* LDAP: Filter out multiple entries when searching overlapping domainsJakub Hrozek2015-09-221-11/+24
| | | | | | | | | | In case domain overlap, we might download multiple objects. To avoid saving them all, we attempt to filter out the objects from foreign domains. We can only do this optimization for non-wildcard lookups. Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>
* LDAP: imposing sizelimit=1 for single-entry searches breaks overlapping domainsJakub Hrozek2015-09-221-3/+0
| | | | | | | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2723 In case there are overlapping sdap domains, a search for a single user might match and return multiple entries. For instance, with AD domains represented by search bases: DC=win,DC=trust,DC=test DC=child,DC=win,DC=trust,DC=test A search for user from win.trust.test would be based at: DC=win,DC=trust,DC=test but would match both search bases and return both users. Instead of performing complex filtering, just save both users. The responder would select the entry that matches the user's search. Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>

* SDAP: Set initgroups expire attribute at the endLukas Slebodnik2015-05-221-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Initgrups consisted of two main steps: 1. store user to cache 2. store all user groups to cache. Previously the attribute SYSDB_INITGR_EXPIRE was set in the first step. So in case of epmty cache and parallel initgroups request in responders there was a small period when SYSDB_INITGR_EXPIRE was valid but groups were not cached. Therefore sometime responder could return zero supplementary groups. This patch moves the setting of initgroups expire attribute from 1st step to the end of 2nd step. In case of parallel initgroups requests in responder there are two other ways how we could get correct results even thought there was a bug. a) Time between two request was too small. User was not stored in cache yet and 2nd request waited for response from DP. b) Time between two request was big enough. All users groups were successfully stored in cache and 2nd request returned correct results. Resolves: https://fedorahosted.org/sssd/ticket/2634 Reviewed-by: Pavel Březina <pbrezina@redhat.com>
* sdap: properly handle binary objectGuid attributeSumit Bose2015-03-201-16/+7
| | | | | | | | | | | | | | Although in the initial processing SSSD treats the binary value right at some point it mainly assumes that it is a string. Depending on the value this might end up with the correct binary value stored in the cache but in most cases there will be only a broken entry in the cache. This patch converts the binary value into a string representation which is described in [MS-DTYP] and stores the result in the cache.

| | | | | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2073 This commit adds a new option ldap_user_extra_attrs that is unset by default. When set, the option contains a list of LDAP attributes the LDAP provider would download and store in addition to the usual set. The list can either contain LDAP attribute names only, or colon-separated tuples of LDAP attribute and SSSD cache attribute name. In case only LDAP attribute name is specified, the attribute is saved to the cache verbatim. Using a custom SSSD attribute name might be required by environments that configure several SSSD domains with different LDAP schemas.

| | | | | | | | | | Related: https://fedorahosted.org/sssd/ticket/2077 Certain situations require that a user entry is downloaded for further inpection, but not saved to the sysdb right away. This patch splits the previously monolithic request into one that just downloads the data and one that uses the new one to download and save the user.

* sdap_save_user: try to determine domain by SIDPavel Březina2013-10-291-22/+32
| | | | | | | | | | | | | GC contains objects from both parent domain and subdomain. Lets say we have user with UID 5000 that belongs to a subdomain and overlapping search bases dc=ad,dc=pb and dc=sub,dc=ad,dc=pb. Now we call 'getent passwd 5000' and this request goes through data provider, searching in parent domain first. Even though this user does not belong to this domain it is found and stored as ad.pb user. With this patch we look at user's SID and put it into correct domain.
* sdap_idmap_domain_has_algorithmic_mapping: add domain name argumentSumit Bose2013-10-251-0/+1
| | | | | | | | | | | | | When libss_idmap was only used to algorithmically map a SID to a POSIX ID a domain SID was strictly necessary and the only information needed to find a domain. With the introduction of external mappings there are cases where a domain SID is not available. Currently we relied on the fact that external mapping was always used as a default if not specific information about the domain was found. The lead to extra CPU cycles and potentially confusing debug messages. Adding the domain name as a search parameter will avoid this.

* sdap_save_user: save original primary GID of subdomain usersSumit Bose2013-08-191-11/+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
* LDAP: Use domain-specific name where appropriateJakub Hrozek2013-07-241-42/+39
| | | | | | | | | 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.
* Replace SDAP_ID_MAPPING checks with sdap_idmap_domain_has_algorithmic_mappingSumit Bose2013-06-281-1/+4
| | | | | | | | | | 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
* LDAP: Do not store separate GID for subdomain usersJakub Hrozek2013-06-071-10/+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.
* Split generating primary GID for ID mapped users into a separate functionJakub Hrozek2013-06-071-41/+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.
* LDAP: store FQDNs for trusted users and groupsJakub Hrozek2013-06-071-2/+10
| | | | | | 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.
* LDAP: always store SID if availableSumit Bose2013-05-021-12/+30
| | | | | | | 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.

| | | | | | | The code would call sysdb_attrs_add_uint32 which added another UID or GID to the ID=0 we already downloaded from LDAP (0 is the default value) when ID-mapping an entry. This led to funky behaviour later on when we wanted to process the ID.

* LDAP: Only convert direct parents' ghost attribute to memberJakub Hrozek2012-11-201-5/+17
| | | | | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1612 This patch changes the handling of ghost attributes when saving the actual user entry. Instead of always linking all groups that contained the ghost attribute with the new user entry, the original member attributes are now saved in the group object and the user entry is only linked with its direct parents. As the member attribute is compared against the originalDN of the user, if either the originalDN or the originalMember attributes are missing, the user object is linked with all the groups as a fallback. The original member attributes are only saved if the LDAP schema supports nesting.
