DESCRIPTION

       ldapsearch is a shell-accessible interface to the ldap_search(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 2254.  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 attributes are returned.  If only 1.1 is listed, no
       attributes will be returned.

OPTIONS

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

       -u     Include the User Friendly Name form of the Distinguished Name (DN) in the output.

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

       -k     Use Kerberos IV authentication instead of simple authentication.	It is assumed that  you  already  have	a  valid  ticket  granting
	      ticket.  ldapsearch must be compiled with Kerberos support for this option to have any effect.

       -K     Same  as	-k, but only does step 1 of the Kerberos IV bind.  This is useful when connecting to a slapd and there is no x500dsa.host-
	      name principal registered with your Kerberos Domain Controller(s).

       -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 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 sec-
	      ond -L disables comments.  A third -L disables printing of the LDIF version.  The default is to use an extended version of LDIF.

       -M[M]  Enable manage DSA IT control.  -MM makes control critical.

       -C     Automatically chase referrals.

       -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 Distingished 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.

       -d debuglevel
	      Set the LDAP debugging level to debuglevel.  ldapsearch must be compiled with LDAP_DEBUG defined for this option to have any effect.

       -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.

       -x     Use simple authentication instead of SASL.

       -D binddn
	      Use the Distinguished Name binddn to bind to the LDAP directory.

       -W     Prompt for simple authentication.  This is used instead of specifying the password on the command line.

       -w bindpasswd
	      Use bindpasswd as the password for simple authentication.

       -H ldapuri
	      Specify URI(s) referring to the ldap server(s).

       -h ldaphost
	      Specify an alternate host on which the ldap server is running.  Deprecated in favor of -H.

       -p ldapport
	      Specify an alternate TCP port where the ldap server is listening.  Deprecated in favor of -H.

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

       -s base|one|sub
	      Specify  the scope of the search to be one of base, one, or sub to specify a base object, one-level, or subtree search.  The default
	      is sub.

       -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 deref-
	      erenced,	always	dereferenced, dereferenced when searching, or dereferenced only when locating the base object for the search.  The
	      default is to never dereference aliases.

       -P 2|3 Specify the LDAP protocol version to use.

       -l timelimit
	      wait at most timelimit seconds for a search to complete.	A timelimit of 0 (zero) removes the ldap.conf limit.  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) removes the ldap.conf limit.  A server may impose a maxi-
	      mal sizelimit which only the root user may override.

       -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.

       -U authcid
	      Specify the authentication ID for SASL bind. The form of the ID 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  success-
	      ful.

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 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 begins with University.  The organiza-
       tion 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

	   etc....

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.
