* LDAP: Drop privileges after kinit in ldap_childJakub Hrozek2014-11-052-34/+64
| | | | | | | | After ldap_child initializes privileges using root-owned keytab, it drops privileges to the SSSD user, minimizing the amount of code that runs as root. Reviewed-by: Michal Židek <mzidek@redhat.com>
* LDAP: read the correct data type from ldap_child's input bufferJakub Hrozek2014-11-051-2/+2

* LDAP: Move sss_krb5_verify_keytab_ex to ldap_childJakub Hrozek2014-11-051-1/+78
| | | | | | | | The function was called from one place only, so it makes no sense to keep it in a shared module. Moreover, the function should only be called from code that runs as root. Reviewed-by: Michal Židek <mzidek@redhat.com>
* Views: apply user SSH public key overrideSumit Bose2014-11-052-0/+2
| | | | | | | | | | | | | With this patch the SSH public key override attribute is read from the FreeIPA server and saved in the cache with the other override data. Since it is possible to have multiple public SSH keys this override value does not replace any other data but will be added to existing values.

* IPA: inherit ldap_user_extra_attrs to AD subdomainsSumit Bose2014-11-051-0/+31
| | | | | | | | | | | | | | Currently the component of the IPA provider which reads the AD user and group attributes in ipa-server-mode uses default settings for the LDAP related attributes. As a result even if ldap_user_extra_attrs is defined in sssd.conf no extra attributes are read from AD. With the patch the value if ldap_user_extra_attrs is inherited to the AD subdomains to allow them to read extra attributes as well.

* IPA: use ipaUserGroup object class for groupsPavel Březina2014-11-051-1/+1
| | | | | | | | | | | | | dfb34c6c82ed5014599bf70de6791e6d79106fc2 changed object class of IPA groups from posixGroups to more general groupOfNames. However, this object class is used also for roles, permissions and privileges which caused SSSD to consider those objects to be groups as well during initgroups.

* views: search overrides for user and group requestsSumit Bose2014-10-166-101/+602
| | | | | | | | | | | | | | | | | | | | | | | | | If the name or the POSIX ID of a user or a group is overridden the search request for those objects have to check the overide objects first before looking up the original objects. This patch adds a new request for the IPA sub-domain users which checks the overrides first if - SSSD is running in ipa-server-mode and a name or a POSIX ID is searched, since we do not override the SIDs we can skip the search in the override tree here - if the responder indicates it has not found the corresponding object in the cache and the input might be an override name or ID and not the original one of an object. If an override object was found the SID is extracted from the anchor attribute and the original object is search by its SID. If no override object was found the original object is search with the original input and finally it is checked if an override object exits for the found object.

In ipa-server-mode the default view is automatically applied and written to the cache. On IPA clients which use the extdom plugin for user and group lookups the override data is saved separately and the original object and the override data are linked with DN attributes for faster reference.

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.

In this case the rootDSE lookup in SSSD will terminate the connection to the server and return a error.

| | | | | | | | | | | | | | | | | | | Initially the extdom plugin was only used to translate SIDs of AD user and groups to names or POSIX IDs. On IPA clients group memberships were resolved with the help of the PAC in the Kerberos ticket which required that the user has logged in at least once. Home directory and the login shell were auto generated. The new version of the extdom plugin can return the complete list of group memberships of a user and the list of all members of a group. Additionally the gecos field, home directory and login shell are returned together with an optional list of key-value pairs for arbitrary data which is written unmodified to the cache.
