* nss: add SSS_NSS_GETORIGBYNAME requestSumit Bose2014-10-141-2/+89
| | | | | | | | | | | | | | | This patch adds a new request to the nss responder which follows the same flow as a SSS_NSSGETSIDBYNAME request but returns more data than just the SID. The data is returned as pairs of \0-terminated strings where the first string is the sysdb attribute name and the second the corresponding value. The main use case is on the FreeIPA server to make additional user and group data available to the extdom plugin which then send this data to SSSD running on FreeIPA clients.

* name2sid: Check negative cache for users and groupsSumit Bose2014-09-161-15/+19
| | | | | | | | | | | | Since we cannot know if a SID belongs to a user or a group a lookup should only fail if the given name is in both the negative cache for the users and the groups. Currently if the SID for a group called 'abc' should be looked up and the negative cache for the users contain an entry for 'abc' the request fails. Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>
* NSS: Use right domain for group members with fq namesLukas Slebodnik2014-09-051-1/+2
| | | | | | | | | | | | | | | | | | | 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. This patch also changes name of subdomain to prevent such problems in future. Reviewed-by: Pavel Reichl <preichl@redhat.com>
* PAM, NSS: allow UPN login namesSumit Bose2014-09-011-7/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* NSS: Don't use printf(3) on user provided strings.Stef Walter2014-01-121-87/+45
| | | | | | | | | | | | | | | | | | | | This also fixes several corner cases and crashers. It's not prudent to pass user input to (even admin) input as a format string to printf, and various distros now check for this. This can cause accessing memory incorrectly, and various also various libc abort()'s. In addition various assumptions were made about full_name_format that aren't necessarily the case if the user uses a more complex format. Use safe-printf.c implementation for formatting full_name_format. Adapt the NSS resolver so it doesn't barf on formatted strings that are shorter than expected given a full_name_format. Tests added and updated appropriately.

* NSS: Print FQDN for groups with mixed domain membershipJakub Hrozek2013-10-291-9/+64
| | | | | | | | | | | | | | | | | This patch is a workaround until https://fedorahosted.org/sssd/ticket/2129 is fixed properly. Consider a group entry such as: cn: subgroup@subdom ghost: someuser ghost: anotheruser@subdom Currently in order to print all group members as FQDN (which is the default for AD provider), the code needs to iterate over the ghost attributes and parse them into (name,domain) and optionally re-add the domain. The proper fix would be to store always just the FQDN in the hardcoded form of user@domain
* nss: wait for initial subdomains request to finishPavel Březina2013-10-171-0/+14
| | | | | | | | | | | | AD provider downloads domain information and initalizes ID mapping during subdomains request. This information is necessary to lookup objects without POSIX attributes.
