.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 targeting
|
||
|
||
.fi
|
||
.if n \{\
|
||
.RE
|
||
.\}
|
||
.PP
|
||
2) 执行 su 命令的用户 (或者他可能属于的组)
|
||
.PP
|
||
文件格式为：以 # 开头的行视为注视，并被忽略；
|
||
.sp
|
||
.if n \{\
|
||
.RS 4
|
||
.\}
|
||
.nf
|
||
to\-id:from\-id:ACTION
|
||
|
||
.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
|
||
from\-id is formatted the same as to\-id except the extra word
|
||
\fIGROUP\fR
|
||
is recognized\&.
|
||
\fIALL EXCEPT GROUP\fR
|
||
is perfectly valid too\&. Following
|
||
\fIGROUP\fR
|
||
appears one or more group names, delimited by ","\&. It is not sufficient to have primary group id of the relevant group, an entry in
|
||
\fB/etc/group\fR(5)
|
||
is necessary\&.
|
||
.PP
|
||
动作只可以使用如下当前支持的选项。
|
||
.PP
|
||
\fIDENY\fR
|
||
.RS 4
|
||
su 的尝试在询问密码之前就被拒绝。
|
||
.RE
|
||
.PP
|
||
\fINOPASS\fR
|
||
.RS 4
|
||
su 尝试自动成功，而且不询问密码。
|
||
.RE
|
||
.PP
|
||
\fIOWNPASS\fR
|
||
.RS 4
|
||
为了成功执行 su，用户必须提供自己的密码。将会提示他们这样。
|
||
.RE
|
||
.PP
|
||
注意，有三个用冒号分割的字段。冒号旁边不能有空格。也请注意，这个文件会被一行一行地依次检查，会使用第一个可用的规则，而不会继续检查文件。这可以让系统管理员使系统尽量符合其期望。

可能会有很多潜在问题。文件解析器尤其不能容忍语法错误，不能有无意义的空白符(除了行首和行尾)，并且使用特定的标记分割不同的事情。

An error parsing the file is reported using
