* IFP: Use the override_space optionJakub Hrozek2014-08-131-2/+51
| | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2397 The input of the InfoPipe responder substitutes the configured character for space and the GetUserAttrs and GetUserGroups functions substitute space for the configured character in their output.

* NSS: Ignore default_domain for netgroupsJakub Hrozek2014-08-121-1/+1
| | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/2400 Netgroups often have members that will not process correctly when we require a fully-qualified name. This patch simply ignores the default_domain setting for netgroup lookups - we ignore FQDN only domains for netgroup lookups since 1933ff17513da1d979dd22776a03478341ef5e6b anyway.

| | | | | | | | | | | | | The Data Provider lookup code user the original input string as the lookup key instead of the parsed name component. For example, for an input joe@mydomain, the backend would have searched for: (&(cn=joe@mydomain)(objectclass=user)) This patch fixes the lookup to use the parsed name. https://fedorahosted.org/sssd/ticket/2402 Reviewed-by: Pavel Březina <pbrezina@redhat.com>

| | | | | | | | | | | | | | | | | | This attribute was used in pre 1.7 versions of sudo and it is now deprecated by sudoRunAsUser and sudoRunAsGroup. However, some users still use this attribute so we need to support it to ensure backward compatibility. This patch makes sure that this attribute is downloaded if present and provided to sudo. Sudo than decides how to handle it. The new mapping option is not present in a man page since this attribute is deprecated in sudo for a very long time.

* IFP: Add GetUserAttrs callJakub Hrozek2014-05-136-0/+597
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a DBus method that allows the caller to retrieve attributes of a user. The synopsis of the call is as follows: <method name="GetUserAttr"> <arg type="s" name="user" direction="in"/> <arg type="as" name="attr" direction="in"/> <arg type="a{sv}" name="values" direction="out"/> </method> The return value is an array (one attribute per array member) of dictionaries. The key of the dictionary is the attribute name, the value is a variant containing the attribute values as strings. If an attribute does not exist or is not permitted to be read, no error is returned. If the users does not exist, the method returns an error. In future patches this function will be marked as obsolete in favor of object-oriented approach. ifp_user_get_attr_unpack_msg is a separate function to allow extending it in a later patch. The function to check the cache validity duplicates quite a bit of code with the NSS responder. The refactoring would be nice to get done along with #843.

* IFP: Initialize negative cache timeoutJakub Hrozek2014-05-132-0/+17
| | | | | | | | | | | | | | In order to avoid hitting the back end with repetitive requests, the InfoPipe responder needs a negative cache, too. This patch follows the convention set by other responders, where the negative cache timeouts are read from the [nss] section. This is not ideal, however, and ticket #2318 tracks moving the configuration to the [ifp] section primarily. The timeout is also a separate parameter in the NSS context. We should consider moving it to the negcache context instead (#2317). Reviewed-by: Pavel Březina <pbrezina@redhat.com> Reviewed-by: Stef Walter <stefw@redhat.com>

* DP: Remove unused 'force' parameter from the subdomain handlerJakub Hrozek2014-04-221-14/+4
| | | | | | | | | | | | | The force argument was unused and made the code more complex than required. Moreover, the force argument would have made the subdomain handler behave differently than other identity domains -- when the front end decides it's time to update the domains, the back end should just update them. Handling multiple concurrent requests from multiple responders (typically after startup) is handled at the generic back end level (see be_queue_request).

* sbus: Add type-safe DBus method handlers and finish functionsStef Walter2014-04-193-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Type safe method handlers allow methods not to have to do tedious unwrapping and wrapping of DBus method call messages or replies. Arguments of the following DBus types are supported in type-safe method handlers. In addition arrays of these are supported. y: uint8_t b: bool (but no arrays, yet) n: int16_t q: uint16_t i: int32_t u: uint32_t x: int64_t t: uint64_t d: double s: char * (utf8 string) o: char * (object path) As an exception, arrays of booleans are not supported, but could be added later. Other more complex types could be added later if desired. If a method has other argument types, then it must be marked as having a raw handler (see below). Internally each method can have a type specific invoker function which unpacks the incoming arguments and invokes the method handler with the correct arguments. Each method also has a finish which accepts the type-safe out arguments (ie: return values) and builds the reply message. Like other request 'finish' functions, these free the request talloc context, and are to be used in place of sbus_request_finish() or friends. Raw method handlers parse their own method arguments, and prepare their own reply (ideally using sbus_request_finish() helpers). They can also do strange things like have variable arguments. To mark a DBus method as having a raw method handler use the following annotation: <annotation name="org.freedesktop.sssd.RawHandler" value="true"/> Raw methods do not have invokers or finish functions. I've left all of the internal peer to peer communication using raw method handlers. No code changes here.
