The providers are now responsible for determining how long a cached
entry is considered valid. The default is the same as before (600s)
|
|
|
|
This converts a great many configuration options to the new
standard format.
|
|
Fixes a segfault seen in the wild with providers=files

This reverts commit 8c50bd085c0efe5fde354deee2c8118887aae29d.
Amended: commit 1016af2b1b97ad4290ccce8fa462cc7e3c191b2e also made
use of the SYSLOG_ERROR() macro, so those portions of that code
also needed to be reverted.

This is just a band-aid until ELAPI is fully functional and ready to
use.
|
|
There was a chance that groups w/o members could end up causing a failure to
store the group. This would happen in case the structure used by glibc to fill
up the group data was "dirty". Always memset structures before passing them to
te libc and also check if there are any members, before calling the async
function.
Finally add some tracing at level 7 so that it is easier to follow what is going
on in case of touble.

Add helpers functions to query/set the offline status per backend.
Now all providers share the same offline status.
|
|
The code was still dependent on it for the ldap driver.
Changed the driver code to depend on the schema type.
Fix defaults for user and groups trees.
ATM if you use the rfc2307bis schema you have to put users and groups
in 2 separate trees (what people does by default anyway.
If this limitation will turn to be too hard, we will change this later.

New tevent library finally outlawed nested loops.
|
|
|
|
Previously, we had hardcoded the paths for the NSS, PAM and
private PAM sockets to /var/lib/sss/pipes. With this patch, we
will specify the sockets with --with-pipe-path.
|
|
Also add tests

This is part of a set of patches to rewrite sysdb to a hopefully better
API, that will also let use use tevent_req async style calls to manipulate
our cache.
|
|
This sysdb_req has always really been a transaction handle and not
a request.
This is part of a set of patches to rewrite transaction support in sysdb to a
hopefully better API, that will also let use use tevent_req async style to
manipulate our cache.

The libPath should be constructed from the libName. There is no
benefit to specifying it separately.
|
|
The old function was not used anywhere, and this function uses better
semantics, including not using void ** which gives strict aliasing problems.
Also add a generic password destroy function
|
|
|
|
This will blackout any request to the backend for 15 seconds, then
will allow again to retry.
|
|
Convert auth modules to do the caching themselves
|
|
When a user from a domain served by the proxy backend changes his
password with passwd the passwd command asks for the old password,
but it is not validated by the pam_chauthtok call in the proxy
backend, because it is running as root.
If the request is coming the unpriviledged socket we now call
pam_authenticate explicitly before pam_chauthtok.
|
|
Change sysdb to always passwd sss_domain_info, not just the domain name.
This way domain specific options can always be honored at the db level.
|
|
The same module may implement both types, but initializatrion will be
nonetheless performed separately, once for the identity module and once for the
authenticator module.
Also change the proxy module to retireve the pam target name from the domain
configuration so that it is possibile to create per-domain pam stacks.
With this modification it is actually possibile to use normal nss and pam
modules to perform a successful authentication (tested only with sudo so far)
Update exmples.

Makes LOCAL a normal backend removing some special handling.
Fix/Add id range filtering and name filtering
Filters uid=0 and gid=0 in the proxy backend as 0 is invalid within
sysdb and was causing getxxent calls to fail completely.
Fix nss_ncache_check_xxx calls to avoid dirtying the 'ret' variable and
causing some unwanted failures.
Change sysdb to always return the uid number when searching member entries so
that id range filtering can be perfomed also in group searhes (does not work
with legacy backends)

dependencies based on the latest samba code.
Convert all references to the old events library to use the
renamed tevent library.
|
|
Also move responders under server/responder with shared code
in server/responder/common

types of domains: modern and legacy
modern uses member/meberof, legacy uses memberUid for group
memberships.
Rework the proxy backend to use the legacy style as that's the
format the data comes in (trying to convert would require too
many transformations and increased the number of queries).
Add support for fetching groups in nss.
Add support for enumerating users and groups (requires to enable enumeration
in config) both in nss and in the proxy provider.
Remove confdb_get_domain_basedn() and substitute with generic calls in
the nss init function.
Store a domain structure in the btree not the basedn so that we can add
enumeration flags.
Also make sure NSS understand how to make multiple calls on
enumerations, also make passing the domian parameter always
mandatory, passing in domain=* is not valid anymore.
This work fixes also a few memory, degfault, and logic bugs
found while testing all nss functions (there are still some to
fix that are less critical and much harder to find yet).

use the same namespace (sysdb_posix_)
- no need to explicitly start a transaction if only one
operation is performed using a synchronous interface
- split _add_remove_ functions into separate functions,
don't let ldap madness creep into out interfaces
|
|
rename everything with the sysdb suffix.
|
|
|
|
libnss library through config directives on the domain object
