sudo LDAP configuration
In addition to the standard sudoers file,
sudo may be configured via LDAP. This can be
especially useful for synchronizing sudoers in a large,
distributed environment.
Using LDAP for sudoers has several benefits:
sudo no longer needs to read
sudoers in its entirety. When LDAP is used, there are
only two or three LDAP queries per invocation. This makes it especially
fast and particularly usable in LDAP environments.visudo program is no longer needed.
visudo provides locking and syntax checking of the
/etc/sudoers file. Since LDAP updates are atomic,
locking is no longer necessary. Because syntax is checked when the data is
inserted into LDAP, there is no need for a specialized tool to check
syntax.The sudoers configuration is contained in the
‘ou=SUDOers’ LDAP container.
Sudo first looks for the
‘cn=defaults’ entry in the SUDOers
container. If found, the multi-valued sudoOption attribute
is parsed in the same manner as a global Defaults line in
/etc/sudoers. In the following example, the
SSH_AUTH_SOCK variable will be preserved in the
environment for all users.
dn: cn=defaults,ou=SUDOers,dc=my-domain,dc=com objectClass: top objectClass: sudoRole cn: defaults description: Default sudoOption's go here sudoOption: env_keep+=SSH_AUTH_SOCK
The equivalent of a sudoer in LDAP is a sudoRole. It consists of the following attributes:
#’), Unix group name or ID
(prefixed with ‘%’ or
‘%#’ respectively), user netgroup
(prefixed with ‘+’), or non-Unix
group name or ID (prefixed with ‘%:’
or ‘%:#’ respectively). User
netgroups are matched using the user and domain members only; the host
member is not used when matching. Non-Unix group support is only available
when an appropriate group_plugin is defined in the
global
defaults
sudoRole object. If a sudoUser entry
is preceded by an exclamation point,
‘!’, and the entry matches, the
sudoRole in which it resides will be ignored. Negated
sudoUser entries are only supported by version 1.9.9 or
higher.+’). The special value
ALL will match any host. Host netgroups are matched
using the host (both qualified and unqualified) and domain members only;
the user member is not used when matching. If a sudoHost
entry is preceded by an exclamation point,
‘!’, and the entry matches, the
sudoRole in which it resides will be ignored. Negated
sudoHost entries are only supported by version 1.8.18 or
higher.!’, the user will be prohibited
from running that command.
The built-in command “sudoedit” is used to
permit a user to run sudo with the
-e option (or as
sudoedit). It may take command line arguments
just as a normal command does. Unlike other commands,
“sudoedit” is a built into sudo
itself and must be specified in without a leading path.
The special value ALL will match any command.
If a command name is prefixed with a SHA-2 digest, it will
only be allowed if the digest matches. This may be useful in situations
where the user invoking sudo has write access to
the command or its parent directory. The following digest formats are
supported: sha224, sha256, sha384, and sha512. The digest name must be
followed by a colon (‘:’) and then
the actual digest, in either hex or base64 format. For example, given
the following value for sudoCommand:
sha224:0GomF8mNN3wlDt1HD9XldjJ3SNgpFdbjO1+NsQ /bin/ls
The user may only run /bin/ls if its sha224 digest matches the specified value. Command digests are only supported by version 1.8.7 or higher.
#’) that commands may be run as or
a Unix group (prefixed with a ‘%’)
or user netgroup (prefixed with a
‘+’) that contains a list of users
that commands may be run as. The special value ALL will
match any user. If a sudoRunAsUser entry is preceded by
an exclamation point, ‘!’, and the
entry matches, the sudoRole in which it resides will be
ignored. If sudoRunAsUser is specified but empty, it
will match the invoking user. If neither sudoRunAsUser
nor sudoRunAsGroup are present, the value of the
runas_default
sudoOption is used (defaults to root).
The sudoRunAsUser attribute
is only available in sudo versions 1.7.0 and
higher. Older versions of sudo use the
sudoRunAs
attribute instead. Negated sudoRunAsUser entries are
only supported by version 1.8.26 or higher.
#’) that commands may be run as.
