DESCRIPTION
The ldapsearch utility opens a connection to an LDAP server, binds, and
performs a search using the filter filter.
If ldapsearch finds one or more entries, the attributes specified by
attrs are retrieved and the entries and values are printed to standard
output. If no attrs are listed, all attributes are returned.
Output Format
If one or more entries are found, each entry is written to standard
output in the form:
dn: Distinguished Name (DN)
attributename: value
attributename: value
attributename: value
...
Multiple entries are separated with a single blank line. If the -F
option is used to specify a different separator character, this charac‐
ter is used instead of the : character. If the -t option is used, the
name of a temporary file is returned in place of the actual value. If
the -A option is given, only the "attributename" is returned and not
the attribute value.
OPTIONS
The following options are supported:
-A
Retrieve attributes only (no values). This is useful when you just
want to see whether an attribute is present in an entry and are not
interested in the specific value.
-a deref
Specify how aliases dereferencing is done. The possible values for
deref are never, always, search, or find to specify respectively
that aliases are never dereferenced, always dereferenced, derefer‐
enced when searching, or dereferenced only when finding the base
object for the search. The default is to never dereference aliases.
-B
Display non-ASCII values and use the old non-LDIF format. This
option disables the default -L option.
-b searchbase
Use searchbase as the starting point for the search instead of the
default.
-C pattern
Persistent search. Perform a search that keeps the connection open
and displays results whenever entries matching the scope and filter
of the search are added, modified, or removed. With this option,
the ldapsearch tool runs indefinitely; you must type Control-c to
stop it. The pattern has the following format:
ps:changeType[:changesOnly[:entryChangeControls]]
-c authzid
Specifies the getEffectiveRights control authzid. For example:
dn:uid=bjensen,dc=example,dc=com
-D bindDN
Use the distinguished name bindDN to bind to the directory.
-d debuglevel
Set the LDAP debugging level. Useful levels of debugging for
ldapsearch are:
1 Trace
2 Packets
4 Arguments
32 Filters
128 Access control
To request more than one category of debugging information, add the
masks. For example, to request trace and filter information, spec‐
ify a debuglevel of 33.
-E
Ask server to expose (report) bind identity by means of authentica‐
tion response control.
-e
Minimize base-64 encoding of values.
-F sep
Use sep as the field separator between attribute names and values.
If this option has been specified, the -L option is ignored.
-f file
Read a series of lines from file, performing one LDAP search for
each line. In this case, the filter given on the command line is
treated as a pattern where the first occurrence of %s is replaced
with a line from file. If file is a single - character, then the
lines are read from standard input.
-G pattern
Virtual list view. Retrieve only a portion of all results, as
determined by the index or value of the search target and the num‐
ber of entries to be returned before and after the target. This
option always requires the -S and -x options to specify the sorting
order on the server.
-?
Display the usage help text that briefly describes all options.
-H
Display the usage help text that briefly describes all options.
-h ldaphost
Specify an alternate host on which the secure LDAP server is run‐
ning.
-i locale
Specify the character set to use for command-line input. The
default is the character set specified in the LANG environment
variable. You might want to use this option to perform the conver‐
sion from the specified character set to UTF8, thus overriding the
LANG setting. Using this argument, you can input the bind DN, base
DN, and the search filter pattern in the specified character set.
The ldapsearch tool converts the input from these arguments before
it processes the search request. For example, -i no indicates that
the bind DN, base DN, and search filter are provided in Norwegian.
This argument only affects the command-line input. If you specify a
file containing a search filter (with the -f option), ldapsearch
does not convert the data in the file.
-j filename
Specify a file containing the password for the bind DN or the pass‐
word for the SSL client's key database. To protect the password,
use this option in scripts and place the password in a secure file.
This option is mutually exclusive of the -w and -W options.
-J [:criticality[:value|::b64value|b64value|:fileurl]]
Criticality is a boolean value (default is false).
-k path
Specify the path to a directory containing conversion routines.
These routines are used if you want to specify a locale that is not
supported by default by your directory server. This is for NLS sup‐
port.
-L
Display search results in LDIF format. This option also turns on
the -B option. This behavior is the default.
-l timelimit
Wait at most timelimit seconds for a search to complete.
-M
Manage smart referrals. When they are the target of the operation,
search the entry containing the referral instead of the entry
obtained by following the referral.
-N certificate
Specify the certificate name to use for certificate-based client
authentication. For example: -N "Directory-Cert".
-n
Show what would be done, but do not actually perform the search.
Useful in conjunction with -v and -d for debugging.
-O hopLimit
Specify the maximum number of referral hops to follow while finding
an entry to modify. By default, there is no limit.
-o attributename=value
For SASL mechanisms and other options such as security properties,
mode of operation, authorization ID, authentication ID, and so
forth.
The different attribute names and their values are as follows:
secProp="number"
For defining SASL security properties.
realm="value"
Specifies SASL realm (default is realm=none).
authzid="value"
Specify the authorization ID name for SASL bind.
authid="value"
Specify the authentication ID for SASL bind.
mech="value"
Specifies the various SASL mechanisms.
-P path
Specify the path and filename of the client's certificate database.
For example:
-P /home/uid/.netscape/cert7.db
When using the command on the same host as the directory server,
you can use the server's own certificate database. For example:
-P installDir/lapd-serverID/alias/cert7.db
Use the -P option alone to specify server authentication only.
