SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) NNAAMMEE sudoers.ldap - sudo LDAP configuration DDEESSCCRRIIPPTTIIOONN In addition to the standard _s_u_d_o_e_r_s file, ssuuddoo may be configured via LDAP. This can be especially useful for synchronizing _s_u_d_o_e_r_s in a large, distributed environment. Using LDAP for _s_u_d_o_e_r_s has several benefits: +o ssuuddoo no longer needs to read _s_u_d_o_e_r_s 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. +o ssuuddoo no longer exits if there is a typo in _s_u_d_o_e_r_s. It is not possible to load LDAP data into the server that does not conform to the sudoers schema, so proper syntax is guaranteed. It is still possible to have typos in a user or host name, but this will not prevent ssuuddoo from running. +o It is possible to specify per-entry options that override the global default options. _/_e_t_c_/_s_u_d_o_e_r_s only supports default options and limited options associated with user/host/commands/aliases. The syntax is complicated and can be difficult for users to understand. Placing the options directly in the entry is more natural. +o The vviissuuddoo program is no longer needed. vviissuuddoo provides locking and syntax checking of the _/_e_t_c_/_s_u_d_o_e_r_s 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. Another major difference between LDAP and file-based _s_u_d_o_e_r_s is that in LDAP, ssuuddoo-specific Aliases are not supported. For the most part, there is really no need for ssuuddoo-specific Aliases. Unix groups or user netgroups can be used in place of User_Aliases and RunasAliases. Host netgroups can be used in place of HostAliases. Since Unix groups and netgroups can also be stored in LDAP there is no real need for ssuuddoo-specific aliases. Cmnd_Aliases are not really required either since it is possible to have multiple users listed in a sudoRole. Instead of defining a Cmnd_Alias that is referenced by multiple users, one can create a sudoRole that contains the commands and assign multiple users to it. SSUUDDOOeerrss LLDDAAPP ccoonnttaaiinneerr The _s_u_d_o_e_r_s configuration is contained in the ou=SUDOers LDAP container. Sudo first looks for the cn=default entry in the SUDOers container. If found, the multi-valued sudoOption attribute is parsed in the same 1.7.4 July 12, 2010 1 SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) manner as a global Defaults line in _/_e_t_c_/_s_u_d_o_e_r_s. In the following example, the SSH_AUTH_SOCK variable will be preserved in the environment for all users. dn: cn=defaults,ou=SUDOers,dc=example,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 components: ssuuddooUUsseerr A user name, uid (prefixed with '#'), Unix group (prefixed with a '%') or user netgroup (prefixed with a '+'). ssuuddooHHoosstt A host name, IP address, IP network, or host netgroup (prefixed with a '+'). The special value ALL will match any host. ssuuddooCCoommmmaanndd A Unix command with optional command line arguments, potentially including globbing characters (aka wild cards). The special value ALL will match any command. If a command is prefixed with an exclamation point '!', the user will be prohibited from running that command. ssuuddooOOppttiioonn Identical in function to the global options described above, but specific to the sudoRole in which it resides. ssuuddooRRuunnAAssUUsseerr A user name or uid (prefixed with '#') 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. ssuuddooRRuunnAAssGGrroouupp A Unix group or gid (prefixed with '#') that commands may be run as. The special value ALL will match any group. Each component listed above should contain a single value, but there may be multiple instances of each component 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 ssuuddoo: 1.7.4 July 12, 2010 2 SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) dn: cn=%wheel,ou=SUDOers,dc=example,dc=com objectClass: top objectClass: sudoRole cn: %wheel sudoUser: %wheel sudoHost: ALL sudoCommand: ALL AAnnaattoommyy ooff LLDDAAPP ssuuddooeerrss llooookkuupp 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 checks to see if the user belongs to any of them. DDiiffffeerreenncceess bbeettwweeeenn LLDDAAPP aanndd nnoonn--LLDDAAPP ssuuddooeerrss There are 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. If there are conflicting command rules on 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 1.7.4 July 12, 2010 3 SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) sudoCommand: ALL Another difference is that negations on the Host, User or Runas are currently ignorred. For example, the following attributes do not behave the way one might expect. # does not match all but joe # rather, does not match anyone sudoUser: !joe # does not match all but joe # rather, matches everyone including Joe sudoUser: ALL sudoUser: !joe # does not match all but web01 # rather, matches all hosts including web01 sudoHost: ALL sudoHost: !web01 SSuuddooeerrss SScchheemmaa In order to use ssuuddoo's LDAP support, the ssuuddoo schema must be installed on your LDAP server. In addition, be sure to index the 'sudoUser' attribute. Three versions of the schema: one for OpenLDAP servers (_s_c_h_e_m_a_._O_p_e_n_L_D_A_P), one for Netscape-derived servers (_s_c_h_e_m_a_._i_P_l_a_n_e_t), and one for Microsoft Active Directory (_s_c_h_e_m_a_._A_c_t_i_v_e_D_i_r_e_c_t_o_r_y) may be found in the ssuuddoo distribution. The schema for ssuuddoo in OpenLDAP form is included in the EXAMPLES section. CCoonnffiigguurriinngg llddaapp..ccoonnff Sudo reads the _/_e_t_c_/_l_d_a_p_._c_o_n_f file for LDAP-specific configuration. Typically, this file is shared amongst different LDAP-aware clients. As such, most of the settings are not ssuuddoo-specific. Note that ssuuddoo parses _/_e_t_c_/_l_d_a_p_._c_o_n_f itself and may support options that differ from those described in the _l_d_a_p_._c_o_n_f(4) manual. Also note that on systems using the OpenLDAP libraries, default values specified in _/_e_t_c_/_o_p_e_n_l_d_a_p_/_l_d_a_p_._c_o_n_f or the user's _._l_d_a_p_r_c files are not used. Only those options explicitly listed in _/_e_t_c_/_l_d_a_p_._c_o_n_f that are supported by ssuuddoo are honored. Configuration options are listed below in upper case but are parsed in a case-independent manner. UURRII ldap[s]://[hostname[:port]] ... Specifies a whitespace-delimited list of one or more URIs describing the LDAP server(s) to connect to. The _p_r_o_t_o_c_o_l may be either llddaapp or llddaappss, the latter being for servers that support TLS (SSL) encryption. If no _p_o_r_t is specified, the default is port 389 for ldap:// or port 636 for ldaps://. If no _h_o_s_t_n_a_m_e is specified, 1.7.4 July 12, 2010 4 SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) ssuuddoo will connect to llooccaallhhoosstt. Multiple UURRII lines are treated identically to a UURRII line containing multiple entries. Only systems using the OpenSSL libraries support the mixing of ldap:// and ldaps:// URIs. The Netscape-derived libraries used on most commercial versions of Unix are only capable of supporting one or the other. HHOOSSTT name[:port] ... If no UURRII is specified, the HHOOSSTT parameter specifies a whitespace- delimited list of LDAP servers to connect to. Each host may include an optional _p_o_r_t separated by a colon (':'). The HHOOSSTT parameter is deprecated in favor of the UURRII specification and is included for backwards compatibility. PPOORRTT port_number If no UURRII is specified, the PPOORRTT parameter specifies the default port to connect to on the LDAP server if a HHOOSSTT parameter does not specify the port itself. If no PPOORRTT parameter is used, the default is port 389 for LDAP and port 636 for LDAP over TLS (SSL). The PPOORRTT parameter is deprecated in favor of the UURRII specification and is included for backwards compatibility. BBIINNDD__TTIIMMEELLIIMMIITT seconds The BBIINNDD__TTIIMMEELLIIMMIITT parameter specifies the amount of time, in seconds, to wait while trying to connect to an LDAP server. If multiple UURRIIs or HHOOSSTTs are specified, this is the amount of time to wait before trying the next one in the list. TTIIMMEELLIIMMIITT seconds The TTIIMMEELLIIMMIITT parameter specifies the amount of time, in seconds, to wait for a response to an LDAP query. SSUUDDOOEERRSS__BBAASSEE base The base DN to use when performing ssuuddoo LDAP queries. Typically this is of the form ou=SUDOers,dc=example,dc=com for the domain example.com. Multiple SSUUDDOOEERRSS__BBAASSEE lines may be specified, in which case they are queried in the order specified. SSUUDDOOEERRSS__DDEEBBUUGG debug_level This sets the debug level for ssuuddoo 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. BBIINNDDDDNN DN The BBIINNDDDDNN parameter specifies the identity, in the form of a Distinguished Name (DN), to use when performing LDAP operations. If not specified, LDAP operations are performed with an anonymous identity. By default, most LDAP servers will allow anonymous access. 