The special value ALL will match any group. If a
sudoRunAsGroup entry is preceded by an exclamation
point, ‘!’, and the entry matches,
the sudoRole in which it resides will be ignored.
The sudoRunAsGroup attribute is only
available in sudo versions 1.7.0 and higher.
Negated sudoRunAsGroup entries are only supported by
version 1.8.26 or higher.
yyyymmddHHMMSSZ’ that can be used
to provide a start date/time for when the sudoRole will
be valid. If multiple sudoNotBefore entries are present,
the earliest is used. Timestamps must be in Coordinated Universal Time
(UTC), not the local timezone. The minute and seconds portions are
optional, but some LDAP servers require that they be present (contrary to
the RFC).
The sudoNotBefore attribute is only
available in sudo versions 1.7.5 and higher and
must be explicitly enabled via the SUDOERS_TIMED
option in /etc/sudo-ldap.conf.
yyyymmddHHMMSSZ’ that indicates an
expiration date/time, after which the sudoRole will no
longer be valid. If multiple sudoNotAfter entries are
present, the last one is used. Timestamps must be in Coordinated Universal
Time (UTC), not the local timezone. The minute and seconds portions are
optional, but some LDAP servers require that they be present (contrary to
the RFC).
The sudoNotAfter attribute is only available
in sudo versions 1.7.5 and higher and must be
explicitly enabled via the SUDOERS_TIMED option in
/etc/sudo-ldap.conf.
The sudoOrder attribute is only available in
sudo versions 1.7.5 and higher.
Each attribute listed above should contain a single value, but there may be multiple instances of each attribute type. A sudoRole must contain at least one sudoUser, sudoHost, and sudoCommand.
The following example allows users in group wheel to run any
command on any host via sudo:
dn: cn=%wheel,ou=SUDOers,dc=my-domain,dc=com objectClass: top objectClass: sudoRole cn: %wheel sudoUser: %wheel sudoHost: ALL sudoCommand: ALL
When looking up a sudoer using LDAP there are only two or three LDAP queries per invocation. The first query is to parse the global options. The second is to match against the user's name and the groups that the user belongs to. (The special ALL tag is matched in this query too.) If no match is returned for the user's name and groups, a third query returns all entries containing user netgroups and other non-Unix groups and checks to see if the user belongs to any of them.
If timed entries are enabled with the SUDOERS_TIMED configuration directive, the LDAP queries include a sub-filter that limits retrieval to entries that satisfy the time constraints, if any.
If the NETGROUP_BASE configuration directive is
present (see Configuring
ldap.conf below), queries are performed to determine the list of
netgroups the user belongs to before the sudoers query. This makes it
possible to include netgroups in the sudoers query string in the same manner
as Unix groups. The third query mentioned above is not performed unless a
group provider plugin is also configured. The actual LDAP queries performed
by sudo are as follows:
For sites with a large number of netgroups, using
NETGROUP_BASE can significantly speed up
sudo's execution time.
One of the major differences between LDAP and file-based
sudoers is that in LDAP,
sudo-specific Aliases are not supported.
For the most part, there is little need for
sudo-specific Aliases. Unix groups, non-Unix groups
(via the group_plugin), or user netgroups can be used in
place of User_Aliases and Runas_Aliases. Host netgroups can be used in place
of Host_Aliases. Since groups and netgroups can also be stored in LDAP there
is no real need for sudo-specific aliases.
There are also some subtle differences in the way sudoers is handled once in LDAP. Probably the biggest is that according to the RFC, LDAP ordering is arbitrary and you cannot expect that Attributes and Entries are returned in any specific order.
The order in which different entries are applied can be controlled using the sudoOrder attribute, but there is no way to guarantee the order of attributes within a specific entry. If there are conflicting command rules in an entry, the negative takes precedence. This is called paranoid behavior (not necessarily the most specific match).
