ldapsearch is a shell-accessible interface to the ldap_search_ext(3) library call.
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

have any effect.

Use complete contents of

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.

If one or more entries are found, each entry is written to standard output in LDAP Data Interchange Format or ldif(5):

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
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
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

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.
