2013-08-26sudo: do not strdup usn on ENOENTPavel Březina1-1/+1
If USN attribute is not present, we call strdup on uninitialized variable. This may cause segfault, or if we are lucky and usn is NULL it will return ENOMEM.
2013-08-26sudo: do not fail to store the rule if we can't read usnPavel Březina1-3/+4
Resolves: https://fedorahosted.org/sssd/ticket/2052
2013-08-19sysdb_add_incomplete_group: store SID string is availableSumit Bose2-9/+18
During initgroups request we read the SID of a group from the server but do not save it to the cache. This patch fixes this and might help to avoid an additional lookup of the SID later.
2013-08-19save_rfc2307bis_user_memberships: use fq names for subdomainsSumit Bose1-0/+16
For subdomains the group names must be expanded to fully qualified names to be able to find existing groups or properly add new ones.
2013-08-19sdap_add_incomplete_groups: use fully qualified name if neededSumit Bose1-4/+14
For subdomains the group names must be expanded to fully qualified names to be able to find existing groups or properly add new ones.

2013-08-19sdap_save_user: save original primary GID of subdomain usersSumit Bose1-11/+22
If ID mapping is enabled we use magic private groups (MPG) for subdomains, i.e. the UID and the primary GID of the user will have the same numerical value. As a consequence the information about the original primary group might get lost because neither in AD domains nor on a typical UNIX system the user is an explicit member of it's primary group. With this patch the mapped GID or the original primary group is saved in the cached user object under a new attribute. Fixes https://fedorahosted.org/sssd/ticket/2027
2013-08-19sdap_get_initgr_done: use the right SID to get a GIDSumit Bose1-1/+2
2013-08-11ldap, krb5: More descriptive msg on chpass failure.Michal Zidek1-0/+15
Print more descriptive message when wrong current password is given during password change operation. resolves: https://fedorahosted.org/sssd/ticket/2029
2013-08-08Enable removing nonexisting dn in sdap_handle_account_infoLukas Slebodnik1-1/+1
Change was introduced in commit ca344fde
2013-08-08Fix memory context for hash entriesSumit Bose1-2/+4
In sdap_nested_group_populate_users() username and orignal_dn are allocated on a temporary memory context. If the corresponding user is not found in the cache both are added to a hash which is later on returned to the caller. To avoid a use-after-free when the hash entries are looked up both must be reassigned to the memory context of the hash.
2013-08-07Fix memory context for a state memberSumit Bose1-1/+1
primary_name was allocated on a temporary memory context but as it is a member of the state struct it should belong to the memory context of the state.

2013-07-24LDAP: Use domain-specific name where appropriateJakub Hrozek5-112/+159
The subdomain users user FQDN in their name attribute. However, handling of whether to use FQDN in the LDAP code was not really good. This patch introduces a utility function and converts code that was relying on user/group names matching to this utility function. This is a temporary fix until we can refactor the sysdb API in #2011.

2013-07-17LDAP: When resolving a SID, search for groups first, then usersJakub Hrozek1-19/+18
https://fedorahosted.org/sssd/ticket/1997 Most of the time, the SIDs are resolved as a call coming from the PAC responder during initgroups. In that case at least, it makes sense to search for group matching that SID first, then users. We may consider making this behaviour configurable ie for the server mode where typically the users should be queried first.
2013-07-01ldap: only update shadowLastChange when password change is successfulJim Collins1-1/+2
https://fedorahosted.org/sssd/ticket/1999 ldap_auth.c code which was added to SSSD for updating the shadowLastChange when "ldap_chpass_update_last_change" option is enabled updates shadowLastChange even when the PAM password change status reports failure. We should only update shadowLastChange on PAM password change success or we open up a work around for users to avoid changing their passwords periodically as required by policy. The user simply attempts to change password, fails by trying to set new password which invalid (denied due to password history check) yet shadowLastChange is updated, avoiding their need to actually change the password they are using.
2013-06-28AD: Move storing sdap_domain for subdomain to generic LDAP codeJakub Hrozek2-0/+77
Makes creating the sdap_domain structure for a subdomain reusable outside AD subdomain code where it was created initially. Subtask of: https://fedorahosted.org/sssd/ticket/1962
2013-06-28LDAP: Add utility function sdap_copy_mapJakub Hrozek2-0/+45
The AD subdomains will only use default options values. This patch introduces a new utility function sdap_copy_map() that copies the default options map. Subtask of: https://fedorahosted.org/sssd/ticket/1962
2013-06-28Replace new_subdomain() with find_subdomain_by_name()Sumit Bose1-3/+2
new_subdomain() will create a new domain object and should not be used anymore in the priovder code directly. Instead a reference to the domain from the common domain object should be used.
2013-06-28Replace SDAP_ID_MAPPING checks with sdap_idmap_domain_has_algorithmic_mappingSumit Bose5-14/+38
Currently the decision if external or algorithmic mapping should be used in the LDAP or AD provider was based on the value of the ldap_id_mapping config option. Since now all information about ID mapping is handled by libsss_idmap the check for this options can be replace with a call which checks the state via libss_idmap. https://fedorahosted.org/sssd/ticket/1961
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.

2013-06-10A 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.

2013-05-27Fail 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.