Here is an example:
# /etc/sudoers: # Allow all commands except shell johnny ALL=(root) ALL,!/bin/sh # Always allows all commands because ALL is matched last puddles ALL=(root) !/bin/sh,ALL # LDAP equivalent of johnny # Allows all commands except shell dn: cn=role1,ou=Sudoers,dc=my-domain,dc=com objectClass: sudoRole objectClass: top cn: role1 sudoUser: johnny sudoHost: ALL sudoCommand: ALL sudoCommand: !/bin/sh # LDAP equivalent of puddles # Notice that even though ALL comes last, it still behaves like # role1 since the LDAP code assumes the more paranoid configuration dn: cn=role2,ou=Sudoers,dc=my-domain,dc=com objectClass: sudoRole objectClass: top cn: role2 sudoUser: puddles sudoHost: ALL sudoCommand: !/bin/sh sudoCommand: ALL
The cvtsudoers(1) utility can be used to convert between file-based and LDAP sudoers. However, there are features in the file-based sudoers that have no equivalent in LDAP-based sudoers (and vice versa). These cannot be converted automatically.
For example, a Cmnd_Alias in a sudoers file may be converted to a sudoRole that contains multiple commands. Multiple users and/or groups may be assigned to the sudoRole.
Also, host, user, runas, and command-based Defaults entries are not supported. However, a sudoRole may contain one or more sudoOption attributes which can often serve the same purpose.
Consider the following sudoers lines:
Cmnd_Alias PAGERS = /usr/bin/more, /usr/bin/pg, /usr/bin/less Defaults!PAGERS noexec alice, bob ALL = ALL
In this example, alice and bob are allowed to run all commands, but the commands listed in PAGERS will have the noexec flag set, preventing shell escapes.
When converting this to LDAP, two sudoRole objects can be used:
dn: cn=PAGERS,ou=SUDOers,dc=my-domain,dc=com objectClass: top objectClass: sudoRole cn: PAGERS sudoUser: alice sudoUser: bob sudoHost: ALL sudoCommand: /usr/bin/more sudoCommand: /usr/bin/pg sudoCommand: /usr/bin/less sudoOption: noexec sudoOrder: 900 dn: cn=ADMINS,ou=SUDOers,dc=my-domain,dc=com objectClass: top objectClass: sudoRole cn: ADMINS sudoUser: alice sudoUser: bob sudoHost: ALL sudoCommand: ALL sudoOrder: 100
In the LDAP version, the sudoOrder attribute is used to guarantee that the PAGERS sudoRole with noexec has precedence. Unlike the sudoers version, the LDAP version requires that all users for whom the restriction should apply be assigned to the PAGERS sudoRole. Using a Unix group or netgroup in PAGERS rather than listing each user would make this easier to maintain.
Per-user Defaults entries can be emulated by using one or more sudoOption attributes in a sudoRole. Consider the following sudoers lines:
User_Alias ADMINS = john, sally Defaults:ADMINS !authenticate ADMINS ALL = (ALL:ALL) ALL
In this example, john and sally are allowed to run any command as any user or group.
When converting this to LDAP, we can use a Unix group instead of the User_Alias.
dn: cn=admins,ou=SUDOers,dc=my-domain,dc=com objectClass: top objectClass: sudoRole cn: admins sudoUser: %admin sudoHost: ALL sudoRunAsUser: ALL sudoRunAsGroup: ALL sudoCommand: ALL sudoOption: !authenticate
This assumes that users john and sally are members of the “admins” Unix group.
In order to use sudo's LDAP support, the
sudo schema must be installed on your LDAP server.
In addition, be sure to index the sudoUser attribute.
The sudo distribution includes versions of
the sudoers schema for multiple LDAP servers:
The schema in OpenLDAP format is also included in the EXAMPLES section.
Sudo reads the /etc/sudo-ldap.conf file
for LDAP-specific configuration. Typically, this file is shared between
different LDAP-aware clients. As such, most of the settings are not
sudo-specific. The
/etc/sudo-ldap.conf file is parsed by
sudo itself and may support options that differ from
those described in the system's ldap.conf(5) manual. The
path to ldap.conf may be overridden via the
ldap_conf
plugin argument in sudo.conf(5).
