Also fic sdap_get_generic_send() to be a bit more "generic" :-)
Also figs bugs within it.
This patch allow us 2 good things.
A) we check that the server effectively supports GSSAPI auth before we try to
use it.
B) against IPA it substantially cuts delays when the server is offline because
it uses a 5 second async timeout on the connection and doesn't try to do a
slow synchronous kinit+sasl_bind if the server is not even available.

The providers are now responsible for determining how long a cached
entry is considered valid. The default is the same as before (600s)
|
|
Nested groups weren't properly handled.
Add 2 pass strategy to update groups memberships
Stuff work as expected when enumeration is enabled now.

The sdap_id_connect_* request tries to bind to an LDAP server with
the default credentials. Only the opts component of the sdap_id_ctx
context is used. A new request sdap_cli_connect_* is created which
expects only the opts pointer as parameter and not the whole context.
This makes it reusable by other providers.

Network timeouts are used in quick operations like bind.
Search timeout is used for operations that can "legally" require more time.
Change defaults to 6 and 60 seconds respectively.
|
|
- password policy request controls are send during bind and change
password extended operation
- the response control is evaluated to see if the password is expired
or will expire, soon
|
|
- this patch should fix bug #213, a double free in the sdap timeout handler
|
|
Always use the network timeout defined in the options.
But raise defaults to 60 seconds or enumerations can easily fail.
|
|
Inits krb5 credentials, if sasl mech is GSSAPI.
Tested with GSSAPI and host keytab as well as user credentials.
Updates also manpages with the new options.
|
|
Timers always come before fd events, wait 5 microseconds between processing
operations so that tevent has a chance of cactching an fd event in between.
This allows the backend to reply to pings even while processing very large ldap
results (importanty especially during the first enumeration).

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.
|
|
Authentication against a LDAP server should always use an
encrypted connection. To acchive this the LDAP provider calls
ldap_start_tls which will fail if the connection is already
encrypted, e.g. if an ldaps tunnel is already established.
Because the error message from ldap_start_tls is not specific we
check the status with ldap_tls_inplace before calling ldap_start_tls.
|
|
This patch makes basic options multiype, the init function assigns
a type from the initialization array, and processes values fetched
from confdb accordingly.
4 types are supported so far: string, number, blob and boolean
Also convert defines into enums where appropriate.
Add fetch functions that check the requested type.
|
|
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.
|
|
By attaching the reply to a subreq, we ended up freeing the operations list
element before we used it to skip to the next one.
Do not steal the context and let the unlocking code free the old reply, when it
moves onto processing the next one.
Got this one with valgrind.
|
|
After the recent changes we lost the capability to actually go offline.
Put back code that would mark the backend as offline when timeouts happen.
Make sure the enumeration code also obbeys the offline timeout, and
contributes in determining if we are offline or not.
|
|
Make counter for used messages explicit.
|
|
Check if the timestamp argument of sdap_save_group_recv is NULL before
using it.
|
|
sdap_get_initgr_process() was using the wrong sdap_id_map struct
when creating the searchfilter for the initgroups() call.
|
|
|
|
Always immediately return to DP, and update users/groups in the background.
Also implements an optimization to retrieve only changed/new users/groups
by filtering using the modifyTimestamp after the first query.
|
|
First pass to remove the legacy option and make it just a property of the
provider
|
|
Try as hard as possible to store as much data as we can.
|
|
- making the realm part upper case is now optional and done in the
LDAP backend
- using a username@realm UPN is now optional
|
|
If available the original DN and the user principle will be stored
in sysdb.
|
|
|
|
|
|
Retrieving ldap results and storing users could sometimes results in race
conditions where the final ldap result was retrieved before the store operations
where finished resulting in the operations to be aborted before termination.
Implement a serialization mechanism per operation.

The sdap_handle might be freed when processing a message.
Rearrange data flow so that the sdap_handle is never used after
a message is processed but a new event (dependent on the handle) is
instead scheduled. If the sdap_handle is freed, the scheduled event
is also removed and not fired
|

|
The way openldap libraries work, require to have a single engine per
connection as all replies are read at the same time. So we need to
always read anything that comes in from the wire and then loop to
dispatch results to the requests that are waiting.
|
|
This uses and exapands the async helpers.
|
|
|
|
These functions use the tevent_req async model, where a pair
of _send/_recv functions pilot requests, with additional helpers
like _done functions, and where needed multiple stage helpers.
