ldapsearch - LDAP search tool
SYNOPSIS

[-z sizelimit] [-O security-properties] [-I] [-Q] [-U authcid]
[-R realm] [-x] [-X authzid] [-Y mech] [-Z[Z]] filter [attrs...]
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.
-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 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 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 Distin-
guished 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 - charac-
ter, 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 spec-
ifying 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.
-H ldapuri
Specify URI(s) referring to the ldap server(s); only the proto-
col/host/port fields are allowed; a list of URI, separated by
whitespace or commas is expected.
-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 listen-
ing. Deprecated in favor of -H.
-b searchbase
Use searchbase as the starting point for the search instead of
the default.
-s base|one|sub|children
Specify the scope of the search to be one of base, one, sub, or
children to specify a base object, one-level, subtree, or chil-
dren search. The default is sub. Note: children scope requires
LDAPv3 subordinate feature extension.
-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 complete. A
timelimit of 0 (zero) or none means no limit. A timelimit of
max means the maximum integer allowable by the protocol. 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 sizelimit of max means the
maximum integer allowable by the protocol. 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 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 suc-
cessful.
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 "attribute-
name" 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
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
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.
