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 user 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.hostname principal registered with your Kerberos  Domain
              Controller(s).

       -t     Write  retrieved  non-printable  values  to  a  set of temporary
              files.  This is useful for dealing with values  containing  non-
              character data 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  second  -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.

       -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 Dis-
              tingished 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  -  charac-
              ter, 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 spec-
              ifying the password on the command line.

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

       -y passwdfile
              Use  complete  contents of passwdfile 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 listen-
              ing.  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
              dereferenced,  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) or none means  no  limit.   A  server  may
              impose  a  maximal  timelimit which only the root user may over-
              ride.

       -z sizelimit
              retrieve at most sizelimit entries for a search.  A sizelimit of
              0  (zero) or none means no limit.  A server may impose a maximal
              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.

       -R realm
              Specify the realm of authentication ID for SASL bind.  The  form
              of the realm 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  suc-
              cessful.


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 "attribute-
       name" part is written.


EXAMPLE

       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 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

           ...


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.
