.IX Header "DESCRIPTION"
In addition to the standard \fIsudoers\fR file, \fBsudo\fR may be configured
-via \s-1LAP\s0. This can be especially useful for synchronizing \fIsudoers\fR
+via \s-1LDAP\s0. This can be especially useful for synchronizing \fIsudoers\fR
in a large, distributed environment.
.PP
Using \s-1LDAP\s0 for \fIsudoers\fR has several benefits:
.IP "\fB\s-1URI\s0\fR ldap[s]://[hostname[:port]] ..." 4
.IX Item "URI ldap[s]://[hostname[:port]] ..."
Specifies a whitespace-delimited list of one or more URIs describing
-the \s-1LDAP\s0 server(s) to connect to. The \fIprotocol\fR may be either \fBldap\fR
-or \fBldaps\fR, the latter being for servers that support \s-1TLS\s0 (\s-1SSL\s0)
-encryption. If no \fIport\fR is specified, the default is port 389 for
-\&\f(CW\*(C`ldap://\*(C'\fR or port 636 for \f(CW\*(C`ldaps://\*(C'\fR. If no \fIhostname\fR is specified,
-\&\fBsudo\fR will connect to \fBlocalhost\fR. Only systems using the OpenSSL
-libraries support the mixing of \f(CW\*(C`ldap://\*(C'\fR and \f(CW\*(C`ldaps://\*(C'\fR URIs.
-The Netscape-derived libraries used on most commercial versions of
-Unix are only capable of supporting one or the other.

+\&\fBldap\fR or \fBldaps\fR, the latter being for servers that support \s-1TLS\s0
+(\s-1SSL\s0) encryption. If no \fIport\fR is specified, the default is port

+is specified, \fBsudo\fR will connect to \fBlocalhost\fR. Multiple \fB\s-1URI\s0\fR
+lines are treated identically to a \fB\s-1URI\s0\fR line containing multiple
+entries. Only systems using the OpenSSL libraries support the
+mixing of \f(CW\*(C`ldap://\*(C'\fR and \f(CW\*(C`ldaps://\*(C'\fR URIs. The Netscape-derived

.IP "\fB\s-1HOST\s0\fR name[:port] ..." 4
.IX Item "HOST name[:port] ..."
If no \fB\s-1URI\s0\fR is specified, the \fB\s-1HOST\s0\fR parameter specifies a
.IX Item "SUDOERS_BASE base"
The base \s-1DN\s0 to use when performing \fBsudo\fR \s-1LDAP\s0 queries. Typically
this is of the form \f(CW\*(C`ou=SUDOers,dc=example,dc=com\*(C'\fR for the domain

+in which case they are queried in the order specified.
.IP "\fB\s-1SUDOERS_DEBUG\s0\fR debug_level" 4
.IX Item "SUDOERS_DEBUG debug_level"
This sets the debug level for \fBsudo\fR \s-1LDAP\s0 queries. Debugging
certificated to be verified. If the server's \s-1TLS\s0 certificate cannot
be verified (usually because it is signed by an unknown certificate
authority), \fBsudo\fR will be unable to connect to it. If \fB\s-1TLS_CHECKPEER\s0\fR
-is disabled, no check is made.
+is disabled, no check is made. Note that disabling the check creates
+an opportunity for man-in-the-middle attacks since the server's
+identity will not be authenticated. If possible, the \s-1CA\s0's certificate
+should be installed locally so it can be verified.
+.IP "\fB\s-1TLS_CACERT\s0\fR file name" 4
+.IX Item "TLS_CACERT file name"
+An alias for \fB\s-1TLS_CACERTFILE\s0\fR.
.IP "\fB\s-1TLS_CACERTFILE\s0\fR file name" 4
.IX Item "TLS_CACERTFILE file name"
The path to a certificate authority bundle which contains the certificates
for all the Certificate Authorities the client knows to be valid,
e.g. \fI/etc/ssl/ca\-bundle.pem\fR.
This option is only supported by the OpenLDAP libraries.
+Netscape-derived \s-1LDAP\s0 libraries use the same certificate
+database for \s-1CA\s0 and client certificates (see \fB\s-1TLS_CERT\s0\fR).
.IP "\fB\s-1TLS_CACERTDIR\s0\fR directory" 4
.IX Item "TLS_CACERTDIR directory"
Similar to \fB\s-1TLS_CACERTFILE\s0\fR but instead of a file, it is a
