* nss: use negative cache for sid-by-id requestsreview-negcacheSumit Bose2015-07-271-0/+55
| | | | | | | | | | | | | | | | | Since requests by ID are not assized to a specific domain SSSD might check the ID in domains where the ID does not exists even if the ID is already in the sysdb cache of the right domain. For requests where already a memory cache is available like e.g. getpwuid() and getgrgid() this has no negative impact because the requests are answered directly from the cache most of the time without hitting SSSD. As long as there is no use-case which does not use the memory cache those requests do not need an update. But for request like sid-by-id where currently no memory cache is available there are quite some additional costs especially for trusted domains. Resolves https://fedorahosted.org/sssd/ticket/2731

* nss_check_name_of_well_known_sid() improve name splittingSumit Bose2015-07-161-0/+8
| | | | | | | | | | | | | | | Currently in the default configuration nss_check_name_of_well_known_sid() can only split fully-qualified names in the user@domain.name style. DOM\user style names will cause an error and terminate the whole request. With this patch both styles can be handled by default, additionally if the name could not be split nss_check_name_of_well_known_sid() returns ENOENT which can be handled more gracefully by the caller.

* NSS: check for overrides before calling backendSumit Bose2015-05-061-5/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the flag that the input data in a user or group lookup request might be an override value is only set if no cached entry was found. If the cached entry of an object with overrides is expired and a request with the override value as input is processed the flag is not set and the backend might not be able to find the right entry on the server. Typically this should not happen because of mid-point refreshes. To reproduce this create a FreeIPA user and override the login name for a specific view. On a client which has this view applied call getent passwd overridename sss_cache -E getent passwd overridename The second getent command will still show the right output but in the logs a [sss_dp_get_reply] (0x1000): Got reply from Data Provider - DP error code: 3 errno: 0 error message: Account info lookup failed message can be found for the second request.

| | | | | | | | | | | | | | | | | | | | | | | | | | About case_sensitive=preserving and services. The name of the service can be preserved in result of 'getent service'. However we should still lowercase the protocol and service aliases because they serve as keys in some queries to sysdb. The lowercasing is done by the provider already. If we did not do that, we would lose case insesnsitivity. With this patch the responder preserves the case of service name and protocol, to match the case that is stored in the sysdb (however the protocol is already lowercased by provider, so it was done only for consistent use of the case_sensitive=preserve option in the responders and only the case of name is the same as in ldap).

| | | | | | | | | | | | | | | | | | | If we query group from subdomain it can contain users from different domains. All members from subdomain have fully qualified name, but member from main domain aren't. In function fill_members, we extracted name and domain with function fill_members. Later, we called function sss_fqname the first time with queried group domain and the second time with parsed domain. It caused following error in nss responder: [fill_members] (0x0040): Failed to generate a fully qualified name for member [user2_dom1@sssdad_tree.com] of group [group2_dom2@sssdad_tree.com]! Skipping The test test_nss_getgrnam_mix_dom_fqdn passed, because name of main domain and name of subdomain had the same length, Therefore there was not problem in function fill_members with calling sss_fqname with different domains.

* PAM, NSS: allow UPN login namesSumit Bose2014-09-012-7/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | With this patch the NSS and PAM responders can handle user principal names besides the fully qualified user names. User principal names are build from a user name and a domain suffix separated by an '@' sign. But the domain suffix does not necessarily has to be the same as the configured domain name in sssd.conf of the dynamically discovered DNS domain name of a domain. The typical use case is an Active Directory forest with lots of different domains. To not force the users to remember the name of the individual domain they belong to the AD administrator can set a common domain suffix for all users from all domains in the forest. This is typically the domain name used for emails to make it even more easy to the users to remember it. Since SSSD splits name and domain part at the '@' sign and the common domain suffix might not be resolvable by DNS or the given user is not a member of that domain (e.g. in the case where the forest root is used as common domain suffix) SSSD might fail to look up the user. With this patch the NSS and PAM responder will do an extra lookup for a UPN if the domain part of the given name is not known or the user was not found and the login name contained the '@' sign.