On systems using the OpenLDAP libraries, default values specified in /etc/openldap/ldap.conf or the user's .ldaprc files are not used.
sudo supports a variety of LDAP library
implementations, including OpenLDAP, Netscape-derived (also used by Solaris
and HP-UX), and IBM LDAP (aka Tivoli). Some options are specific to certain
LDAP implementations or have implementation-specific behavior. These
differences are noted below where applicable.
Only those options explicitly listed in
/etc/sudo-ldap.conf as being supported by
sudo are honored. Configuration options are listed
below in upper case but are parsed in a case-independent manner.
Lines beginning with a pound sign
(‘#’) are ignored. Leading white space
is removed from the beginning of lines.
BINDPW base64:dGVzdA==
If a plaintext password is used, it should be a simple string
without quotes. Plain text passwords may not include the comment
character (‘#’) and the escaping
of special characters with a backslash
(‘\’) is not supported.
:’). The HOST
parameter is deprecated in favor of the URI
specification and is included for backward compatibility only.This option is only relevant when using SASL authentication (see below).
ou=netgroup,dc=my-domain,dc=com’
for the domain my-domain.com. Multiple NETGROUP_BASE
lines may be specified, in which case they are queried in the order
specified.
This option can be used to query a user's netgroups
directly via LDAP which is usually faster than fetching every
sudoRole object containing a
sudoUser that begins with a
‘+’ prefix. The NIS schema used by
some LDAP servers need a modification to support querying the
nisNetgroup object by its
nisNetgroupTriple member. OpenLDAP's
slapd requires
the following change to the nisNetgroupTriple
attribute:
attributetype ( 1.3.6.1.1.1.1.14 NAME 'nisNetgroupTriple' DESC 'Netgroup triple' EQUALITY caseIgnoreIA5Match SUBSTR caseIgnoreIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 )
attribute=value’ or
‘(&(attribute=value)(attribute2=value2))’.
The default search filter is:
‘objectClass=nisNetgroup’. If
ldap_filter is omitted, no search filter will be
used.
This option is only used when querying netgroups directly via LDAP.
sudo.sudo will use an anonymous connection.
This option is only relevant when using SASL authentication.
sudo will use
GSSAPI authentication.This option is only relevant when using SASL authentication.
sudo LDAP
queries. Typically this is of the form
‘ou=SUDOers,dc=my-domain,dc=com’ for
the domain my-domain.com. Multiple SUDOERS_BASE lines
may be specified, in which case they are queried in the order
specified.sudo LDAP queries.
Debugging information is printed to the standard error. A value of 1
results in a moderate amount of debugging information. A value of 2 shows
the results of the matches themselves. This parameter should not be set in
a production environment as the extra information is likely to confuse
users.
The SUDOERS_DEBUG parameter is
deprecated and will be removed in a future release. The same information
is now logged via the sudo debugging framework
using the “ldap” subsystem at priorities
diag and
info
for
debug_level
values 1 and 2 respectively. See the sudo.conf(5)
manual for details on how to configure sudo
debugging.
sudo LDAP query. Typically, this is
of the form ‘attribute=value’ or
‘(&(attribute=value)(attribute2=value2))’.
The default search filter is:
‘objectClass=sudoRole’. If
ldap_filter is omitted, no search filter will be
used.This option is only supported by the OpenLDAP libraries. Netscape-derived LDAP libraries use the same certificate database for CA and client certificates (see TLS_CERT).
This option is only supported by the OpenLDAP libraries.
tls_cert
/etc/ssl/client_cert.pem’tls_cert
/var/ldap/cert7.db’When using Netscape-derived libraries, this file may also contain Certificate Authority certificates.
sudo will be unable to connect to it.
If TLS_CHECKPEER is disabled, no check is made.
Disabling this check creates an opportunity for man-in-the-middle attacks
since the server's identity will not be authenticated. If possible, the
CA's certificate should be installed locally so it can be verified.
This option is not supported by the IBM LDAP libraries.
tls_key
/etc/ssl/client_key.pem’tls_key /var/ldap/key3.db’tls_key
/usr/ldap/ldapkey.kdb’When using IBM LDAP libraries, this file may also contain Certificate Authority and client certificates and may be encrypted.
This option is not supported by Netscape-derived libraries.