1.7.4 July 12, 2010 5 SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) BBIINNDDPPWW secret The BBIINNDDPPWW parameter specifies the password to use when performing LDAP operations. This is typically used in conjunction with the BBIINNDDDDNN parameter. RROOOOTTBBIINNDDDDNN DN The RROOOOTTBBIINNDDDDNN parameter specifies the identity, in the form of a Distinguished Name (DN), to use when performing privileged LDAP operations, such as _s_u_d_o_e_r_s queries. The password corresponding to the identity should be stored in _/_e_t_c_/_l_d_a_p_._s_e_c_r_e_t. If not specified, the BBIINNDDDDNN identity is used (if any). LLDDAAPP__VVEERRSSIIOONN number The version of the LDAP protocol to use when connecting to the server. The default value is protocol version 3. SSSSLL on/true/yes/off/false/no If the SSSSLL parameter is set to on, true or yes, TLS (SSL) encryption is always used when communicating with the LDAP server. Typically, this involves connecting to the server on port 636 (ldaps). SSSSLL start_tls If the SSSSLL parameter is set to start_tls, the LDAP server connection is initiated normally and TLS encryption is begun before the bind credentials are sent. This has the advantage of not requiring a dedicated port for encrypted communications. This parameter is only supported by LDAP servers that honor the start_tls extension, such as the OpenLDAP server. TTLLSS__CCHHEECCKKPPEEEERR on/true/yes/off/false/no If enabled, TTLLSS__CCHHEECCKKPPEEEERR will cause the LDAP server's TLS certificated to be verified. If the server's TLS certificate cannot be verified (usually because it is signed by an unknown certificate authority), ssuuddoo will be unable to connect to it. If TTLLSS__CCHHEECCKKPPEEEERR 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 CA's certificate should be installed locally so it can be verified. TTLLSS__CCAACCEERRTT file name An alias for TTLLSS__CCAACCEERRTTFFIILLEE. TTLLSS__CCAACCEERRTTFFIILLEE 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. _/_e_t_c_/_s_s_l_/_c_a_-_b_u_n_d_l_e_._p_e_m. This option is only supported by the OpenLDAP libraries. Netscape-derived LDAP libraries use the same certificate database for CA and client certificates (see TTLLSS__CCEERRTT). TTLLSS__CCAACCEERRTTDDIIRR directory Similar to TTLLSS__CCAACCEERRTTFFIILLEE but instead of a file, it is a directory 1.7.4 July 12, 2010 6 SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) containing individual Certificate Authority certificates, e.g. _/_e_t_c_/_s_s_l_/_c_e_r_t_s. The directory specified by TTLLSS__CCAACCEERRTTDDIIRR is checked after TTLLSS__CCAACCEERRTTFFIILLEE. This option is only supported by the OpenLDAP libraries. TTLLSS__CCEERRTT file name The path to a file containing the client certificate which can be used to authenticate the client to the LDAP server. The certificate type depends on the LDAP libraries used. OpenLDAP: tls_cert /etc/ssl/client_cert.pem Netscape-derived: tls_cert /var/ldap/cert7.db When using Netscape-derived libraries, this file may also contain Certificate Authority certificates. TTLLSS__KKEEYY file name The path to a file containing the private key which matches the certificate specified by TTLLSS__CCEERRTT. The private key must not be password-protected. The key type depends on the LDAP libraries used. OpenLDAP: tls_key /etc/ssl/client_key.pem Netscape-derived: tls_key /var/ldap/key3.db TTLLSS__RRAANNDDFFIILLEE file name The TTLLSS__RRAANNDDFFIILLEE parameter specifies the path to an entropy source for systems that lack a random device. It is generally used in conjunction with _p_r_n_g_d or _e_g_d. This option is only supported by the OpenLDAP libraries. TTLLSS__CCIIPPHHEERRSS cipher list The TTLLSS__CCIIPPHHEERRSS parameter allows the administer to restrict which encryption algorithms may be used for TLS (SSL) connections. See the OpenSSL manual for a list of valid ciphers. This option is only supported by the OpenLDAP libraries. UUSSEE__SSAASSLL on/true/yes/off/false/no Enable UUSSEE__SSAASSLL for LDAP servers that support SASL authentication. SSAASSLL__AAUUTTHH__IIDD identity The SASL user name to use when connecting to the LDAP server. By default, ssuuddoo will use an anonymous connection. RROOOOTTUUSSEE__SSAASSLL on/true/yes/off/false/no Enable RROOOOTTUUSSEE__SSAASSLL to enable SASL authentication when connecting to an LDAP server from a privileged process, such as ssuuddoo. 