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, the attributes
specified by 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 Distin
guished 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 compiled 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 regis
tered 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.
critical.
-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 fil
ter given on the command line is treated as a pat
tern where the first occurrence of %s is replaced
with a line from file. If file is a single - char
acter, 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 authentica
tion.
-y passwdfile
Use complete contents of passwdfile as the password
for simple authentication.
-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
be one of never, always, search, or find to specify
that aliases are never dereferenced, always deref
erenced, dereferenced when searching, or derefer
enced 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
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 proxy 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 authenti
cation. 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.

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 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
contains 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

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.
