The patch adds 4 new calls to the NSS responder:
- SSS_NSS_GETSIDBYNAME
- SSS_NSS_GETSIDBYID
- SSS_NSS_GETNAMEBYSID
- SSS_NSS_GETIDBYSID
to either return the SIDs of the requested object or map the SID to the
name or the POSIX ID of the related object.
|
|
This patch add the functionality to handle lookup by SIDs and lookups
for SIDs to the subdomain branch of the IPA ID provider.
|
|
This patch added auto configuration SUDO with ipa provider and compat tree.

Before the recent changes, the variable was set to 0 too because it used
to be part of a structure allocated with talloc_zero.

tests_set_cwd is used and relativepath calculation method is changed and is made general based on
basedir.
|
|
If configure isn't being run with argument --with-test-dir, then variable
TEST_DIR will be defined, but its value will be empty (""). In this case
opendir will fail with uncatched error "Directory does not exist, or name is
an empty string". Finally function call dirfd will segfault because its
argument is NULL.
I changed default value of TEST_DIR (if --with-test-dir was not used).
Function tests_set_cwd does not ignore return value of chdir, because
TEST_DIR should not be the empty string.

Currently the POSIX ID or the user name are passed in different
parameters to some calls. The method will get cumbersome and error-prone
if new parameters like, e.g. the SID, are added. This patch adds a union
to hold the different kind of parameters.
|
|
|
|
Two new calls are added to allow to add SID based lookups to the
negative cache.
|
|
The patch add a new sysdb to find objects based on their SID. Currently
only the basic attributes needed to map SIDs to POSIX IDs and names are
requested, but this list can be extended for future use cases.
|
|
This new call is similar to responder_get_domain() but uses the domain
SID as search parameter. Since the length of the stored domain SID is
used in the comparison, SIDs of users and groups and be used directly
without stripping the RID component.
The functionality is not merged into responder_get_domain() to allow to
calculate the timeout correctly and return a specific error code if the
entry is expired.
|
|
This allows the nss responder to use libsss_idmap to convert between
different SID representations.
|
|
The patch adds two new request types for SID related requests. The first
one is used if a SID is given and the corresponding object should be
found. The second one can be used if the SID for an object is requested
but it is not clear if the object is a user or a group.
|
|
This patch add a new filter type to the data-provider interface which
can be used for SID-based lookups.
|
|
Currently the string representation of a SID is only stored in the cache
for debugging purpose if SID based ID-mapping is used. This patch
unconditionally stores the SID if available to allow SID-to-name
mappings from the cache.

The current timout calculation code in responder_get_domain() is flawed
and I think it always was. I removed the related code because
- it currently has no effect, a match is returned even if it is expired
- that callers do not have any code to handle expired domains.
|
|
Recent refactoring introduced to concept of disabled domains, i.e.
domains which does not exists anymore. responder_get_domain() should not
return disabled domains.
|
|
Recent refactoring removed the need to copy the domain info data of
sub-domains because the related objects will not be removed from memory
anymore.

This request takes discovery domain for primary servers and other
domain for backup servers and returns list of primary and backup
servers.
If primary domain is not reachable, it returns servers found in
backup domain as primary servers.

Due to a comparison error, the last warning when an LDAP password was in

When SSSD is not enumerating (which is the default), we are trying to
link any "ghost" entries with a newly created user entry. However, when
enumeration is on, this means a spurious search on adding any user.

Calculation of range for domains is moved from
sdap_idmap code to sss_idmap code. Some refactoring
have been done to allow this move.

is modified and correct ini interface is chosen.

In SSSD, we use dlopen() and dlsym() in two files
src/providers/data_provider_be.c and src/providers/proxy/proxy_init.c.
Hence we should explicitly link with -ldl also in simple_access-tests.
SSSD can be compiled with two crypto libraries nss or libcrypto. NSS has
dependency nspr which depends on "libdl and libpthread" This is a reason why
compilation of test did not fail even if -ldl was not explicitly added to
simple_access_tests_LDADD. But libcrypto doesn't depend on libdl, so in
this case compilation of tests will not be successful.
Upstream nspr 4.9 has two ways have to obtain metainformation about
libraries
pkg-config and own script nspr-config. First one doesn't list "-ldl"
"-lpthread" but second one lists both "-ldl" "-lpthread"
That's also why the Ubuntu maintainer found this bug -- Fedora has got
patched version of nspr, but Debian (Ubuntu) doesn't

Enterprise principals are currently most useful for the AD provider and
hence enabled here by default while for the other Kerberos based
authentication providers they are disabled by default.
If additional UPN suffixes are configured for the AD domain the user
principal stored in the AD LDAP server might not contain the real
Kerberos realm of the AD domain but one of the additional suffixes which
might be completely randomly chooses, e.g. are not related to any
existing DNS domain. This make it hard for a client to figure out the
right KDC to send requests to.
To get around this enterprise principals (see
http://tools.ietf.org/html/rfc6806 for details) were introduced.
Basically a default realm is added to the principal so that the Kerberos
client libraries at least know where to send the request to. It is not
in the responsibility of the KDC to either handle the request itself,
return a client referral if he thinks a different KDC can handle the
request or return and error. This feature is also use to allow
authentication in AD environments with cross forest trusts.

Different user and group lookup requests used nearly identical code,
this patch unifies some of the related code paths.

The task of get_my_domain_data() is to read some information about the
configured domain from the cache. While the sysdb interface was
redesigned some changes changed the behaviour so that the data of the
domain of the current request was read. If this domain is a sub-domain
the wrong data was read. As a result group-memberships of the configured
domain were not taken into account.
The original code didn't made it easy to see that always the parent
domain should be used here, because there was no comment indication this
and the function name get_my_domain_data() didn't made it clear either.
Additionally to fixing the issue this patch also adds a comment and
rename the function to get_parent_domain_data().

It makes sense to keep using the boolean for access granted/denied, but
when the user/group is not found, the request would now return
ERR_ACCOUNT_UNKNOWN

One peculiarity of the sysdb_attrs_get_el interface is that if the
attribute does not exist, then the attrs array is reallocated and the
element is created. But in case other pointers are already pointing
into the array, the realloc might invalidate them.
Such case was in the sdap_process_ghost_members function where if
the group had no members, the "gh" pointer requested earlier might have
been invalidated by the realloc in order to create the member element.

* Rename common_check.c to leak_check.c

sss_mc_set_recycled is a static function, that should not
be used outside nsssrv_mmap_cache.c. The sss_cache tool
is an exception, because in the case when sssd is not running,
sss_cache must invalidate the memory cache file. That is why
sss_mc_set_recycled was copied to the tools_mc_util.c
(as helper function for sss_memcache_invalidate function).
It was duplicated to allow this function to remain static
(and invisible to any .h files), so that it is not used anywhere else.
Wrong usage of this function might cause race conditions and corrupt
the cache.
I'll add comments about the duplication to the code.

In the simple access provider, we need to only canonicalize user names when
comparing with values in the ACL, not when searching the cache. The sysdb
searches might do a base search with a DN constructed with the username
which fails if the username is lower case.
