class pysap.SAPHDB.SAPHDBAuthGSSMethod(username, krb5ticket=None, krb5ticket_callback=None, krb5oid=None, typeoid=None)

Bases: pysap.SAPHDB.SAPHDBAuthMethod

SAP HDB Authentication using GSS.

KRB5OID_KERBEROS5 = '1.2.840.113554.1.2.2'

METHOD = 'GSS'

TYPEOID_GSS_KRB5_NT_PRINCIPAL_NAME = '1.2.840.113554.1.2.2.1'

TYPEOID_GSS_KRB5_NT_PRINCIPAL_NAME_pre_RFC_1964 = '1.2.840.113554.1.2.2.2'

authenticate(connection)

Method to authenticate the client connection. It performs the round trip with the server as required by the method implemented, and returns the AUTHENTICATION Part.

Parameters:connection (SAPHDBConnection) – connection to the server Returns:authentication part to use in Connect packet Return type:SAPHDBPart Raise:SAPHDBAuthenticationError

craft_authentication_request(value=None, connection=None)

The authentication requests contains an empty username, the method, and a GSS token.

In most of the cases this GSS token is a SPNego structure, although the HANA implementation doesn’t use the standard ASN.1 encoding and instead leverage the same Authentication Field format.

craft_authentication_response_part(auth_response_part, value=None)

In GSS, the final round trip with the server returns a GSS token that is mech specific.

In the case of Kerberos, the reply to the final roundtrip before the CONNECT contains an GSSAPI KRB5 AP-REP structure. At this stage we’re not parsing nor validating it.

The part to include in the CONNECT message is just a confirmation of the authentication handled. Note that this CONNECT packet has the username specified as in all other auth mechanisms.

process_connect_response(connect_reponse, connection=None)

Process the final response from the authentication process when needed, according to the authentication method.

• value (string) – value to include in the authentication response

Returns:

the authentication response part

Return type:

SAPHDBPart

process_connect_response(connect_reponse, connection=None)

Process the final response from the authentication process when needed, according to the authentication method.

class pysap.SAPHDB.SAPHDBAuthSAMLMethod(username, saml_assertion)

Bases: pysap.SAPHDB.SAPHDBAuthMethod

SAP HDB Authentication using Security Assertion Markup Language (SAML) 2.0 Bearer Assertions.

METHOD = 'SAML'

craft_authentication_request(value=None, connection=None)

The initial authentication request should be performed as usual in other methods, with an empty username and the entire SAML Assertion or SAML Response as the value.

craft_authentication_response_part(auth_response_part, value=None)

In SAML, the first round trip with the server returns the SAML username to use when authentication, so we must set it at this point.

Sends a packet to the server

sr(message)

Sends a packet to the server and receives a response.

SAP HDB Connection using TLS

This class wraps the connection socket with a TLS-enabled one for use as a secure channel. We’re using TLS 1.2 by default but setting RSA-based cipher suites without (EC)DHE so traffic can be easily decrypted in Wireshark.

connect()

Creates a SAPNIStreamSocket connection to the host/port. If a route was specified, connect to the target HANA server through the SAP Router.
