DESCRIPTION
       ldapsearch is a shell-accessible interface  to  the  ldap_search_ext(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 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.

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

       -c     Continuous  operation  mode. Errors are reported, but ldapsearch
              will continue with  searches.  The  default  is  to  exit  after
              reporting an error.  Only useful in conjunction with -f.

       -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.

       -t[t]  A  single  -t  writes retrieved non-printable values to a set of
              temporary files.  This is useful for dealing  with  values  con-
              taining  non-character data such as jpegPhoto or audio. A second
              -t writes all retrieved values to files.

       -T path
              Write temporary files to directory specified by  path  (default:
              /var/tmp/)

       -F prefix
              URL  prefix  for temporary files.  Default is file://path/ where
              path is /var/tmp/ or specified with -T.

       -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  Distin-
              guished  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 and only  occurrence  of
              %s  is  replaced with a line from file.  Any other occurrence of
              the the % character in the pattern will be regarded as an error.
              Where  it  is desired that the search filter include a % charac-
              ter, the character should be encoded as \25 (see RFC 4515).   If
              file is a single - character, then the lines are read from stan-
              dard input.  ldapsearch will exit when the first  non-successful
              search result is returned, unless -c is used.

       -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); a list  of  URI,
              separated  by  whitespace or commas is expected; only the proto-
              col/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.

       -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|children
              Specify the scope of the search to be one of base, one, sub,  or
              children  to specify a base object, one-level, subtree, or chil-
              dren search.  The default is sub.  Note: children scope requires
              LDAPv3 subordinate feature extension.

       -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.

       -e [!]ext[=extparam]

       -E [!]ext[=extparam]

              Specify  general  extensions  with -e and search extensions with
              -E.  '!' indicates criticality.

              General extensions:
                [!]assert=<filter>   (an RFC 4515 Filter)
                [!]authzid=<authzid> ("dn:<dn>" or "u:<user>")
                [!]manageDSAit
                [!]noop
                ppolicy
                [!]postread[=<attrs>]        (a comma-separated attribute list)
                [!]preread[=<attrs>] (a comma-separated attribute list)
                abandon, cancel (SIGINT sends abandon/cancel; not really controls)

              Search extensions:
                [!]domainScope                               (domain scope)
                [!]mv=<filter>                               (matched values filter)
                [!]pr=<size>[/prompt|noprompt]       (paged results/prompt)
                [!]subentries[=true|false]           (subentries)
                [!]sync=ro[/<cookie>]                        (LDAP Sync refreshOnly)
                        rp[/<cookie>][/<slimit>]     (LDAP Sync refreshAndPersist)

       -l timelimit
              wait at most timelimit seconds for  a  search  to  complete.   A
              timelimit  of  0  (zero) or none means no limit.  A timelimit of
              max means the maximum integer  allowable  by  the  protocol.   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)  or none means no limit.  A sizelimit of max means the
              maximum integer allowable by the protocol.  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.