TLS_KEYPW base64:dGVzdA==
If a plaintext password is used, it should be a simple string
without quotes. Plain text passwords may not include the comment
character (‘#’) and the escaping
of special characters with a backslash
(‘\’) is not supported. If this
option is used, /etc/sudo-ldap.conf must not be
world-readable to avoid exposing the password. Alternately, a
stash file can be used to store the password in
encrypted form (see below).
If no TLS_KEYPW is
specified, a stash file will be used if it exists. The
stash file must have the same path as the file
specified by TLS_KEY, but use a
‘.sth’ file extension instead of
‘.kdb’, for example
‘ldapkey.sth’. The default
‘ldapkey.kdb’ that ships with the
IBM Tivoli Directory Server is encrypted with the password
‘ssl_password’. The
gsk8capicmd
utility can be used to manage the key database and create a
stash file.
This option is only supported by the IBM LDAP libraries.
sudo will be unable to
connect to it. The following level values are
supported:
This option is only supported by the OpenLDAP libraries. Other LDAP libraries only support the TLS_CHECKPEER parameter.
This option is only supported by the OpenLDAP libraries.
ldap://’ or port 636 for
‘ldaps://’. If no
hostname
is specified, sudo will connect to
localhost.
Multiple URI lines are treated identically to a
URI line containing multiple entries. Only systems using
the OpenSSL libraries support the mixing of
‘ldap://’ and
‘ldaps://’ URIs. Both the
Netscape-derived and IBM LDAP libraries used on most commercial versions
of Unix are only capable of supporting one or the other.See the ldap.conf entry in the EXAMPLES section.
Unless it is disabled at build time, sudo
consults the Name Service Switch file,
/etc/nsswitch.conf, to specify the
sudoers search order. Sudo looks for a line beginning with
sudoers: and uses this to determine the search order. By
default, sudo does not stop searching after the
first match and later matches take precedence over earlier ones (unless
‘[SUCCESS=return]’ is used, see
below). The following sources are recognized:
In addition, a subset of
nsswitch.conf-style action statements is supported,
specifically ‘[SUCCESS=return]’ and
‘[NOTFOUND=return]’. These will
unconditionally terminate the search if the user was either found
‘[SUCCESS=return]’ or not found
‘[NOTFOUND=return]’ in the immediately
preceding source. Other action statements tokens are not supported, nor is
test negation with ‘!’.
To consult LDAP first followed by the local sudoers file (if it exists), use:
sudoers: ldap files
To consult LDAP only when no match is found in the local sudoers file (if it exists), use:
sudoers: files [SUCCESS=return] ldap
The local sudoers file can be ignored completely by using:
sudoers: ldap
If the /etc/nsswitch.conf file is not present or there is no sudoers line, the following default is assumed:
sudoers: files
The /etc/nsswitch.conf file is supported even when the underlying operating system does not support it, except on AIX (see below).
On AIX systems, the /etc/netsvc.conf file
is consulted instead of /etc/nsswitch.conf.
sudo simply treats
netsvc.conf as a variant of
nsswitch.conf; information in the previous section
unrelated to the file format itself still applies.
To consult LDAP first followed by the local sudoers file (if it exists), use:
sudoers = ldap, files
The local sudoers file can be ignored completely by using:
sudoers = ldap
To treat LDAP as authoritative and only use the local sudoers file if the user is not present in LDAP, use:
sudoers = ldap = auth, files
In the above example, the auth qualifier only affects user lookups; both LDAP and sudoers will be queried for Defaults entries.
If the /etc/netsvc.conf file is not present or there is no sudoers line, the following default is assumed:
sudoers = files
On systems with the
System
Security Services Daemon (SSSD) and where
sudo has been built with SSSD support, it is
possible to use SSSD to cache LDAP sudoers rules. To use
SSSD as the sudoers source, you should use
sss instead
of ldap for the sudoers entry in
/etc/nsswitch.conf. The
/etc/sudo-ldap.conf file is not used by the SSSD
sudo back end. See sssd-sudo(5)
for more information on configuring sudo to work
with SSSD.
