Some plugins, notably dns, modifies a returned entry in order
to compare it to the user-provided info (e.g. dnsrecord-del).
This modification was done on the cached entry directly rather
than a copy which caused unexpected results, mostly
EmptyResult because the cached entry was changed directly so
the next get_entry returned the same modified entry.
In addition, on a hit in the LDAP cache the entire cached entry
was returned regardless of what attributes were requested.
The automember condition add/remove calls only request the
inclusive/exclusive rule attributes and loop over the returned
values to look for duplicates. This was failing because the queried
entry contains attributes that the candidate entry does not contain.
The automember code is:
old_entry = ldap.get_entry(dn, [attr])
for regex in old_entry.keys():
if not isinstance(entry_attrs[regex], (list, tuple)):
old_entry, returned from the cache, contained objectclass, cn,
description, etc. which don't exist in the candidate entry so
entry_attrs[regex] threw a KeyError.
To return a copy of the entry and requested attributes on a
search HIT.
Also be more careful when storing the attributes in the cache entry.
The returned attributes may not match the requested. So store the
attributes we actually have.
This issue was exposed by Ansible which maintains a larger and
longer-lived cache because commands are executed in the server context
one after another, giving the cache a chance to build up.
Adjust the expected test results as well. In test_get_testuser()
the first request asks for all attributes (default) so ensure
that is successful since a user_add gets all attributes in
the post_callback. Next request a subset of the attributes which
is also a hit and confirm that only those requested were returned.

FreeIPA Server
FreeIPA allows Linux administrators to centrally manage identity, authentication and access control aspects of Linux and UNIX systems by providing simple to install and use command line and web based management tools.
FreeIPA is built on top of well known Open Source components and standard protocols with a very strong focus on ease of management and automation of installation and configuration tasks.
FreeIPA can seamlessly integrate into an Active Directory environment via cross-realm Kerberos trust or user synchronization.
Benefits
FreeIPA:
- Allows all your users to access all the machines with the same credentials and security settings
- Allows users to access personal files transparently from any machine in an authenticated and secure way
- Uses an advanced grouping mechanism to restrict network access to services and files only to specific users
- Allows central management of security mechanisms like passwords, SSH Public Keys, SUDO rules, Keytabs, Access Control Rules
- Enables delegation of selected administrative tasks to other power users
- Integrates into Active Directory environments
Components
The FreeIPA project provides unified installation and management tools for the following components:
- LDAP Server - based on the 389 project
- KDC - based on MIT Kerberos implementation
- PKI based on Dogtag project
- Samba libraries for Active Directory integration
- DNS Server based on BIND and the Bind-DynDB-LDAP plugin
