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.

       The search results are displayed using an  extended  version  of  LDIF.
       Option -L controls the format of the output.

OPTIONS
       -V[V]  Print  version  info.   If  -VV  is  given, exit after providing
              version info. Otherwise proceed with the specified search

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

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

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

       -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.

       -t[t]  A  single  -t  writes 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
              second -t writes all retrieved values to files.

       -T path
              Write temporary files to directory specified by  path  (default:
              system default tmp directory). The environment variables TMPDIR,
              TMP, or TEMP will override the default path.

       -F prefix
              URL prefix for temporary files.  Default  is  file://path  where
              path  is the system default tmp directory or the value 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.

       -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
              Distinguished  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.

       -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
              children  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.

       -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.

       -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  %
              character,  the  character  should  be  encoded  as \25 (see RFC
              4515).  If file is a single - character, then the lines are read
              from  standard  input.  ldapsearch will exit when the first non-
              successful search result is returned, unless -c is used.

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

       -x     Use simple authentication instead of SASL.

       -D binddn
              Use the Distinguished Name binddn to bind to the LDAP directory.
              For SASL binds, the server is expected to ignore this value.

       -W     Prompt  for  simple  authentication.   This  is  used instead of
              specifying 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
              protocol/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.

       -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>")
                [!]bauthzid           (RFC 3829 authzid control)
                [!]chaining[=<resolve>[/<cont>]]
                [!]manageDSAit
                [!]noop
                ppolicy
                [!]postread[=<attrs>] (a comma-separated attribute list)
                [!]preread[=<attrs>]  (a comma-separated attribute list)
                [!]relax
                sessiontracking[=<username>]
                abandon,cancel,ignore (SIGINT sends abandon/cancel,
                or ignores response; if critical, doesn't wait for SIGINT.
                not really controls)

              Search extensions:
                !dontUseCopy
                [!]domainScope                       (domain scope)
                [!]mv=<filter>                       (matched values filter)
                [!]pr=<size>[/prompt|noprompt]       (paged results/prompt)
                [!]sss=[-]<attr[:OID]>[/[-]<attr[:OID]>...]  (server side sorting)
                [!]subentries[=true|false]           (subentries)
                [!]sync=ro[/<cookie>]                (LDAP Sync refreshOnly)
                        rp[/<cookie>][/<slimit>]     (LDAP Sync refreshAndPersist)
                [!]vlv=<before>/<after>(/<offset>/<count>|:<value>)  (virtual list view)
                [!]deref=derefAttr:attr[,attr[...]][;derefAttr:attr[,attr[...]]]
                [!]<oid>[=:<value>|::<b64value>]

       -o opt[=optparam]

              Specify any ldap.conf(5) option or one of the following:
                nettimeout=<timeout>  (in seconds, or "none" or "max")
                ldif_wrap=<width>     (in columns, or "no" for no wrapping)

       -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.

       -N     Do not use reverse DNS to canonicalize SASL host name.

       -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
              successful.

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 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 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: Naturally Inspiring
           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.
