-.TH NSS 5 2013-02-13 "Linux" "Linux Programmer's Manual"
-.SH NAME
-nss \- Name Service Switch configuration file
-.SH DESCRIPTION
-Each call to a function which retrieves data from a system database
-like the password or group database is handled by the Name Service
-Switch implementation in the GNU C library.
-The various services
-provided are implemented by independent modules, each of which
-naturally varies widely from the other.
-.PP
-The default implementations coming with the GNU C library are by
-default conservative and do not use unsafe data.
-This might be very costly in some situations, especially when the databases
-are large.
-Some modules allow the system administrator to request
-taking shortcuts if these are known to be safe.
-It is then the system administrator's responsibility to ensure the assumption
-is correct.
-.PP
-There are other modules where the implementation changed over time.
-If an implementation used to sacrifice speed for memory consumption,
-it might create problems if the preference is switched.
-.PP
-The
-.I /etc/default/nss
-file contains a number of variable assignments.
-Each variable controls the behavior of one or more
-NSS modules.
-White spaces are ignored.
-Lines beginning with \(aq#\(aq
-are treated as comments.
-.PP
-The variables currently recognized are:
-.TP
-\fBNETID_AUTHORITATIVE =\fR \fITRUE\fR|\fIFALSE\fR
-If set to TRUE, the NIS backend for the
-.BR initgroups (3)
-function will accept the information
-from the
-.I netid.byname
-NIS map as authoritative.
-This can speed up the function significantly if the
-.I group.byname
-map is large.
-The content of the
-.I netid.byname
-map is used \fBas is\fR.
-The system administrator has to make sure it is correctly generated.
-.TP
-\fBSERVICES_AUTHORITATIVE =\fR \fITRUE\fR|\fIFALSE\fR
-If set to TRUE, the NIS backend for the
-.BR getservbyname (3)
-and
-.BR getservbyname_r (3)
-functions will assume that the
-.I services.byservicename
-NIS map exists and is authoritative, particularly
-that it contains both keys with /proto and without /proto for both
-primary service names and service aliases.
-The system administrator has to make sure it is correctly generated.
-.TP
-\fBSETENT_BATCH_READ =\fR \fITRUE\fR|\fIFALSE\fR
-If set to TRUE, the NIS backend for the
-.BR setpwent (3)
-and
-.BR setgrent (3)
-functions will read the entire database at once and then
-hand out the requests one by one from memory with every corresponding
-.BR getpwent (3)
-or
-.BR getgrent (3)
-call respectively.
-Otherwise, each
-.BR getpwent (3)
-or
-.BR getgrent (3)
-call might result in a network communication with the server to get
-the next entry.
-.SH FILES
-\fI/etc/default/nss\fR
-.SH EXAMPLE
-The default configuration corresponds to the following configuration file:
-
-.nf
-NETID_AUTHORITATIVE=FALSE
-SERVICES_AUTHORITATIVE=FALSE
-SETENT_BATCH_READ=FALSE
