LDAP::What is the syntax of ldapsearch User Commands ldapsearch(1) NAME ldapsearch - ldap search tool SYNOPSIS ldapsearch [-n] [-u] [-v] [-t] [-A] [-B] [-L] [-R] [- d debuglevel] [-F sep] [-f file] [-D binddn] [-w passwd] [- h ldaphost] [-M authentication] [-p ldapport] [- b searchbase] [-s scope] [-a deref] [ -l timelimit] [ -z sizelimit] filter [attrs...] 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 tem- porary 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 The following options are supported: -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. -a deref Specify how aliases dereferencing is done. The possi- ble 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 SunOS 5.9 Last change: 8 Mar 2004 1 User Commands ldapsearch(1) object for the search. The default is to never dereference aliases. -B Do not suppress display of non-ASCII values. This is useful when dealing with values that appear in alter- nate character sets such as ISO-8859.1. This option is automatically set by the -L option. -b searchbase Use searchbase as the starting point for the search instead of the default. -D binddn Use the distinguished name binddn to bind to the directory. -d debuglevel Set the LDAP debugging level. Useful levels of debug- ging for ldapsearch are: 1 Trace 2 Packets 4 Arguments 32 Filters 128 Access control To request more than one category of debugging infor- mation, add the masks. For example, to request trace and filter information, specify a debuglevel of 33. -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. -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. -h ldaphost Specify an alternate host on which the slapd server is running. SunOS 5.9 Last change: 8 Mar 2004 2 User Commands ldapsearch(1) -L Display search results in a modified format. This option also turns on the -B option, and causes the -F option to be ignored. -l timelimit Wait at most timelimit seconds for a search to com- plete. -M authentication Specifies the authentication mechanism used to bind to the directory. The default authentication method for ldapsearch is simple bind. simple bind sends the password to the server in the clear. The password is subject to snoop- ing if the server is not local. You must use special care when you use this command with the default authentication method. If your server supports the challenge response method CRAM-MD5 authentication method, you can override the default authentication method by using the -M option with CRAM-MD5 as the value for authentication. The bind DN and bind password are mandatory with this option. -n Show what would be done, but do not actually perform the search. Useful in conjunction with -v and -d for debugging. -p ldapport Specify an alternate TCP port where the slapd server is listening. -R Do not automatically follow referrals returned while searching. -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. -t Write retrieved values to a set of temporary files. This is useful for dealing with non-ASCII values such as jpegPhoto or audio. -u Include the user-friendly form of the Distinguished Name (DN) in the output. -v Run in verbose mode, with diagnostics written to stan- dard output. SunOS 5.9 Last change: 8 Mar 2004 3 User Commands ldapsearch(1) -w passwd Use passwd as the password for authentication to the directory. When you use -w passwd to specify the pass- word to be used for authentication, the password is visible to other users of the system by means of the ps command, in script files or in shell history. If you use the ldapsearch command without this option, the command will prompt for the password and read it from standard in. When used without the -w option, the password will not be visible to other users. -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 SunOS 5.9 Last change: 8 Mar 2004 4 User Commands ldapsearch(1) 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 organ- izationName and description attribute values will be retrieved and printed to standard output, resulting in out- put 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. ATTRIBUTES See attributes(5) for a description of the following attri- butes:
