* Remove two unused functions.Stephen Gallagher2009-10-151-8/+0
| | | | | | These functions were used when reconnecting to the DP after losing the connection. Since there is no DP any longer, there's no reason to have these functions.
* Remove DP processSimo Sorce2009-10-091-16/+16
| | | | | Turn the backend process into data provider servers Make Frontends (pam, nss) directly attach to the backends
* Remove unused btreemap codeStephen Gallagher2009-10-061-1/+0
| | | | | We have converted to using dhash in place of btreemap everywhere in the code.
* Fix infinite loop with empty group enumerationStephen Gallagher2009-09-291-13/+15
| | | | | | Loop control variable was not being incremented. I also converted a goto loop into a do...while loop to make it easier to follow the logic.
* Send debug messages to logfileJakub Hrozek2009-09-251-1/+3
| | | | | | | | | | | | | Introduces a new option --debug-to-files which makes SSSD output its debug information to a file instead of stderr, which is still the default. Also introduces a new confdb option debug_to_files which does the same, but can be specified per-service in the config file. The logfiles are stored in /var/log/sssd by default. Changes the initscript to log to files by default.
* Upgrade confdb to version 2Stephen Gallagher2009-09-252-23/+41
| | | | | This converts a great many configuration options to the new standard format.
* Revert "Use syslog for logging error conditions in SSSD"Stephen Gallagher2009-09-232-44/+36
| | | | | | | | 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.
* Use syslog for logging error conditions in SSSDJakub Hrozek2009-09-212-36/+44
| | | | | This is just a band-aid until ELAPI is fully functional and ready to use.
* Fix getgrnam and getgrgid callsSimo Sorce2009-09-111-7/+9
| | | | | The patch that added check_cache() broke them, no results returned for any group with actual members ...
* Add support for the EntryCacheNoWaitRefreshTimeoutStephen Gallagher2009-09-093-2/+53
| | | | | | | | This timeout specifies the lifetime of a cache entry before it is updated out-of-band. When this timeout is hit, the request will still complete from cache, but the SSSD will also go and update the cached entry in the background to extend the life of the cache entry and reduce the wait time of a future request.
* Consolidate cache lookups in the NSSStephen Gallagher2009-09-091-177/+93
| | | | | | getpwnam, getpwuid, getgrnam and getgrgid will now use a common function, check_cache, for determining whether to return a cached value or to go to the provider.
* Split database in multiple filesSimo Sorce2009-09-081-22/+183
| | | | | The special persistent local database retains the original name. All other backends now have their own cache-NAME.ldb file.
* Fix two possible uninitialized valuesSimo Sorce2009-09-081-3/+4
| | | | Make counter for used messages explicit.
* Turn enumeration into a boolean valueSimo Sorce2009-08-312-8/+4
|
* Fix group replies when using member/memberofSimo Sorce2009-08-271-191/+139
| | | | Also remove legacy memberuid support
* fix handling of filtersUsers in groupsSumit Bose2009-08-213-31/+44
| | | | | | | | - with the boolean option filterUsersInGroups it can be controlled wether filtered users appear in groups or not. - fixed an error which prevented the display of groups with filtered members - removed some tab indents
* Fix reconnection codeSimo Sorce2009-08-171-16/+24
| | | | | | | Remove redundant reconnection code that was interfeering with the sbus reconnection code. Consolidate include files for sbus relates operations. Make pamsrv code similar to nsssrv code.
* Refactor responder_dp.cStephen Gallagher2009-08-141-20/+20
| | | | | | Many of the functions in responder_dp.c were originally NSS- specific and were moved there from the NSS responder code. Since they are now generic to any responder, rename them to sss_dp_*
* Change the why DP clients identifySimo Sorce2009-08-113-85/+15
| | | | Mirrors what we have done with the monitor.
* Change services identification mechanismSimo Sorce2009-08-111-74/+5
| | | | | | | Let services identify themselves voiluntarily as the first operation instead of polling from the monitor. Also consolidate some common functions and make them available as monitor helpers.
* Make child processes exit when parent diesJakub Hrozek2009-08-111-0/+6
| | | | | | | | The child processes call prctl() and when their parent process is killed, they are sent SIGTERM using prctl. This is currently Linux-specific, for non-Linuxes, a similar effect is achieved by catching a set of common termination signals and sending SIGTERM to the process group.
* Make socket paths a compile-time optionStephen Gallagher2009-08-111-1/+0
| | | | | | 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.
* Simplify interfaces initializationSimo Sorce2009-08-103-23/+30
| | | | | | | Make as much as possible static, and remove use of talloc_reference and allocation/deallocation of memory when not necessary. Fix also responder use of rctx->conn, was mistakenly used for both monitor and dp connections.
* Cosmetic changesSimo Sorce2009-08-102-17/+17
| | | | | Rationalize and rename connection names in preparatoin for merging of server and connection structures.
* Remove redundant memory contextsSimo Sorce2009-08-101-3/+3
| | | | Simplify code by removing stuff that is never used or redundant.
