DESCRIPTION
ldapsearch is a shell-accessible interface to the ldap_search_ext(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 4515. 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.
The search results are displayed using an extended version of LDIF. Option -L controls
the format of the output.
OPTIONS
-V[V] Print version info. If -VV is given, exit after providing version info. Otherwise
proceed with the specified search
-d debuglevel
Set the LDAP debugging level to debuglevel. ldapsearch must be compiled with
LDAP_DEBUG defined for this option to have any effect.
-n Show what would be done, but don't actually perform the search. Useful for
debugging in conjunction with -v.
-v Run in verbose mode, with many diagnostics written to standard output.
-c Continuous operation mode. Errors are reported, but ldapsearch will continue with
searches. The default is to exit after reporting an error. Only useful in
conjunction with -f.
-u Include the User Friendly Name form of the Distinguished Name (DN) in the output.
-t[t] A single -t writes 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 second -t writes all retrieved values to files.
-T path
Write temporary files to directory specified by path (default: system default tmp
directory). The environment variables TMPDIR, TMP, or TEMP will override the
default path.
-F prefix
URL prefix for temporary files. Default is file://path where path is the system
default tmp directory or the value specified with -T.
-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.
-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 Distinguished 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.
-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 children 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.
-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.
-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 and only occurrence of %s is replaced with a line from file. Any other
occurrence of the the % character in the pattern will be regarded as an error.
Where it is desired that the search filter include a % character, the character
should be encoded as \25 (see RFC 4515). If file is a single - character, then the
lines are read from standard input. ldapsearch will exit when the first non-
successful search result is returned, unless -c is used.
-M[M] Enable manage DSA IT control. -MM makes control critical.
-x Use simple authentication instead of SASL.
-D binddn
Use the Distinguished Name binddn to bind to the LDAP directory. For SASL binds,
the server is expected to ignore this value.
-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.
-H ldapuri
Specify URI(s) referring to the ldap server(s); a list of URI, separated by
whitespace or commas is expected; only the protocol/host/port fields are allowed.
As an exception, if no host/port is specified, but a DN is, the DN is used to look
up the corresponding host(s) using the DNS SRV records, according to RFC 2782. The
DN must be a non-empty sequence of AVAs whose attribute type is "dc" (domain
component), and must be escaped according to RFC 2396.
-P {2|3}
Specify the LDAP protocol version to use.
-e [!]ext[=extparam]
-E [!]ext[=extparam]
Specify general extensions with -e and search extensions with -E. ´!´ indicates
criticality.
General extensions:
[!]assert=<filter> (an RFC 4515 Filter)
!authzid=<authzid> ("dn:<dn>" or "u:<user>")
[!]bauthzid (RFC 3829 authzid control)
[!]chaining[=<resolve>[/<cont>]]
[!]manageDSAit
[!]noop
ppolicy
[!]postread[=<attrs>] (a comma-separated attribute list)
[!]preread[=<attrs>] (a comma-separated attribute list)
[!]relax
sessiontracking[=<username>]
abandon,cancel,ignore (SIGINT sends abandon/cancel,
or ignores response; if critical, doesn't wait for SIGINT.
not really controls)
Search extensions:
!dontUseCopy
[!]domainScope (domain scope)
[!]mv=<filter> (matched values filter)
[!]pr=<size>[/prompt|noprompt] (paged results/prompt)
[!]sss=[-]<attr[:OID]>[/[-]<attr[:OID]>...] (server side sorting)
[!]subentries[=true|false] (subentries)
[!]sync=ro[/<cookie>] (LDAP Sync refreshOnly)
rp[/<cookie>][/<slimit>] (LDAP Sync refreshAndPersist)
[!]vlv=<before>/<after>(/<offset>/<count>|:<value>) (virtual list view)
[!]deref=derefAttr:attr[,attr[...]][;derefAttr:attr[,attr[...]]]
[!]<oid>[=:<value>|::<b64value>]
-o opt[=optparam]
Specify any ldap.conf(5) option or one of the following:
nettimeout=<timeout> (in seconds, or "none" or "max")
ldif_wrap=<width> (in columns, or "no" for no wrapping)
-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.
-N Do not use reverse DNS to canonicalize SASL host name.
-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 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 organization name
(o) 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: Naturally Inspiring
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.
