Python UDM REST Client
Python library to interact with the Univention UDM REST API, implements the interface of the Python UDM API.
Free software: GNU Affero General Public License version 3
Automatic handling of HTTP(S) sessions
100% test coverage (unittests + integration tests)
Python 3.6, 3.7, 3.8, 3.9, 3.10, 3.11
The UDM context manager opens and closes a HTTP session:
>>> import asyncio >>> from udm_rest_client.udm import UDM >>> >>> async def get_obj(mod_name, dn): ... async with UDM( ... "USERNAME", ... "PASSWORD", ... "https://FQDN.OF.UCS/univention/udm", ... ssl_ca_cert="ucs-root-ca.crt" ... ) as udm: ... mod = udm.get(mod_name) ... return await mod.get(dn) ... >>> # Python 3.6: >>> loop = asyncio.get_event_loop() >>> obj = loop.run_until_complete(get_obj("users/user", "uid=foo,cn=users,BASE-DN")) >>> >>> # Python 3.7+: >>> obj = asyncio.run(get_obj("users/user", "uid=foo,cn=users,BASE-DN")) >>> >>> print(obj) UdmObject('users/user', 'uid=foo,cn=users,BASE-DN') >>> print(obj.props.username) foo
There are more examples in the docs usage section.
If the SSL CA certificate is not available verify_ssl=False can be used in place of ssl_ca_cert=.... Obviously that is not safe! The CA of any UCS server can always be downloaded from http://FQDN.OF.UCS/ucs-root-ca.crt.
Install Python UDM REST Client via pip from PyPI:
$ pip install udm-rest-client
Install the OpenAPI client library used by the udm-rest-client. It is created by software from the OpenAPI Generator project. You need to either have a local Java installation (Java 8+) or run the projects Docker container. The process is scripted:
$ update_openapi_client --generator docker ucs.master.fqdn.or.ip # use Docker $ update_openapi_client --generator java ucs.master.fqdn.or.ip # use Java
Use --insecure to ignore SSL verification errors. See --help for more options.
Use --username and --password to provide credentials if access to your openapi.json is protected. This is the default in newer versions of UCS and thus credentials are needed.
Important: Whenever a new UDM module is installed in the domain, it is necessary to rerun update_openapi_client. The new UDM module will otherwise not be available in the Python UDM REST Client. Very few apps (like UCS@school and Open-Xchange) install new UDM modules. New extended attributes do not require to rebuild the OpenAPI client library.
There are some isolated unittests, but most tests run against a real UDM REST API. Either an existing UCS installation can be used, or a LXD container started.
Run tests with the current Python interpreter:
$ make test
Using tox the tests can be executed with all supported Python versions:
$ make test-all
Using the UCS LXD container is automated in the Makefile. It has commands to download and start the LXD image (1 GB) and running the tests:
$ make create-lxd-test-server-config $ make test
Initializing LXD is however left up to the developer (see https://linuxcontainers.org/lxd/). Using storage backend lvm, btrfs or zfs is recommended for repeated use. To run the tests only once, the storage backend dir is the easiest to use. It is very slow though, as it requires unpacking the image every time the container is started.
The Makefile also needs yq to be installed: https://github.com/mikefarah/yq
It is also possible to use an existing UCS server for the tests. Export UCS_HOST (the servers IP/FQDN), UCS_USERDN (the DN of an administrator account, usually uid=Administrator,cn=users,dc=...) and UCS_PASSWORD (the accounts password), before starting the tests:
$ export UCS_HOST="my.server.local" $ export UCS_USERDN="uid=Administrator,cn=users,dc=domain,dc=local" $ export UCS_PASSWORD="s3cr3t" $ make test
Much more comfortable (especially for repeated use) is creating a file test_server.yaml in the tests directory, which will automatically be used by the tests:
$ cp test_server_example.yaml test/test_server.yaml $ $EDITOR test_server.yaml
Don’t forget to update the OpenAPI client library before running the test against a new server:
$ update_openapi_client --generator <docker|java> --username Administrator --password s3cr3t $UCS_HOST
Run update_openapi_client --help to see further options.
To get the IP address of the running UCS LXD container execute:
$ . lxd.sh ; lxd_container_ip
Standard logging is used for tracking the libraries activity. To capture the log messages for this project, subscribe to a logger named udm_rest_client.
The UDM REST API on the UCS server logs into the file /var/log/univention/directory-manager-rest.log.

This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.
Update OpenAPI client library generator (openapitools/openapi-generator-cli) to version 5.4.0 to support Python 3.11..
Move operations succeed, when a language header is set.
Adjust objectType return value of users/self to latest UCS erratum.
Fix error handling in base_http.py.
Add the possibility to send an Accept-Language header with each request.
Handle UDM REST API doing immediate moves (without redirects) for objects without subordinates.
Pass trough UDM REST API error in CreateError and ModifyError exceptions.
Format the correlation ID as a hex value.
Send a correlation ID with each request.
Raise version of generated client library openapi-client-udm to 1.0.1.
Lower required version of click library, for compatibility with typer<0.4.0.
UCS 5.0 container for testing is now run using LXD.
Fix deprecated use of ruamel.yaml in tests.
Add process wide cache for the LDAP base of each host.
Update aiohttp to (at least) Version 3.8.1, which fixes aiohttp not honoring “no_proxy”.
Update development and testing dependencies.
Fix handling of values that are lists of dicts (e.g. dnsEntryZoneAlias of computer objects).
Fix not sending policy modifications to server.
The script to create/update the OpenAPI client update_openapi_client has been updated to use the OpenAPI Generator version 5.0.0.
The update_openapi_client script now verifies the checksum of the downloaded JAR file.
Breaking API CHANGE: The options attribute of UDM objects is now a dictionary. It mirrors the UDM REST APIs options attribute value. Before it was a list, which did not allow to disable default options (Bug #50974).
Add the possibility to provide credentials in the update_openapi_client script to download the schema file.
Update download URL of openapi-generator jar.
allow setting properties that only exist after enabling an option (Bug #50972)
fix not detecting changes in mutable property values
Mapping and Iterable interfaces were added to the object properties class. Adds item access (obj.props["key"]), obj.props.get("key"), len(obj.props), key in obj.props, obj.props.keys(), obj.props.values(), obj.props.items()
HTTP basic passwords are no longer logged
map options and policies back to original values (were being rewritten to pep8 conform keys by the OpenAPI client)
allow specifying existing JAR for open api client build
various small fixes to handle RTD and Travis-CI