1.7.4 July 12, 2010 7 SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) RROOOOTTSSAASSLL__AAUUTTHH__IIDD identity The SASL user name to use when RROOOOTTUUSSEE__SSAASSLL is enabled. SSAASSLL__SSEECCPPRROOPPSS none/properties SASL security properties or _n_o_n_e for no properties. See the SASL programmer's manual for details. KKRRBB55__CCCCNNAAMMEE file name The path to the Kerberos 5 credential cache to use when authenticating with the remote server. See the ldap.conf entry in the EXAMPLES section. CCoonnffiigguurriinngg nnsssswwiittcchh..ccoonnff Unless it is disabled at build time, ssuuddoo consults the Name Service Switch file, _/_e_t_c_/_n_s_s_w_i_t_c_h_._c_o_n_f, to specify the _s_u_d_o_e_r_s search order. Sudo looks for a line beginning with sudoers: and uses this to determine the search order. Note that ssuuddoo does not stop searching after the first match and later matches take precedence over earlier ones. The following sources are recognized: files read sudoers from F ldap read sudoers from LDAP In addition, the entry [NOTFOUND=return] will short-circuit the search if the user was not found in the preceding source. To consult LDAP first followed by the local sudoers file (if it exists), use: sudoers: ldap files The local _s_u_d_o_e_r_s file can be ignored completely by using: sudoers: ldap If the _/_e_t_c_/_n_s_s_w_i_t_c_h_._c_o_n_f file is not present or there is no sudoers line, the following default is assumed: sudoers: files Note that _/_e_t_c_/_n_s_s_w_i_t_c_h_._c_o_n_f is supported even when the underlying operating system does not use an nsswitch.conf file. CCoonnffiigguurriinngg nneettssvvcc..ccoonnff On AIX systems, the _/_e_t_c_/_n_e_t_s_v_c_._c_o_n_f file is consulted instead of _/_e_t_c_/_n_s_s_w_i_t_c_h_._c_o_n_f. ssuuddoo simply treats _n_e_t_s_v_c_._c_o_n_f as a variant of _n_s_s_w_i_t_c_h_._c_o_n_f; 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: 1.7.4 July 12, 2010 8 SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) sudoers = ldap, files The local _s_u_d_o_e_r_s file can be ignored completely by using: sudoers = ldap To treat LDAP as authoratative and only use the local sudoers file if the user is not present in LDAP, use: sudoers = ldap = auth, files Note that in the above example, the auth qualfier only affects user lookups; both LDAP and _s_u_d_o_e_r_s will be queried for Defaults entries. If the _/_e_t_c_/_n_e_t_s_v_c_._c_o_n_f file is not present or there is no sudoers line, the following default is assumed: sudoers = files FFIILLEESS _/_e_t_c_/_l_d_a_p_._c_o_n_f LDAP configuration file _/_e_t_c_/_n_s_s_w_i_t_c_h_._c_o_n_f determines sudoers source order _/_e_t_c_/_n_e_t_s_v_c_._c_o_n_f determines sudoers source order on AIX EEXXAAMMPPLLEESS EExxaammppllee llddaapp..ccoonnff # Either specify one or more URIs or one or more host:port pairs. # If neither is specified sudo will default to localhost, port 389. # #host ldapserver #host ldapserver1 ldapserver2:390 # # Default port if host is specified without one, defaults to 389. #port 389 # # URI will override the host and port settings. uri ldap://ldapserver #uri ldaps://secureldapserver #uri ldaps://secureldapserver ldap://ldapserver # # The amount of time, in seconds, to wait while trying to connect to # an LDAP server. bind_timelimit 30 # # The amount of time, in seconds, to wait while performing an LDAP query. timelimit 30 # # Must be set or sudo will ignore LDAP; may be specified multiple times. sudoers_base ou=SUDOers,dc=example,dc=com # # verbose sudoers matching from ldap #sudoers_debug 2 1.7.4 July 12, 2010 9 SUDOERS.LDAP(4) MAINTENANCE COMMANDS SUDOERS.LDAP(4) # # optional proxy credentials #binddn #bindpw #rootbinddn # # LDAP protocol version, defaults to 3 #ldap_version 3 # # Define if you want to use an encrypted LDAP connection. # Typically, you must also set the port to 636 (ldaps). #ssl on # # Define if you want to use port 389 and switch to # encryption before the bind credentials are sent. # Only supported by LDAP servers that support the start_tls # extension such as OpenLDAP. #ssl start_tls # # Additional TLS options follow that allow tweaking of the # SSL/TLS connection. # #tls_checkpeer yes # verify server SSL certificate #tls_checkpeer no # ignore server SSL certificate # # If you enable tls_checkpeer, specify either tls_cacertfile # or tls_cacertdir.
