2013-06-28Add sdap_idmap_domain_has_algorithmic_mapping()Sumit Bose2-0/+62
This patch implements a wrapper for sss_idmap_domain_has_algorithmic_mapping() for the sdap ID mapping. Fixes https://fedorahosted.org/sssd/ticket/1960
2013-06-28Allow different methods to find new domains for idmappingSumit Bose2-3/+24
Currently the range management code is in the generic LDAP provider and can be used by the LDAP and AD provider. New ranges are allocated with the help of a hash value of the domain SID. If the IPA provider cannot find a range for a given domain it cannot allocate a new range on its own but has to look up the idrange objects on the FreeIPA server and use them accordingly. To allow the LDAP, AD and IPA provider to use as much common code as possible a plugin interface, similar to the one used to find the DNS site, to find a missing range would be useful. The default plugin will be used by the LDAP and the AD provider and the IPA provider will implement a plugin to read the data from the server. Fixes https://fedorahosted.org/sssd/ticket/1961
2013-06-28SDAP IDMAP: Add configured domain to idmap contextSumit Bose1-0/+70
To allow libsss_idmap to manage all id-ranges the id-ranges of the domains configured in sssd.conf which are currently unmanaged must be added to libsss_idmap.
2013-06-28Add now options ldap_min_id and ldap_max_idSumit Bose2-0/+4
Currently the range for Posix IDs stored in an LDAP server is unbound. This might lead to conflicts in a setup with AD and trusts when the configured domain uses IDs from LDAP. With the two noe options this conflict can be avoided.
2013-06-24LDAP: Retry SID search based on result of LDAP search, not the return codeJakub Hrozek1-2/+13
2013-06-18nested groups: do not expect any particular number of groupsPavel Březina1-19/+10
2013-06-18nested groups: do not return ENOMEM if num_groups is 0Pavel Březina1-6/+10
talloc_realloc(..., 0) calls talloc_free() and returns NULL. If we process group that contains only users, we errornously return ENOMEM.

2013-06-17nested groups: allocate more space if deref returns more membersPavel Březina1-0/+21
https://fedorahosted.org/sssd/ticket/1894
2013-06-10A new option krb5_use_kdcinfoJakub Hrozek3-2/+8
https://fedorahosted.org/sssd/ticket/1883 The patch introduces a new Kerberos provider option called krb5_use_kdcinfo. The option is true by default in all providers. When set to false, the SSSD will not create krb5 info files that the locator plugin consumes and the user would have to set up the Kerberos options manually in krb5.conf

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.
2013-06-07LDAP: 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 Hrozek21-127/+281
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 Hrozek6-29/+62
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 Hrozek13-73/+142
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 Hrozek1-10/+29
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.
2013-06-06Intermittent 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.

2013-05-28Remove unneeded commentJakub Hrozek1-1/+0
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.
2013-05-27Handle 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.
2013-05-23Adding option to disable retrieving large AD groups.Lukas Slebodnik6-13/+49
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
2013-05-20Remove unneeded parameter of setup_child and namespace itJakub Hrozek3-3/+3
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 Slebodnik5-6/+10
--missing arguments. --format '%s', but argument is integer. --wrong format string, examle: '%\n'
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.
2013-05-13LDAP: 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.
2013-05-03Split out the common code from timed DNS updatesJakub Hrozek2-0/+121
2013-05-03dyndns: new option dyndns_authJakub Hrozek2-2/+8
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 Hrozek1-2/+6
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.
2013-05-03dyndns: New option dyndns_update_ptrJakub Hrozek2-36/+160
https://fedorahosted.org/sssd/ticket/1832 While some servers, such as FreeIPA allow the PTR record to be synchronized when the forward record is updated, other servers, including Active Directory, require that the PTR record is synchronized manually. This patch adds a new option, dyndns_update_ptr that automatically generates appropriate DNS update message for updating the reverse zone. This option is off by default in the IPA provider. Also renames be_nsupdate_create_msg to be_nsupdate_create_fwd_msg
2013-05-03Refactor dynamic DNS updatesJakub Hrozek2-0/+545
Provides two new layers instead of the previous IPA specific layer: 1) dp_dyndns.c -- a very generic dyndns layer on the DP level. Its purpose it to make it possible for any back end to use dynamic DNS updates. 2) sdap_dyndns.c -- a wrapper around dp_dyndns.c that utilizes some LDAP-specific features like autodetecting the address from the LDAP connection. Also converts the dyndns code to new specific error codes.
2013-05-02Add secid filter to responder-dp protocolSumit Bose1-0/+6
This patch add a new filter type to the data-provider interface which can be used for SID-based lookups.
2013-05-02LDAP: always store SID if availableSumit Bose2-33/+58
Currently the string representation of a SID is only stored in the cache for debugging purpose if SID based ID-mapping is used. This patch unconditionally stores the SID if available to allow SID-to-name mappings from the cache.
2013-05-02sdap: add sdap_connect_host requestPavel Březina2-0/+201
Create connection to specified LDAP server without using any failover stuff.
2013-05-02Display the last grace warning, tooJakub Hrozek2-3/+3
Due to a comparison error, the last warning when an LDAP password was in its grace period was never displayed. https://fedorahosted.org/sssd/ticket/1890
2013-04-29libsss_idmap: function to calculate rangeMichal Zidek2-115/+54
Calculation of range for domains is moved from sdap_idmap code to sss_idmap code. Some refactoring have been done to allow this move. https://fedorahosted.org/sssd/ticket/1844
2013-04-19LDAP: do not invalidate pointer with realloc while processing ghost usersJakub Hrozek1-3/+13
https://fedorahosted.org/sssd/ticket/1799 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.
2013-04-10DNS sites support - use SRV DNS lookup plugin in all providersPavel Březina1-0/+9
https://fedorahosted.org/sssd/ticket/1032 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.

2013-04-02Making the authtok structure really opaque.Lukas Slebodnik2-9/+15
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
