\fB/etc/suauth\fR
.SH "BESKRIVNING"
.PP
The file
/etc/suauth
is referenced whenever the su command is called\&. It can change the behaviour of the su command, based upon:
.sp
.if n \{\
.RS 4
.\}
.nf
1) the user su is targetting
.fi
.if n \{\
.RE
.\}
.PP
2) the user executing the su command (or any groups he might be a member of)
.PP
Filen \(:ar i f\(:oljande format, med de rader som inleds med # behandlas som kommentarsrader och ignoreras;
.sp
.if n \{\
.RS 4
.\}
.nf
till\-id:fr\(oan\-id:\(oATG\(:ARD
.fi
.if n \{\
.RE
.\}
.PP
Where to\-id is either the word
\fIALL\fR, a list of usernames delimited by "," or the words
\fIALL EXCEPT\fR
followed by a list of usernames delimited by ","\&.
.PP
fr\(oan\-id \(:ar formaterad p\(oa samma s\(:att som till\-id f\(:orutom att det extra ordet
\fIGROUP\fR
k\(:anns igen\&.
\fIALL EXCEPT GROUP\fR

\fIGROUP\fR
kan vara ett eller flera gruppnamn, separerade med ","\&. Det \(:ar inte tillr\(:ackligt att ha prim\(:art grupp\-id f\(:or den relevanta gruppen, en post i
\fB/etc/group\fR(5)
\(:ar n\(:odv\(:andigt\&.
.PP
\(oAtg\(:arden kan endast vara en av f\(:oljande f\(:or n\(:arvarande st\(:odda flaggor\&.
.PP

.RS 4
F\(:or att su\-kommandot ska lyckas m\(oaste anv\(:andaren mata in sitt egna l\(:osenord\&. De blir fr\(oagade att g\(:ora detta\&.
.RE
.PP
Note there are three separate fields delimited by a colon\&. No whitespace must surround this colon\&. Also note that the file is examined sequentially line by line, and the first applicable rule is used without examining the file further\&. This makes it possible for a system administrator to exercise as fine control as he or she wishes\&.
.SH "EXEMPEL"
.sp
.if n \{\
.RS 4

.nf
# exempelfil f\(:or /etc/suauth

# Alla andra kan inte su till root om de inte finns
# gruppen wheel\&. Det \(:ar s\(oa BSD g\(:or saker\&.
#

#
# Kanske terry och birddog \(:ar konton som

.SH "FEL"
.PP
There could be plenty lurking\&. The file parser is particularly unforgiving about syntax errors, expecting no spurious whitespace (apart from beginning and end of lines), and a specific token delimiting different things\&.
.SH "DIAGNOSTIK"
.PP
An error parsing the file is reported using
\fBsyslogd\fR(8)
as level ERR on facility AUTH\&.
.SH "SE OCKS\(oA"
.PP
\fBsu\fR(1)\&.
