B.3 LDAP Tools


OpenLDAP's set
of LDAP client tools can be used to communicate with any LDAPv3
server (see Table B-6).




































































































Table B-6. Command-line options common to ldapsearch, ldapcompare, ldapadd, ldapdelete, ldapmodify, and ldapmodrdn

Option


Description


-d integer


Specifies what debugging information to log. See the
loglevel slapd.conf parameter
for a listing of log levels.


-D binddn


Specifies the DN to use for binding to the LDAP server.


-e [!]ctrl[=ctrlparam]


Defines an LDAP control to be used on the current operation. See also
the -M option for the manageDSAit control.


-f filename


Specifies the file containing the LDIF entries to be used in the
operations.


-H URI


Defines the LDAP URI to be used in the connection request.


-I


Enables the SASL "interactive"
mode. By default, the client prompts for information only when
necessary.


-k


Enables Kerberos 4 authentication.


-K


Enables only the first step of the Kerberos 4 bind for authentication.


-M-MM


Enable the Manager DSA IT control. This option is necessary when
modifying an entry that is a referral or an alias.
-MM requires that the Manager DSA IT control be
supported by the server.


-n


Does not perform the search; just displays what would be done.


-O security_properties


Defines the SASL security properties for authentication. See previous
information on the sasl-secprops parameter in
slapd.conf.


-P [2|3]


Defines which protocol version to use in the connection (Version 2 or
3). The default is LDAP v3.


-Q


Suppresses SASL-related messages such as how the authentication
mechanism is used, username, and realm.


-R sasl_realm


Defines the realm to be used by the SASL authentication mechanism.


-U username


Defines the username to be used by the SASL authentication mechanism.


-v


Enables verbose mode.


-w password


Specifies the password to be used for authentication.


-W


Instructs the client to prompt for the password.


-x


Enables simple authentication. The default is to use SASL
authentication.


-X id


Defines the SASL authorization identity. The identity has the form
dn:dn
oru:user. The default
is to use the same authorization identity that the user
authenticated.


-y passwdfile


Instructs the ldap tool to read the password for
a simple bind from the given filename.


-Y sasl_mechanism


Tells the client which SASL mechanism should be used. The bind
request will fail if the server does not support the chosen
mechanism.


-Z-ZZ


Issue a StartTLS request. Use of -ZZ makes the
support of this request mandatory for a successful connection.


B.3.1 ldapadd(1), ldapmodify(1)


These
tools send updates to directory servers (see Table B-7).




















Table B-7. ldapadd/ldapmodify options

Option


Description


-a


Adds entries. This option is the default for
ldapadd.


-r


Replaces (or modifies) entries and values. This is the default for
ldapmodify.


-F


Forces all change records to be used from the input.


B.3.2 ldapcompare(1)


This tool
asks a directory server to compare two values:

ldapcompare [options] DN <attr:value|attr::b64value>.

There are no additional command-line flags for this tool.


B.3.3 ldapdelete(1)


This tool
deletes entries from an LDAP directory (see Table B-8).












Table B-8. ldapdelete [option] DN

Option


Description


-r


Deletes the subtree whose root is designated by DN. The delete is not
performed atomically.


B.3.4 ldapmodrdn(1)


This tool
changes the RDN of an entry in an LDAP directory (see Table B-9).




















Table B-9. ldapmodrdn [options] [dn rdn]

Option


Description


-c


Instructs ldapmodrdn to continue if errors
occur. By default, it terminates if there is an error.


-r


Removes the old RDN value. The default behavior is to add another
value of the RDN and leave the old value intact. The default behavior
makes it easier to modify a directory without leaving orphaned
entries.


-s new_superior_node


Defines the new superior, or parent, entry under which the renamed
entry should be located.


B.3.5 ldappasswd(1)


This tool
changes the password stored in a directory entry (see Table B-10).
























Table B-10. ldappasswd [options] [user]

Option


Description


-a secret


The old password value


-A


Prompt for the old password


-s new_secret


The new password value


-S


Prompt for the new password


B.3.6 ldapsearch(1)


This tool
issues LDAP search queries to directory servers (see Table B-11).
























































Table B-11. ldapsearch [options] [filter [attributes...]]

Option


Description


-a [never|always|search|find]


Specifies how to handle aliases when they are located during a
search. Possible values include never (default),
always, search, or
find.


-A


For any entries found, returns the attribute names, but not their
values.


-b basedn


Defines the base DN for the directory search.


-F prefix


Defines the URL prefix for filenames. The default is to use the value
stored in $LDAP_FILE_URI_PREFIX.


-l limit


Defines a time limit (in seconds) for the server in the search.


-L-LL-LLL


Print the resulting output in LDIF v1 format.
-LL causes the result to be printed in LDIF
format without comments. -LLL prints the
resulting output in LDIF format without comments and without version
information.


-s [sub|base|one]


Defines the scope of the search to be base,
one, or sub (the default).


-S attribute


Causes the ldapsearch client to sort the results
by the value of attribute.


-t-tt


Write binary values to files in a temporary directory defined by the
-T option. -tt specifies
that all values should be written to files in a temporary directory
defined by the -T option.


-T directory


Defines the directory used to store the resulting output files. The
default is the directory specified by
$LDAP_TMPDIR.
