LDAP: Augment the sdap_opts structure with a data provider pointer In order to be able to use the Data Provider methods from the SDAP code to e.g. invalidate memcache when needed, add a new field to the sdap_options structure with the data_provider structure pointer.

providers: Move hostid from ipa to sdap, v2 In the ldap provider, all option names are renamed to ldap_host_*. In the ipa provider the names haven't been changed.

DP: Create a new handler function getAccountDomain() Adds a new method getAccountDomain() which is a bit similar to getAccountInfo, except it doesn't fetch, parse and store the entry, but just returns the domain or a subdomain the entry was found in. At the moment, the method only supports requests by ID. A default handler is provided (and in this patch used by all the domains) which returns ERR_GET_ACCT_DOM_NOT_SUPPORTED. This return code should be evaluated by the responder so that this DP method is not called again, because it's not supported by the back end type.

SDAP: account lockout to restrict access via ssh key Be able to configure sssd to honor openldap account lock to restrict access via ssh key. Introduce new ldap_access_order value ('lock') for enabling/disabling this feature. Account is considered locked if pwdAccountLockedTime attribut has value of 000001010000Z. ------------------------------------------------------------------------ Quotation from man slapo-ppolicy: pwdAccountLockedTime This attribute contains the time that the user's account was locked. If the account has been locked, the password may no longer be used to authenticate the user to the directory. If pwdAccountLockedTime is set to 000001010000Z, the user's account has been permanently locked and may only be unlocked by an administrator.

AD: Use the ad_access_filter if it's set Related: https://fedorahosted.org/sssd/ticket/2082 Currently the AD access control only checks if an account has been expired. This patch amends the logic so that if ad_access_filter is set, it is used automatically.

LDAP: Make sdap_id_setup_tasks reusable for subdomains Instead of always performing the setup for the main domain, the setup can now be performed for subdomains as well.

providers: refresh expired netgroups https://fedorahosted.org/sssd/ticket/1713

LDAP: new SDAP domain structure 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.

LDAP: sdap_id_ctx might contain several connections 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.

Remove unneeded parameter of setup_child and namespace it setup_child() was accepting a parameter it didn't use. Also the function name was too generic, so I added a sdap prefix.

LDAP: Always initialize idmap object https://fedorahosted.org/sssd/ticket/1922 Since we always store the SID now, we need to always initialize the ID mapping object in LDAP provider as well. Some users might want to configure the LDAP provider with ID mapping, not the AD provider itself.

DNS sites support - use SRV DNS lookup plugin in all providers https://fedorahosted.org/sssd/ticket/1032 We set a plugin during an initialization of ID provider, which is an authoritative provider for a plugin choice. The plugin is set only once. When other provider is initalized (e.g. id = IPA, sudo = LDAP), we do not overwrite the plugin. Since sssm_*_id_init() is called from all module constructors, this patch relies on the fact, that ID provider is initialized before all other providers.

Make ID provider init functions clearer Using sssm_*_init() as the name of the initialization function for identity providers was a holdover from earlier development when we thought we would only have a single "provider" entry in the config file.
