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
its grace period was never displayed.

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

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.

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.

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.

In krb5-libs >= 1.11, function krb5_cc_resolve verify if credential cache dir
exists. If it doesn't exist, than it will be created with process permissions
and not user permissions.
Function cc_residual_is_used has already checked for non existing
directory, but it wasn't considered to be a failure and therefore next call
of krb5_init_context will create directory with wrong permissions.
Now if directory doesn't exist, it will be handled like there was not ccache
attribute in sysdb cache. We also check if "primary" file in ccache directory
has right permissions. But we ignore missing "primary" file.

We set a plugin during an initialization of ID provider, which
is an authoritative provider for a plugin choice. The plugin is
set only once. When other provider is initalized (e.g. id = IPA,
sudo = LDAP), we do not overwrite the plugin.
Since sssm_*_id_init() is called from all module constructors,
this patch relies on the fact, that ID provider is initialized
before all other providers.

Removes hard coded SRV lookup code with a plugin call. This patch
breaks SRV lookups as there is currently no plugin in use. It is
fixed in next patch.

https://fedorahosted.org/sssd/ticket/1032
This plugin mimics the current behaviour.
If discovery_domain is set it is the only domain that is tried.
If discovery_domain is not set, we try to autodetect domain first
and if that fails or SRV lookup on this domain fails, we fallback
to SSSD domain name.

https://fedorahosted.org/sssd/ticket/1032
Introduces two new error codes:
- ERR_SRV_NOT_FOUND
- ERR_SRV_LOOKUP_ERROR
Since id_provider is authoritative in case of SRV plugin choise,
ability to override the selected pluging during runtime is not
desirable. We rely on the fact that id_provider is initialized
before all other providers, thus the plugin is set correctly.

We never need to regain root after we call become_user() so tighten up even
further our privilege drop.
Add a setgroups() call to remove all secondary groups root may have been given
for whateve reason. Then use the setres[ug]id function to also drop the saved
uid/gid so the process cannot regain back root id.
Capabilities are also implicitly dropped here, no more CAP_SETUID so this is a
Point of No Return, once changed to non-root the process can't get back.
Remove redefinition of sys/types.h and unistd.h, they are already defined in
util.h and they need to be included after _GNU_SOURCE/_BSD_SOURCE is defined
or the prototypes for setres[ug]id will not be found.
Add grp.h after util.h for the same reason.

Definition of structure sss_auth_token was removed from header file
authtok.h and there left only declaration of this structure.
Therefore only way how to use this structure is to use accessory function from
same header file.
To creating new empty authotok can only be used newly created function
sss_authtok_new(). TALLOC context was removed from copy and setter functions,
because pointer to stuct sss_auth_token is used as a memory context.
All declaration of struct sss_auth_token variables was replaced with
pointer to this structure and related changes was made in source code.
Function copy_pam_data can copy from argument src which was dynamically
allocated with function create_pam_data() or zero initialized struct pam_data
allocated on stack.
https://fedorahosted.org/sssd/ticket/1830

|
Function create_pam_data() should be only one way how to create new
struct pam_data, because it also initialize destructor to created
object.

1. initialization (main-req), returns members of input group
2. evaluate group members (group)
3. perform individual search (no-deref) or dereference attribute (deref)
4a. no-deref
1. perform a lookup depending on the type of the member object
2. all direct members are evaluated first
3. then we step down in nesting level and evaluate nested groups
4b. deref
1. perform a dereference lookup on member attribute
2. all direct members are evaluated first
3. then we step down in nesting level and evaluate nested groups

Add option to fallback to fetch local users if rfc2307is being used.
This is useful for cases where people added local users as LDAP members
and rely on these group memberships to be maintained on the local host.
Disabled by default as it violates identity domain separation.

Also simplify sdap_access_send to avoid completely fake _send() routines.

Changes the simple access provider's interface to be asynchronous. When
the simple access provider encounters a group that has gid, but no
meaningful name, it attempts to resolve the name using the
be_file_account_request function.
Some providers (like the AD provider) might perform initgroups
without resolving the group names. In order for the simple access
provider to work correctly, we need to resolve the groups before
performing the access check. In AD provider, the situation is
even more tricky b/c the groups HAVE name, but their name
attribute is set to SID and they are set as non-POSIX
|
|
The simple access provider unit tests now need to link against the Data
Provider when they start using the be_file_account_request() function.
But then we would start having conflicts as at least the main()
functions would clash.
If UNIT_TESTING is defined, then the data_provider_be.c module does not
contain the main() function and can be linked against directly from
another module that contains its own main() function
|
|
In order to resolve group names in the simple access provider we need to
contact the Data Provider in a generic fashion from the access provider.
We can't call any particular implementation (like sdap_generic_send())
because we have no idea what kind of provider is configured as the
id_provider.
This patch splits introduces the be_file_account_request() function into
the data_provider_be module and makes it public.
A future patch should make the be_get_account_info function use the
be_get_account_info_send function.

Option ipa_selinux_refresh is added to basic ipa options.

Reuse cached SELinux maps when they are requested
within time interval (in this patch it is hardcoded to
be 5 seconds).
https://fedorahosted.org/sssd/ticket/1744
|
|
The SELinux processing was distributed between provider and
pam responder which resulted in hard to maintain code. This
patch moves the logic to provider.
IT ALSO REQUIRES CHANGE IN THE SELINUX POLICY, because
the provider also writes the content of selinux login
file to disk (which was done by responder before).

Header file "providers.h" is not included in any other
file and function "dp_process_init" declared in this header file
has no implementation.
Header file protos.h is not also included in any other file and even
hole content is commented out.
