DESCRIPTION
ldapsearch is a shell-accessible interface to the
ldap_search(3) library call.
ldapsearch opens a connection to an LDAP server, binds, and
performs a search using specified parameters. The filter
should conform to the string representation for search
filters as defined in RFC 2254. If not provided, the
default filter, (objectClass=*), is used.
If ldapsearch finds one or more entries, attrs are returned.
If * is listed, all user attributes are returned. If + is
listed, all operational attributes are returned. If no
attrs are listed, all user attributes are returned. If only
1.1 is listed, no attributes will be returned.
OPTIONS
-n Show what would be done, but don't actually perform the
search. Useful for debugging in conjunction with -v.
-u Include the User Friendly Name form of the Dis-
tinguished Name (DN) in the output.
-v Run in verbose mode, with many diagnostics written to
standard output.
-k Use Kerberos IV authentication instead of simple
authentication. It is assumed that you already have a
valid ticket granting ticket. ldapsearch must be com-
piled with Kerberos support for this option to have any
effect.
-K Same as -k, but only does step 1 of the Kerberos IV
bind. This is useful when connecting to a slapd and
there is no x500dsa.hostname principal registered with
your Kerberos Domain Controller(s).
-t Write retrieved values to a set of temporary files.
This is useful for dealing with non-ASCII values such
as jpegPhoto or audio.

-A Retrieve attributes only (no values). This is useful
when you just want to see if an attribute is present in
an entry and are not interested in the specific values.
-L Search results are display in LDAP Data Interchange
Format detailed in ldif(5). A single -L restricts the
output to LDIFv1. A second -L disables comments. A
third -L disables printing of the LDIF version. The
default is to use an extended version of LDIF.
-M[M]
Enable manage DSA IT control. -MM makes control criti-
cal.
-S attribute
Sort the entries returned based on attribute. The
default is not to sort entries returned. If attribute
is a zero-length string (""), the entries are sorted by
the components of their Distingished Name. See
ldap_sort(3) for more details. Note that ldapsearch
normally prints out entries as it receives them. The
use of the -S option defeats this behavior, causing all
entries to be retrieved, then sorted, then printed.
-d debuglevel
Set the LDAP debugging level to debuglevel. ldapsearch
must be compiled with LDAP_DEBUG defined for this
option to have any effect.
-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.
-x Use simple authentication instead of SASL.
-D binddn
Use the Distinguished Name binddn to bind to the LDAP
directory.
-W Prompt for simple authentication. This is used instead
of specifying the password on the command line.
-w passwd
Use passwd as the password for simple authentication.
-y passwdfile
Use complete contents of passwdfile as the password for
simple authentication.

LDAPSEARCH(1) USER COMMANDS LDAPSEARCH(1)
-H ldapuri
Specify URI(s) referring to the ldap server(s).
-h ldaphost
Specify an alternate host on which the ldap server is
running. Deprecated in favor of -H.
-p ldapport
Specify an alternate TCP port where the ldap server is
listening. Deprecated in favor of -H.
-b searchbase
Use searchbase as the starting point for the search
instead of the default.
-s base|one|sub
Specify the scope of the search to be one of base, one,
or sub to specify a base object, one-level, or subtree
search. The default is sub.
-a never|always|search|find
Specify how aliases dereferencing is done. Should be
one of never, always, search, or find to specify that
aliases are never dereferenced, always dereferenced,
dereferenced when searching, or dereferenced only when
locating the base object for the search. The default
is to never dereference aliases.
-P 2|3
Specify the LDAP protocol version to use.
-l timelimit
wait at most timelimit seconds for a search to com-
plete. A timelimit of 0 (zero) removes the ldap.conf
limit. A server may impose a maximal timelimit which
only the root user may override.
-z sizelimit
retrieve at most sizelimit entries for a search. A
sizelimit of 0 (zero) removes the ldap.conf limit. A
server may impose a maximal sizelimit which only the
root user may override.
-O security-properties
Specify SASL security properties.
-I Enable SASL Interactive mode. Always prompt. Default
is to prompt only as needed.
-Q Enable SASL Quiet mode. Never prompt.
-U authcid
OpenLDAP LDVERSION Last change: RELEASEDATE 3
LDAPSEARCH(1) USER COMMANDS LDAPSEARCH(1)
Specify the authentication ID for SASL bind. The form
of the ID depends on the actual SASL mechanism used.
-R realm
Specify the realm of authentication ID for SASL bind.
The form of the realm depends on the actual SASL
mechanism used.
-X authzid
Specify the requested authorization ID for SASL bind.
authzid must be one of the following formats:
dn:<distinguished name> or u:<username>
-Y mech
Specify the SASL mechanism to be used for authentica-
tion. If it's not specified, the program will choose
the best mechanism the server knows.
-Z[Z]
Issue StartTLS (Transport Layer Security) extended
operation. If you use -ZZ, the command will require the
operation to be successful.
OUTPUT FORMAT
If one or more entries are found, each entry is written to
standard output in LDAP Data Interchange Format or ldif(5):
version: 1
# bjensen, example, net
dn: uid=bjensen,dc=example,dc=net
objectClass: person
objectClass: dcObject
uid: bjensen
cn: Barbara Jensen
sn: Jensen
...
If the -t option is used, the URI of a temporary file is
used in place of the actual value. If the -A option is
given, only the "attributename" part is written.
EXAMPLE
The following command:
ldapsearch -LLL "(sn=smith)" cn sn telephoneNumber
will perform a subtree search (using the default search base
defined in ldap.conf(5)) for entries with a surname (sn) of
smith. The common name (cn), surname (sn) and
telephoneNumber values will be retrieved and printed to
standard output. The output might look something like this
OpenLDAP LDVERSION Last change: RELEASEDATE 4
LDAPSEARCH(1) USER COMMANDS LDAPSEARCH(1)
if two entries are found:
dn: uid=jts,dc=example,dc=com
cn: John Smith
cn: John T. Smith
sn: Smith
sn;lang-en: Smith
sn;lang-de: Schmidt
telephoneNumber: 1 555 123-4567
dn: uid=sss,dc=example,dc=com
cn: Steve Smith
cn: Steve S. Smith
sn: Smith
sn;lang-en: Smith
sn;lang-de: Schmidt
telephoneNumber: 1 555 765-4321
The command:
ldapsearch -LLL -u -t "(uid=xyz)" jpegPhoto audio
will perform a subtree search using the default search base
for entries with user id of "xyz". The user friendly form
of the entry's DN will be output after the line that con-
tains the DN itself, and the jpegPhoto and audio values will
be retrieved and written to temporary files. The output
might look like this if one entry with one value for each of
the requested attributes is found:
dn: uid=xyz,dc=example,dc=com
ufn: xyz, example, com
audio:< file:///tmp/ldapsearch-audio-a19924
jpegPhoto:< file:///tmp/ldapsearch-jpegPhoto-a19924
This command:
ldapsearch -LLL -s one -b "c=US" "(o=University*)" o description
will perform a one-level search at the c=US level for all
entries whose organization name (o) begins begins with
University. The organization name and description attribute
values will be retrieved and printed to standard output,
resulting in output similar to this:
dn: o=University of Alaska Fairbanks,c=US
o: University of Alaska Fairbanks
description: Preparing Alaska for a brave new yesterday
description: leaf node only
dn: o=University of Colorado at Boulder,c=US
o: University of Colorado at Boulder

DIAGNOSTICS
Exit status is zero if no errors occur. Errors result in a
non-zero exit status and a diagnostic message being written
to standard error.
