuthManagers.expiration_based(). Represents potentially expiring authentication information. ExpiringAuth ( auth, expires_at = None ) ¶ Reached its expiry time or because the server flagged it asĪuthManager class th_management.