* Implement resInit for monitor, NSS, PAM, DP and the backendsStephen Gallagher2009-07-201-0/+20
|
* Fix user enumeration bugSimo Sorce2009-05-281-4/+0
| | | | | | The previous patch to fix an enumeration bug found with group enumeration inadvertently introduced a bug with user enumeration. Yeah, almost funny!
* Fix enumerations (bug #42)Simo Sorce2009-05-271-12/+76
| | | | | | | | | | If a backend had all its results filtered in fill_pwent or fill_grent then we would return an empty result, which means "end of results" to the client. Now we return ENOENT and let callers decide what to do. Also make sure we do not grow packets unless we are going to fill them as that's a recipe for killing the client as the size passed to sss_packet_grow is used to determine the size of the final packet.
* Silence warningsSimo Sorce2009-05-262-4/+8

* Do not fire up backend search when the data provider is localJakub Hrozek2009-05-261-14/+14
|
* added more flexible handling of client protocolSumit Bose2009-05-151-0/+10
| | | | | - allow different protocol versions for PAM and NSS - support more than one protocol version in the responder
* Fix some more return paths using uninitalized retSimo Sorce2009-05-061-3/+3
|
* Fix use of uninitialized return variableSimo Sorce2009-04-291-5/+5
|
* Force user check and discover user's domainSimo Sorce2009-04-172-278/+0
| | | | | | | | | | | Force a user lookup against the users domain provider. If a user domain is not specified search though all non fully qualifying domains. Perform authentication against the corrent domain auth backend, based on the user's domain found in the lookup if one was not specified. Also move the NSS-DP functions in COMMON-DP as they are reused by the PAM responder too now.
* Fix by_id enumeration with multiple domainsSimo Sorce2009-04-161-0/+10
| | | | | | We need to stop parsing domains as soon as a caaandidate is found and let the callback search additional domains if the id is not found. Should fix ticket #21
* Add common function to retrieve comma sep. listsSimo Sorce2009-04-141-11/+13
| | | | | | Also convert all places where we were using custom code to parse config arguments. And fix a copy&paste error in nss_get_config
* Make reconnection to the Data Provider a global settingStephen Gallagher2009-04-141-5/+2
| | | | | | | Previously, every DP client was allowed to set its own "retries" option. This option was ambiguous, and useless. All DP clients will now use a global option set in the services config called "reconnection_retries"
* Add reconnection code between the NSS responder and the Data providerStephen Gallagher2009-04-141-1/+52
|
* Fix a couple of segfaults and timeout checksSimo Sorce2009-04-131-30/+13
|
* Fix segfaults when passing an unknown domainSimo Sorce2009-04-131-9/+20
| | | | | Also setting dctx->domain to NULL is a recipe for segfaults :-) Assign dctx->domain only when dom actually holds a domain pointer.
* Serialize requests vs backends.Simo Sorce2009-04-091-544/+702
| | | | | | | This way we do not waste resources starting searching for users/groups in multiple backends when the first one has the answer. Also prevents possible race conditions where a user named the same way is found in multiple backends and the wrong one is returned.
* Change the way we retrieve domainsSimo Sorce2009-04-082-177/+87
| | | | | | | | | | | | | To be able to correctly filter out duplicate names when multiple non-fully qualified domains are in use we need to be able to specify the domains order. This is now accomplished by the configuration paramets 'domains' in the config/domains entry. 'domains' is a comma separated list of domain names. This paramter allows also to have disbaled domains in the configuration without requiring to completely delete them. The domains list is now kept in a linked list of sss_domain_info objects. The first domain is also the "default" domain.
* Clean up warnings in SSSDStephen Gallagher2009-04-071-8/+8
|
* Unify name parsing and reposnder headersSimo Sorce2009-04-073-149/+146
| | | | | | Use common sss_parse_name function in all responders Simplify responder headers by combining common,cmd,dp in one header and add name parse structure as part of the common responder context.
* Add way to use files as a proxy backend fro LOCALSimo Sorce2009-04-011-28/+91
| | | | | | | | | | | | 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)
* Add a more flexible way to parse and filter names.Simo Sorce2009-04-015-280/+885
| | | | | | | | | | A new nss_parse_name function uses pcre to parse names, this makes it possible, in future, to make the filter user configurable. Add a new filter mechanism to filter out users that uses the negative cache by setting a permanet negative entry. Rework the entry points where the negative cache is checked for.
* Fix potential segfault if dp_ctx is still NULL.Simo Sorce2009-03-271-0/+9
| | | | | | | May happen at startup if, for some reason dp is very slow to start and we receive a request before a reconnection is rescheduled in the responder dp reconnection code. This shouldn't happen normally so make it clear with a debug statement.
* Make nsssrv use the common responder functionsSimo Sorce2009-03-274-687/+200
| | | | | Make nss_ctx a private pointer of the common resp_ctx Use sss_process_init and remove all duplicate functions from nsssrv.c
* Fix uninitailized pointer and cut&paste errorSimo Sorce2009-03-271-1/+5
| | | | | | | The structure we copy the domain pointerr on is not zero when allocated. We need to zero it ourselves or we get segfaults later on. A cut&paste error caused us to call the wrong getpw function.
* Fix buildSimo Sorce2009-03-242-1/+4
| | | | forgot to commit a few changes
