sssd-ifp 5 File Formats and Conventions sssd-ifp SSSD InfoPipe responder This manual page describes the configuration of the InfoPipe responder for sssd 8 . For a detailed syntax reference, refer to the FILE FORMAT section of the sssd.conf 5 manual page. The InfoPipe responder provides a public D-Bus interface accessible over the system bus. The interface allows the user to query information about remote users and groups over the system bus. These options can be used to configure the InfoPipe responder. allowed_uids (string) Specifies the comma-separated list of UID values or user names that are allowed to access the InfoPipe responder. User names are resolved to UIDs at startup. Default: 0 (only the root user is allowed to access the InfoPipe responder) Please note that although the UID 0 is used as the default it will be overwritten with this option. If you still want to allow the root user to access the InfoPipe responder, which would be the typical case, you have to add 0 to the list of allowed UIDs as well. user_attributes (string) Specifies the comma-separated list of white or blacklisted attributes. By default, the InfoPipe responder only allows the default set of POSIX attributes to be requested. This set is the same as returned by getpwnam 3 and includes: name user's login name uidNumber user ID gidNumber primary group ID gecos user information, typically full name homeDirectory home directory loginShell user shell It is possible to add another attribute to this set by using +attr_name or explicitly remove an attribute using -attr_name. For example, to allow telephoneNumber but deny loginShell, you would use the following configuration: user_attributes = +telephoneNumber, -loginShell Default: not set. Only the default set of POSIX attributes is allowed.
