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 Distinguished 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 non-printable values to a set of temporary files. This is
useful for dealing with values containing non-character data such as jpeg-
Photo 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 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 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 authentica-
tion.
-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. Depre-
cated 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 locat-
ing 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 complete. A timelimit of 0
(zero) or none means no 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) or
none means no 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 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 authentication. If it’s not speci-
fied, 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 and other parameters
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
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 organiza-
tion 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
description: No personnel information
description: Institution of education and research
dn: o=University of Colorado at Denver,c=US
o: University of Colorado at Denver
o: UCD
o: CU/Denver
o: CU-Denver
description: Institute for Higher Learning and Research
dn: o=University of Florida,c=US
o: University of Florida
o: UFl
description: Warper of young minds
...
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.
