2013-06-07AD: Add additional service to support Global Catalog lookupsJakub Hrozek3-33/+178
When fixed host names of AD servers are configured in the config file, we can't know (unlike when service discovery is at play) if the servers are Global Catalogs or not. This patch adds a private data to servers read from the config file that denote whether the server can be tried for contacting the Global Catalog port or just LDAP. The GC or LDAP URIs are generated based on contents of this private data structure. Because SSSD sticks to a working server, we don't have to disable or remove the faulty GC servers from the list.
2013-06-07LDAP: Do not store separate GID for subdomain usersJakub Hrozek1-10/+18
As the subdomains are MPG domains, we don't want to store a separate GID for the subdomain users, but rather just create a UPG.
2013-06-07Split generating primary GID for ID mapped users into a separate functionJakub Hrozek1-41/+70
Move the part of sdap_save_user into a separate function so that it can be special cased an only called for users in primary domains, not subdomain users.
2013-06-07LDAP: store FQDNs for trusted users and groupsJakub Hrozek5-12/+36
Because the NSS responder expects the name attribute to contain FQDN, we must save the name as FQDN in the LDAP provider if the domain we save to is a subdomain.
2013-06-07LDAP: split a function to create search basesJakub Hrozek2-29/+73
This function will be used later to fill the sdap_domain structures with search bases.
2013-06-07Move domain_to_basedn outside IPA subtreeJakub Hrozek2-65/+0
The utility function will be reused to guess search base from the base DN of AD trusted domains.
2013-06-07LDAP: return sdap search return code to IDJakub Hrozek5-50/+126
By default, the LDAP searches delete the entry from cache if it wasn't found during a search. But if a search wants to try both Global Catalog and LDAP, for example, it might be beneficial to have an option to only delete the entry from cache after the last operation fails to prevent unnecessary memberof operations for example.
2013-06-07LDAP: new SDAP domain structureJakub Hrozek25-145/+315
Previously an sdap_id_ctx was always tied to one domain with a single set of search bases. But with the introduction of Global Catalog lookups, primary domain and subdomains might have different search bases. This patch introduces a new structure sdap_domain that contains an sssd domain or subdomain and a set of search bases. With this patch, there is only one sdap_domain that describes the primary domain.
2013-06-07LDAP: Pass in a connection to ID functionsJakub Hrozek8-31/+64
Instead of using the default connection from the sdap_id_ctx, allow the caller to specify which connection shall be used for this particular request. Again, no functional change is present in this patch, just another parameter is added.
2013-06-07LDAP: Refactor account info handler into a tevent requestJakub Hrozek2-163/+210
The sdap account handler was a function with its own private callback that directly called the back end handlers. This patch refactors the handler into a new tevent request that the current sdap handler calls. This refactoring would allow the caller to specify a custom sdap connection for use by the handler and optionally retry the same request with another connection inside a single per-provider handler. No functional changes are present in this patch.
2013-06-07LDAP: sdap_id_ctx might contain several connectionsJakub Hrozek23-115/+175
With some LDAP server implementations, one server might provide different "views" of the identites on different ports. One example is the Active Directory Global catalog. The provider would contact different view depending on which operation it is performing and against which SSSD domain. At the same time, these views run on the same server, which means the same server options, enumeration, cleanup or Kerberos service should be used. So instead of using several different failover ports or several instances of sdap_id_ctx, this patch introduces a new "struct sdap_id_conn_ctx" that contains the connection cache to the particular view and an instance of "struct sdap_options" that contains the URI. No functional changes are present in this patch, currently all providers use a single connection. Multiple connections will be used later in the upcoming patches.
2013-06-07Do not obfuscate calls with booleansJakub Hrozek4-31/+93
Instead of using boolean variables to denote whether the call is adding a primary or a secondary server, use a function wrapper that tells what it's doing by its name.
2013-06-06Always send the PAC to the PAC responderSumit Bose1-20/+18
Currently while doing a Kerberos based authentication the PAC was only send to the PAC responder for principals from a different realm. This reflects the FreeIPA use case of users from trusted domains. This restriction does not make sense anymore when the data from the PAC should be used for the AD provider as well. It also makes only limited sense for the IPA use case, because when using GSSAPI the PAC of users from the local IPA domain are already evaluated by the PAC responder.
