.SH DESCRIPTION
.I ldapsearch
is a shell-accessible interface to the
.BR ldap_search (3)
library call.
.LP
.B ldapsearch
opens a connection to an LDAP server, binds, and performs a search
using the filter \fIfilter\fP.  The \fIfilter\fP should conform to
the string representation for LDAP filters as defined in RFC 1558.
.LP
If
.B ldapsearch
finds one or more entries, the attributes specified by
\fIattrs\fP are retrieved and the entries and values are printed to
standard output.  If no \fIattrs\fP are listed, all attributes are
returned.
.SH OPTIONS
.TP
.B \-n
Show what would be done, but don't actually perform the search.  Useful for
debugging in conjunction with -v.
.TP
.B \-u
Include the User Friendly form of the Distinguished Name (DN) in the output
.TP
.B \-v
Run in verbose mode, with many diagnostics written to standard output
.TP
.B \-k
Use Kerberos authentication instead of simple authentication.  It is
assumed that you already have a valid ticket granting ticket.
.B ldapsearch
must be compiled with KERBEROS defined for this option to have any effect.
.TP
.B \-K
Same as \-k, but only does step 1 of the kerberos bind.  This is useful
when connecting to a slapd and there is no x500dsa.hostname principal
registered with your kerberos servers.
.TP
.B \-t
Write retrieved values to a set of temporary files.  This is useful for
dealing with non-ASCII values such as jpegPhoto or audio.
.TP
.B \-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.
.TP
.B \-B
Do not suppress display of non-ascii values.  This is useful when
dealing with values that appear in alternate characters sets such as
ISO-8859.1.  This option is implied by -L (see below).
.TP
.B \-L
Display search results in
.BR ldif (5)
format.  This option also turns on the -B option, and causes the -F option
to be ignored.
.TP
.B \-R
Do not automatically follow referrals returned while searching.
.B ldapsearch
must be compiled with LDAP_REFERRALS defined for referrals to be
automatically followed by default, and for this option to have any effect.
.TP
.B \-F sep
Use \fIsep\fP as the field separator between attribute names and values.
The default separator is `=', unless the -L flag has been specified, in
which case this option is ignored.
.TP
.B \-S attribute
Sort the entries returned based on \fIattribute\fP. The default is not
to sort entries returned.  If \fIattribute\fP is a zero-length string (""),
the entries are sorted by the components of their Distingished Name.  See
.BR ldap_sort (3)
for more details. Note that
.B ldapsearch
normally prints out entries as it receives them. The use of the
.B \-S
option defeats this behavior, causing all entries to be retrieved,
then sorted, then printed.
.TP
.B \-d debuglevel
Set the LDAP debugging level to \fIdebuglevel\fP.
.B ldapsearch
must be compiled with LDAP_DEBUG defined for this option to have any effect.
.TP
.B \-f file
Read a series of lines from \fIfile\fP, performing one LDAP search for
each line.  In this case, the \fIfilter\fP given on the command line
is treated as a pattern where the first occurrence of \fB%s\fP is
replaced with a line from \fIfile\fP.  If \fIfile\fP is a single \fI-\fP
character, then the lines are read from standard input.
.TP
.B \-D binddn
Use \fIbinddn\fP to bind to the LDAP directory. \fIbinddn\fP should be
a string-represented DN as defined in RFC 1779.
.TP
.B \-w bindpasswd
Use \fIbindpasswd\fP as the password for simple authentication.
.TP
.B \-h ldaphost
Specify an alternate host on which the ldap server is running.
.TP
.B \-p ldapport
Specify an alternate TCP port where the ldap server is listening.
.TP
.B \-b searchbase
Use \fIsearchbase\fP as the starting point for the search instead of
the default.
.TP
.B \-s scope
Specify the scope of the search.  \fIscope\fP should be one of
.B base,
.B one,
or
.B sub
to specify a base object, one-level, or subtree search.  The default
is
.BR sub .
.TP
.B \-a deref
Specify how aliases dereferencing is done.  \fIderef\fP should be one of
.B never,
.B always,
.B search,
or
.B 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.
.TP
.B \-l timelimit
wait at most \fItimelimit\fP seconds for a search to complete.
.TP
.B \-z sizelimit
retrieve at most \fIsizelimit\fP entries for a search.
.SH OUTPUT FORMAT
If one or more entries are found, each entry is written to standard output
in the form:
.LP
.nf
    Distinguished Name (DN)
    User Friendly Name (this line present only if the -u option is used)
    attributename=value
    attributename=value
    attributename=value
    ...
.fi
.LP
Multiple entries are separated with a single blank line.  If the -F option
is used to specify a separator character, it will be used instead of the
`=' character.  If the -t option is used, the name of a temporary file
is used in place of the actual value.  If the -A option
is given, only the "attributename" part is written.
.SH EXAMPLE
The following command:
.LP
.nf
    ldapsearch "cn=mark smith" cn telephoneNumber
.fi
.LP
will perform 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.
The output might look something like this if two entries are found:
.LP
.nf
cn=Mark D Smith, ou="College of Literature, Science, and the Arts", ou=Students, ou=People, o=University of Michigan, c=US
cn=Mark Smith
cn=Mark David Smith
cn=Mark D Smith 1
cn=Mark D Smith
telephoneNumber=+1 313 930-9489

cn=Mark C Smith, ou=Information Technology Division, ou=Faculty and Staff, ou=People, o=University of Michigan, c=US
cn=Mark Smith
cn=Mark C Smith 1
cn=Mark C Smith
telephoneNumber=+1 313 764-2277
.fi
.LP
The command:
.LP
.nf
    ldapsearch -u -t "uid=mcs" jpegPhoto audio
.fi
.LP
will perform 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.  The
output might look like this if one entry with one value for each of the
requested attributes is found:
.LP
.nf
cn=Mark C Smith, ou=Information Technology Division, ou=Faculty and Staff, ou=People, o=University of Michigan, c=US
Mark C Smith, Information Technology Division, Faculty and Staff, People, University of Michigan, US
audio=/tmp/ldapsearch-audio-a19924
jpegPhoto=/tmp/ldapsearch-jpegPhoto-a19924
.fi
.LP
This command:
.LP
.nf
    ldapsearch -L -s one -b "c=US" "o=university*" o description
.fi
.LP
will perform a one-level search at the c=US level for all organizations
whose organizationName begins with \fBuniversity\fP.  Search results
will be displayed in the LDIF format.
The organizationName and description attribute values will be retrieved
and printed to standard output, resulting in output similar to this:
.LP
.nf
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....
.fi