-p ldapport
Specify an alternate TCP port where the secure LAPD server is lis‐
tening.
-R
Do not automatically follow referrals returned while searching.
-r
Display the output of the ldapsearch command in the old format.
-S [-]attribute
Specify an attribute for sorting the entries returned by the
search. The sort criteria is alphabetical on the attribute's value
or reverse alphabetical with the form -attribute. You can give mul‐
tiple -S options to refine the sorting, For example:
-S sn -S givenname
By default, the entries are not sorted. Use the -x option to per‐
form server-side sorting.
-s scope
Specify the scope of the search. The possible values of scope are
base, one, or sub to specify respectively a base object, one-level,
or subtree search. The default is sub.
-T
Format the output of search results so that no line breaks are used
within individual attribute values.
-t
Write retrieved values to a set of temporary files. This is useful
for dealing with non-ASCII values such as jpegPhoto or audio.
-U
URL format (valid only with the -t option). When using temporary
file output, the standard output of the tool includes the URL of
the file instead of the attributes value. For example:
jpegPhoto:< file:/tmp/ldapsearch-jpegPhoto-YzaOMh
-u
Include the user-friendly form of the Distinguished Name (DN) in
the output.
-V version
Specify the LDAP protocol version number to be used for the delete
operation, either 2 or 3. LDAP v3 is the default. Specify LDAP v2
when connecting to servers that do not support v3.
-v
Run in verbose mode, with diagnostics written to standard output.
-W password
Specify the password for the client's key database given in the -P
option. This option is required for certificate-based client
authentication. Specifying password on the command line has secu‐
rity issues because the password can be seen by others on the sys‐
tem by means of the ps command. Use the -j instead to specify the
password from the file. This option is mutually exclusive of -j.
-w passwd
Use passwd as the password for authentication to the directory.
When you use -w passwd to specify the password to be used for
authentication, the password is visible to other users of the sys‐
tem by means of the ps command, in script files or in shell his‐
tory. If you use the ldapsearch command without this option, the
command prompts for the password and read it from standard in. When
used without the -w option, the password is not visible to other
users.
-x
Use with the -S option to specify that search results be sorted on
the server rather than by the ldapsearch command running on the
client. This is useful if you want to sort according to a matching
rule, as with an international search. It is usually faster to sort
on the server, if that is supported, rather than on the client.
-Y proxyDN
Specify the proxy DN (proxied authorization id) to use for the mod‐
ify operation, usually in double quotes (" ") for the shell.
-Z
Specify that SSL be used to provide certificate-based client
authentication. This option requires the -N and SSL password and
any other of the SSL options needed to identify the certificate and
the key database.
-z sizelimit
Retrieve at most sizelimit entries for a search to complete.
EXAMPLES
Example 1: Performing a Subtree Search
The following command performs a subtree search (using the default
search base) for entries with a commonName of "mark smith". The common‐
Name and telephoneNumber values is retrieved and printed to standard
output. Use the -r option to display this output in the old format.
example% ldapsearch "cn=mark smith" cn telephoneNumber
The output looks something like this:
dn: Mark D Smith, ou=Sales, ou=Atlanta, ou=People, o=XYZ, c=US
cn: Mark Smith
cn: Mark David Smith
cn: Mark D Smith 1
cn: Mark D Smith
telephoneNumber: +1 123 456-7890
dn: Mark C Smith, ou=Distribution, ou=Atlanta, ou=People, o=XYZ, c=US
cn: Mark Smith
cn: Mark C Smith 1
cn: Mark C Smith
telephoneNumber: +1 123 456-9999
Example 2: Performing a Subtree Search Using the Default Search Base
The following command performs a subtree search using the -r option to
display in old style format with a default search base for entries with
user id of mcs. The user-friendly form of the entry's DN is output
after the line that contains the DN itself, and the jpegPhoto and audio
values are retrieved and written to temporary files.
ldapsearch-r -u -t "uid=mcs" -r jpegPhoto audio
The output might look like this if one entry with one value for each of
the requested attributes is found:
cn=Mark C Smith, ou=Distribution, ou=Atlanta, ou=People, o=XYZ, c=US
Mark C Smith, Distribution, Atlanta, People, XYZ, US
audio=/tmp/ldapsearch-audio-a19924
jpegPhoto=/tmp/ldapsearch-jpegPhoto-a19924
Example 3: Performing a One-Level Search
The following command performs a one-level search at the c=US level for
all organizations whose organizationName begins with XY.
example% ldapsearch-s one -b "c=US" "o=XY*" o description
The organizationName and description attribute values are retrieved and
printed to standard output, resulting in output similar to this:
dn: o=XYZ c=US
o: XYZ
description: XYZ Corporation
dn: o="XY Trading Company", c=US
o: XY Trading Company
description: Import and export specialists
dn: o=XYInternational, c=US
o: XYInternational
o: XYI
o: XY International
Example 4: Performing a Subtree Search on an IPv6 Server
The following command performs a subtree search using the default
search base for entries with a user id of mcs on an IPv6 (that is, -h)
server:
example% ldapsearch-u -h '['fec0::111:a00:20ff:fea3:edcf']' \
-t "uid=mcs" jpegPhoto audio
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred. A diagnostic message is written to
standard error.