2013-06-06Intermittent fix for get_user_and_group_users_doneSumit Bose1-3/+0
users_get_recv() never returns ENOENT. In general it should return EOK in the case no matching user was found. But since I forget to handle a SID based filter properly in sdap_get_users_process() an error is returned in this case which makes get_user_and_group_users_done() work as expected with this patch. There is an upcoming enhancement to users_get_recv() which I'm planning to use for a full fix.
2013-06-04Use queue for get_subdomainsSumit Bose1-3/+7
It does not make much sense to run multiple get_subdomains request in parallel because all requests will load the same information from the server. The IPA and AD provider already implement a short timeout to avoid the multiple requests are running to fast after each other. But if the timeout is over chances are that if two or more request come in fast the first request cannot update the timeout and request will run in parallel. To avoid this the requests are queued and send one after the other to the provider.
2013-06-04Add be request queueSumit Bose2-0/+130
For some backend targets it might be not desirable to run requests in parallel but to serialize them. To avoid that each provider has to implement a queue for this target this patch implements a generic queue which collects incoming requests before they are send to the target.

2013-05-31Set canonicalize flag if enterprise principals are usedSumit Bose1-1/+6
In contrast to MIT KDCs AD does not automatically canonicalize the enterprise principal in an AS request but requires the canonicalize flags to be set. To be on the safe side we always enable canonicalization if enterprise principals are used.

https://fedorahosted.org/sssd/ticket/1950
2013-05-30Add utility functions for formatting fully-qualified namesJakub Hrozek1-4/+4
Instead of using printf-like functions directly, provide two wrappers that would encapsulate formatting the fully-qualified names. No functional change is present in this patch.

2013-05-28IPA: Check for ENOMEMJakub Hrozek1-0/+3
2013-05-27Fix dyndns timer initializationJakub Hrozek6-10/+34
The dyndns init function was starting the timer even if the updates were set to False. This patch splits the init of dynamic updates and the timer into two functions so that the back end can start the updates separately from reading the options.
2013-05-27Fail with misconfigured id-mapping rangesOndrej Kos1-1/+2
https://fedorahosted.org/sssd/ticket/1930 On misconfigured id-mapping range variables, the provider should not start. We were internally correctly setting error code for failure, but interruption of startup was not performed. Also raised the debug level of message for this misconfiguration.
2013-05-27Add SID related requests to the LDAP providerSumit Bose1-5/+230
The patch adds support for BE_REQ_BY_SECID and BE_REQ_USER_AND_GROUP to the LDAP provider. Since the AD and the IPA provider use the same code they support those request now as well. Besides allowing that users and groups can be searched by the SID as well the new request allows to search users and groups in one run, i.e. if there is not user matching the search criteria groups are searched as well.
2013-05-27IPA: read user and group SIDSumit Bose1-2/+2
To allow mapping of SIDs to names or POSIX IDs and back the related attributes must be read from the FreeIPA directory server.
2013-05-27Handle SID strings in sdap_attrs_get_sid_str() as wellSumit Bose1-9/+20
This patch add a basic check if the SID returned by the LDAP server is in a string representation. If not it is assumed that a binary SID was returned by the LDAP server which is converted into a string representation which is returned to the caller.
2013-05-27IPA: Always initialize ID mappingSumit Bose1-4/+10
Because we now always want to store SIDs in the IPA provider, we also need to always initialize the ID mapping context.
2013-05-23Adding option to disable retrieving large AD groups.Lukas Slebodnik8-13/+51
This commit adds new option ldap_disable_range_retrieval with default value FALSE. If this option is enabled, large groups(>1500) will not be retrieved and behaviour will be similar like was before commit ae8d047122c "LDAP: Handle very large Active Directory groups" https://fedorahosted.org/sssd/ticket/1823
2013-05-23Removing unused functions.Lukas Slebodnik2-36/+0
This patch remove unused functions sdap_parse_user and sdap_parse_group
2013-05-22Fix return code for AD subdomain requestSumit Bose1-1/+3
2013-05-20Remove unneeded parameter of setup_child and namespace itJakub Hrozek5-5/+5
setup_child() was accepting a parameter it didn't use. Also the function name was too generic, so I added a sdap prefix.
