DESCRIPTION

ldapsearch opens a connection to an LDAP server, binds, and performs a search using the filter filter.

If ldapsearch finds one or more entries, the attributes specified by attrs are retrieved and the entries and values are printed to standard output. If no attrs are listed, all attributes are returned.

Output Format

If one or more entries are found, each entry is written to standard output in the form:

Distinguished Name (DN)
    User Friendly Name (if the -u option is used)
    attributename=value
    attributename=value
    attributename=value
    ...

Multiple entries are separated with a single blank line. If the -F option is used to specify a different separator character, this character will be used instead of the `=' character. If the -t option is used, the name of a temporary file is returned in place of the actual value. If the -A option is given, only the "attributename" is returned and not the attribute value.

OPTIONS

-n

Show what would be done, but don't actually perform the search. Useful in conjunction with -v and -d for debugging.

-u

Include the user-friendly form of the Distinguished Name (DN) in the output.

-v

Run in verbose mode, with diagnostics written to standard output.

-t

Write retrieved values to a set of temporary files. This is useful for dealing with non-ASCII values such as jpegPhoto or audio.

-A

Retrieve attributes only (no values). This is useful when you just want to see whether an attribute is present in an entry and are not interested in the specific value.

-B

Do not suppress display of non-ASCII values. This is useful when dealing with values that appear in alternate character sets such as ISO-8859.1. This option is automatically set by the -L option.

-L

Display search results in a modified format. This option also turns on the -B option, and causes the -F option to be ignored.

-R

Do not automatically follow referrals returned while searching.

-F sep

Use sep as the field separator between attribute names and values. The default separator is `='. If -L option has been specified, this option is ignored.

-d debuglevel

Set the LDAP debugging level. Useful levels of debugging for ldapmodify and ldapadd are:

1: Trace
2: Packets
4: Arguments
32: Filters
128: Access control

To request more than one category of debugging information, add the masks. For example, to request trace and filter information, specify a debuglevel of 33.

-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.

-D binddn

Use the distinguished name binddn to bind to the directory.

-w passwd

Use passwd as the password for authentication to the directory.

-h ldaphost

Specify an alternate host on which the slapd server is running.

-M authentication

Specifies the authentication mechanism used to bind to the directory. This option can have the value CRAM-MD5. The bind DN and bind password are mandatory with this option.

-p ldapport

Specify an alternate TCP port where the slapd server is listening.

-b searchbase

Use searchbase as the starting point for the search instead of the default.

-s scope

Specify the scope of the search. The possible values of scope are base, one, or sub to specify respectively a base object, one-level, or subtree search. The default is sub.

-a deref

Specify how aliases dereferencing is done. The possible values for deref are never, always, search, or find to specify respectively that aliases are never dereferenced, always dereferenced, dereferenced when searching, or dereferenced only when finding 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.

-z sizelimit

Retrieve at most sizelimit entries for a search to complete.

EXAMPLES

Example 1 Performing a Subtree Search

The following command performs a subtree search (using the default search base) for entries with a commonName of "mark smith". The commonName and telephoneNumber values will be retrieved and printed to standard output.

example% ldapsearch "cn=mark smith" cn telephoneNumber

The output looks something like this:

cn=Mark D Smith, ou=Sales, ou=Atlanta, ou=People, o=XYZ, c=US
cn=Mark Smith
cn=Mark David Smith
cn=Mark D Smith 1
cn=Mark D Smith
telephoneNumber=+1 123 456-7890
cn=Mark C Smith, ou=Distribution, ou=Atlanta, ou=People, o=XYZ, c=US
cn=Mark Smith
cn=Mark C Smith 1
cn=Mark C Smith
telephoneNumber=+1 123 456-9999

Example 2 Performing a Subtree Search Using the Default Search Base

The following command performs a subtree search using the default search base for entries with user id of "mcs". 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.

example%ldapsearch -u -t "uid=mcs" jpegPhoto audio

The output might look like this if one entry with one value for each of the requested attributes is found:

cn=Mark C Smith, ou=Distribution, ou=Atlanta, ou=People, o=XYZ, c=US
Mark C Smith, Distribution, Atlanta, People, XYZ, US
audio=/tmp/ldapsearch-audio-a19924
jpegPhoto=/tmp/ldapsearch-jpegPhoto-a19924

Example 3 Performing a One Level Search

The following command performs a one-level search at the c=US level for all organizations whose organizationName begins with XY.

example% ldapsearch -L -s one -b "c=US" "o=XY*" o description

Search results are displayed in the LDIF format. The organizationName and description attribute values will be retrieved and printed to standard output, resulting in output similar to this:

dn: o=XYZ, c=US
o: XYZ
description: XYZ Corporation
dn: o="XY Trading Company", c=US
o: XY Trading Company
description: Import and export specialists

dn: o=XYInternational, c=US
o: XYInternational
o: XYI
o: XY International

EXIT STATUS

The following exit values are returned:

0: Successful completion.
>0: An error occurred. A diagnostic message is written to standard error.
