Name of the Python LDAP module to use. Only ``'ldap'`` is supported at the moment. * ``'url'`` Optional; defaults to ``'ldapi:///'``. URL to the LDAP server. * ``'bind'`` Optional; defaults to ``None``. Describes how to bind an identity to the LDAP connection. If ``None``, an anonymous connection is made. Valid keys: * ``'method'`` Optional; defaults to ``None``. The authentication method to use. Valid values include but are not necessarily limited to ``'simple'``, ``'sasl'``, and ``None``. If ``None``, an anonymous connection is made. Available methods depend on the chosen backend. * ``'mechanism'`` Optional; defaults to ``'EXTERNAL'``. The SASL mechanism to use. Ignored unless the method is ``'sasl'``. Available methods depend on the chosen backend and the server's capabilities. * ``'credentials'`` Optional; defaults to ``None``. An object specific to the chosen SASL mechanism and backend that represents the authentication credentials. Ignored unless the method is ``'sasl'``. For the ``'ldap'`` backend, this is a dictionary. If ``None``, an empty dict is used. Keys: * ``'args'`` Optional; defaults to an empty list. A list of arguments to pass to the SASL mechanism constructor. See the SASL mechanism constructor documentation in the ``ldap.sasl`` Python module. * ``'kwargs'`` Optional; defaults to an empty dict. A dict of keyword arguments to pass to the SASL mechanism constructor. See the SASL mechanism constructor documentation in the ``ldap.sasl`` Python module. * ``'dn'`` Optional; defaults to an empty string. The distinguished name to bind. * ``'password'`` Optional; defaults to an empty string. Password for binding. Ignored if the method is ``'sasl'``. * ``'tls'`` Optional; defaults to ``None``. A backend-specific object containing settings to override default TLS behavior. For the ``'ldap'`` backend, this is a dictionary. Not all settings in this dictionary are supported by all versions of ``python-ldap`` or the underlying TLS library. If ``None``, an empty dict is used. Possible keys: * ``'starttls'`` If present, initiate a TLS connection using StartTLS. (The value associated with this key is ignored.) * ``'cacertdir'`` Set the path of the directory containing CA certificates. * ``'cacertfile'`` Set the pathname of the CA certificate file. * ``'certfile'`` Set the pathname of the certificate file. * ``'cipher_suite'`` Set the allowed cipher suite. * ``'crlcheck'`` Set the CRL evaluation strategy. Valid values are ``'none'``, ``'peer'``, and ``'all'``. * ``'crlfile'`` Set the pathname of the CRL file. * ``'dhfile'`` Set the pathname of the file containing the parameters for Diffie-Hellman ephemeral key exchange. * ``'keyfile'`` Set the pathname of the certificate key file. * ``'newctx'`` If present, instruct the underlying TLS library to create a new TLS context. (The value associated with this key is ignored.) * ``'protocol_min'`` Set the minimum protocol version. * ``'random_file'`` Set the pathname of the random file when ``/dev/random`` and ``/dev/urandom`` are not available. * ``'require_cert'`` Set the certificate validation policy. Valid values are ``'never'``, ``'hard'``, ``'demand'``, ``'allow'``, and ``'try'``. * ``'opts'`` Optional; defaults to ``None``. A backend-specific object containing options for the backend. For the ``'ldap'`` backend, this is a dictionary of OpenLDAP options to set. If ``None``, an empty dict is used. Each key is a the name of an OpenLDAP option constant without the ``'LDAP_OPT_'`` prefix, then converted to lower case. :returns: an object representing an LDAP connection that can be used as the ``connect_spec`` argument to any of the functions in this module (to avoid the overhead of making and terminating multiple connections). This object should be used as a context manager. It is safe to nest ``with`` statements. CLI Example: .. code-block:: bash salt '*' ldap3.connect "{ 'url': 'ldaps://ldap.example.com/', 'bind': { 'method': 'simple', 'dn': 'cn=admin,dc=example,dc=com', 'password': 'secret'} }" NZbackendr z-unsupported backend or required Python modulez unavailable: �urlz ldapi:///�tls)�starttls�newctxT)ZcrlcheckZ require_certZ OPT_X_TLS_r2 Fr3 r �optsZOPT_r$ )� isinstancer* r r r" r Z initializeZVERSION3Zprotocol_version�itemsZ set_optionr �upperZ start_tls_sZOPT_X_TLS_NEWCTXZ OPT_REFERRALSr% r r ) � connect_specZ backend_namer0 r# r1 �vars�k�vr4 �optr r r r �connectl s^ �� � ���r= �subtree�(objectClass=*)c C s� t | �}ttd|�� �}z|j�|||||�}W t |�S tjy+ g }Y t |�S tjyD } z t|� W Y d}~t |�S d}~ww )a� Search an LDAP database. :param connect_spec: See the documentation