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.

This is a set of libraries common to IPA clients and servers though mostly
geared currently towards command-line tools.
A brief overview:
config.py - identify the IPA server domain and realm. It uses python-dns to
try to detect this information first and will fall back to
/etc/ipa/default.conf if that fails.
ipautil.py - helper functions
entity.py - entity is the main data type. User and Group extend this class
(but don't add anything currently).
ipavalidate.py - basic data validation routines