2013-05-20Fixing critical format string issues.Lukas Slebodnik7-9/+15
--missing arguments. --format '%s', but argument is integer. --wrong format string, examle: '%\n'
2013-05-15Fix segfault in AD Subdomains ModuleLukas Slebodnik1-0/+2
In function ad_subdomains_get_netlogon_done: If variable "reply_count" is zero then variable "reply" will not be initialized. Therefore we should not continue.
2013-05-14Fix segfault in DYNDNSOndrej Kos1-1/+1
Added missing variable in DEBUG macro call.
2013-05-14Always update cached upn if enterprise principals are usedSumit Bose1-3/+4
Instead of continuing to use the initial upn if enterprise principals are used if should always be replaced. The enterprise principal is stored in the credential cache and without knowing it the ccache_for_princ() calls to determine the location of the credential cache will fail. Fixes https://fedorahosted.org/sssd/ticket/1921
2013-05-14Fix broken build with selinux.Lukas Slebodnik2-2/+4
Header file selinux/selinux.h was removed in commit 245cc346 from file ipa_selinux.c, because it breaks build without selinux. But new error was introduced. This patch fixes compilation with selinux and include header file selinux/selinux.h only if both macros exist HAVE_SELINUX and HAVE_SELINUX_LOGIN_DIR. Now ipa_selinux.c should be correctly built with and without selinux.
2013-05-13Re-add a useful DEBUG messageJakub Hrozek1-0/+2
In commit 46222e5191473f9a46aec581273eb2eef22e23be we removed a very similar DEBUG message while moving the whole piece of code to the idmap library. But it turned out that the DEBUG message was useful while testing the functionality, so this patch adds it back.
2013-05-13Fixes compilation without selinux.Lukas Slebodnik1-1/+0
Compilation fail if ./configure is called with arguments --with-selinux --with-semanage and selinux header files are not installed. We didn't not catch this in fedora, because krb5-devel depends on libselinux-devel, but other distribution can package it differently. And API from selinux.h is not used in file ipa_selinux.c
2013-05-13LDAP: Always initialize idmap objectJakub Hrozek1-5/+3
https://fedorahosted.org/sssd/ticket/1922 Since we always store the SID now, we need to always initialize the ID mapping object in LDAP provider as well. Some users might want to configure the LDAP provider with ID mapping, not the AD provider itself.
2013-05-13Enable the AD dynamic DNS updates by defaultJakub Hrozek1-1/+1
https://fedorahosted.org/sssd/ticket/1915
2013-05-07AD: read flat name and SID of the AD domainSumit Bose3-0/+590
For various features either the flat/short/NetBIOS domain name or the domain SID is needed. Since the responders already try to do a subdomain lookup when and known domain name is encountered I added a subdomain lookup to the AD provider which currently only reads the SID from the base DN and the NetBIOS name from a reply of a LDAP ping. The results are written to the cache to have them available even if SSSD is started in offline mode. Looking up trusted domains can be added later. Since all the needed responder code is already available from the corresponding work for the IPA provider this patch fixes https://fedorahosted.org/sssd/ticket/1468
2013-05-03Only check UPN if enterprise principals are not usedJakub Hrozek1-0/+5
If enterprise principals are enabled (which is the default in the AD provider), then the returned UPN might be slightly different from the one SSSD constructs before attempting the login. This patch makes SSSD only check if the principal is the same when the enterprise principals are disabled.
2013-05-03AD: Always initialize ID mappingJakub Hrozek1-5/+3
Because we now always store SIDs in the LDAP provider, we also need to always initialize the ID mapping context even if ID mapping itself is off.
2013-05-03Active Directory dynamic DNS updatesJakub Hrozek5-0/+306
https://fedorahosted.org/sssd/ticket/1504 Implements dynamic DNS updates for the AD provider. By default, the updates also update the reverse zone and run periodically every 24 hours.
2013-05-03Split out the common code from timed DNS updatesJakub Hrozek3-60/+133
2013-05-03dyndns: new option dyndns_authJakub Hrozek6-21/+93
This options is mostly provided for future expansion. Currently it is undocumented and both IPA and AD dynamic DNS updates default to GSS-TSIG. Allowed values are GSS-TSIG and none.
2013-05-03dyndns: new option dyndns_force_tcpJakub Hrozek4-6/+25
https://fedorahosted.org/sssd/ticket/1831 Adds a new option that can be used to force nsupdate to only use TCP to communicate with the DNS server.