for the ``connect_spec`` parameter for :py:func:`connect`. :param base: Distinguished name of the entry at which to start the search. :param scope: One of the following: * ``'subtree'`` Search the base and all of its descendants. * ``'base'`` Search only the base itself. * ``'onelevel'`` Search only the base's immediate children. :param filterstr: String representation of the filter to apply in the search. :param attrlist: Limit the returned attributes to those in the specified list. If ``None``, all attributes of each entry are returned. :param attrsonly: If non-zero, don't return any attribute values. :returns: a dict of results. The dict is empty if there are no results. The dict maps each returned entry's distinguished name to a dict that maps each of the matching attribute names to a list of its values. CLI Example: .. code-block:: bash salt '*' ldap3.search "{ 'url': 'ldaps://ldap.example.com/', 'bind': { 'method': 'simple', 'dn': 'cn=admin,dc=example,dc=com', 'password': 'secret', }, }" "base='dc=example,dc=com'" ZSCOPE_N) r= r r r7 r+ Zsearch_sZNO_SUCH_OBJECTr r �dict) r8 �baseZscopeZ filterstrZattrlistZ attrsonlyr# �resultsr r r r �search8 s :����rC c C s� t | �}dd� |�� D �}t�dt|�t|�� d|v r'dd� |d D �|d< tj�|�}z |j� ||� W dS tj yO } z t |� W Y d}~dS d}~ww ) a� Add an entry to an LDAP database. :param connect_spec: See the documentation for the ``connect_spec`` parameter for :py:func:`connect`. :param dn: Distinguished name of the entry. :param attributes: Non-empty dict mapping each of the new entry's attributes to a non-empty iterable of values. :returns: ``True`` if successful, raises an exception otherwise.

Each directive is a tuple of the form ``(op, attr, vals)``, where: * ``op`` identifies the modification operation to perform. One of: * ``'add'`` to add one or more values to the attribute * ``'delete'`` to delete some or all of the values from the attribute. If no values are specified with this operation, all of the attribute's values are deleted. Otherwise, only the named values are deleted. * ``'replace'`` to replace all of the attribute's values with zero or more new values * ``attr`` names the attribute to modify * ``vals`` is an iterable of values to add or delete :returns: ``True`` if successful, raises an exception otherwise. CLI Example: .. code-block:: bash salt '*' ldap3.modify "{ 'url': 'ldaps://ldap.example.com/', 'bind': { 'method': 'simple', 'password': 'secret'} }" dn='cn=admin,dc=example,dc=com' directives="('add', 'example', ['example_val'])" c S s. g | ]\}}}t td |�� �|t|�f�qS )ZMOD_)r r r7 rI )rK �oprL rM r r r rT s ��zmodify.<locals>.<listcomp>� rO r c S rP r rQ rR r r r rT � � T)Zto_strZpreserve_tuplesN) r= � enumeraterF rG rH �decoder+ �modify_sr r r )r8 r Z directivesr# rX �idx�modr r r r �modify� s( /� �����rd c C s� t | �}dd� |�� D �}dd� |�� D �}d|v r%dd� |d D �|d< tj�||�}z |j�||� W dS tjyN } z t|� W Y d}~dS d}~ww ) a� Modify an entry in an LDAP database. This does the same thing as :py:func:`modify`, but with a simpler interface. Instead of taking a list of directives, it takes a before and after view of an entry, determines the differences between the two, computes the directives, and executes them. Any attribute value present in ``before`` but missing in ``after`` is deleted. Any attribute value present in ``after`` but missing in ``before`` is added. Any attribute value in the database that is not mentioned in either ``before`` or ``after`` is not altered. Any attribute value that is present in both ``before`` and ``after`` is ignored, regardless of whether that attribute value exists in the database. :param connect_spec: See the documentation for the ``connect_spec`` parameter for :py:func:`connect`. :param dn: Distinguished name of the entry. :param before: The expected state of the entry before modification. This is a dict mapping each attribute name to an iterable of values. :param after: The desired state of the entry after modification. This is a dict mapping each attribute name to an iterable of values. :returns: ``True`` if successful, raises an exception otherwise. CLI Example: .. code-block:: bash salt '*' ldap3.change "{ 'url': 'ldaps://ldap.example.com/', 'bind': { 'method': 'simple', 'password': 'secret'} }" dn='cn=admin,dc=example,dc=com' before="{'example_value': 'before_val'}" after="{'example_value': 'after_val'}" c S rD r rE rJ r r r rN L � $ zchange.<locals>.<dictcomp>c S rD r rE rJ r r r rN M re rO c S rP r rQ rR r r r rT P r] zchange.<locals>.<listcomp>NT) r= r6 r rX Z modifyModlistr+ ra r r )r8 r �beforeZafterr# rX r r r r �change s /���rg r )r> r?
