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.
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
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>]
Specify general options.
General options:
nettimeout=<timeout> (in seconds, or "none" or "max")
ldif-wrap=<width> (in columns, or "no" for no wrapping)
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.
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: 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
...
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.
