.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 search filters as defined in RFC 2254.
.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.  If * is listed, all user attributes are returned.
If + is listed, all operational attributes are returned.
If only 1.1 is listed, no attributes are listed.
.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 Name 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 support 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 \-L
Search results are display in LDAP Data Interchange Format detailed in
.BR 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.
.TP
.B \-M[M]
Enable manage DSA IT control.
.B \-MM
makes control critical.
.TP
.B \-C
Automatically chase referrals.
.TP
.BI \-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
.BI \-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
.BI \-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 \-x 
Use simple authentication instead of SASL.
.TP
.BI \-D \ binddn
Use the Distinguished Name \fIbinddn\fP to bind to the LDAP directory.
.TP
.B \-W
Prompt for simple authentication.
This is used instead of specifying the password on the command line.
.TP
.BI \-w \ bindpasswd
Use \fIbindpasswd\fP as the password for simple authentication.
.TP
.BI \-H \ ldapuri
Specify URI(s) referring to the ldap server(s).
.TP
.BI \-h \ ldaphost
Specify an alternate host on which the ldap server is running.
Deprecated in favor of -H.
.TP
.BI \-p \ ldapport
Specify an alternate TCP port where the ldap server is listening.
Deprecated in favor of -H.
.TP
.BI \-b \ searchbase
Use \fIsearchbase\fP as the starting point for the search instead of
the default.
.TP
.BI \-s \ base\fR\||\|\fIone\fR\||\|\fIsub
Specify the scope of the search to be one of
.IR base ,
.IR one ,
or
.I sub
to specify a base object, one-level, or subtree search.  The default
is
.IR sub .
.TP
.BI \-a \ never\fR\||\|\fIalways\fR\||\|\fIsearch\fR\||\|\fIfind
Specify how aliases dereferencing is done.  Should be one of
.IR never ,
.IR always ,
.IR search ,
or
.I 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
.BI \-P \ 2\fR\||\|\fI3
Specify the LDAP protocol version to use.
.TP
.BI \-l \ timelimit
wait at most \fItimelimit\fP seconds for a search to complete.  A
timelimit of
.I 0
(zero) removes the
.B ldap.conf
limit.
A server may impose a maximal timelimit which only
the root user may override.
.TP
.BI \-z \ sizelimit
retrieve at most \fIsizelimit\fP entries for a search.  A sizelimit
of 
.I 0
(zero) removes the 
.B ldap.conf
limit.
A server may impose a maximal sizelimit which only
the root user may override.
.TP
.BI \-O \ security-properties
Specify SASL security properties.
.TP
.B \-I
Enable SASL Interactive mode.  Always prompt.  Default is to prompt
only as needed.
.TP
.B \-Q
Enable SASL Quiet mode.  Never prompt.
.TP
.BI \-U \ username
Specify the username for SASL bind. The syntax of the username depends on the
actual SASL mechanism used.
.TP
.TP
.BI \-X \ authzid
Specify the requested authorization ID for SASL bind.
.I authzid
must be one of the following formats:
.B dn:\c
.I <distinguished name>
or
.B u:\c
.I <username>
.TP
.BI \-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.
.TP
.B \-Z[Z]
Issue StartTLS (Transport Layer Security) extended operation. If you use
.B \-ZZ\c
, the command will require the operation to be successful.
.SH OUTPUT FORMAT
If one or more entries are found, each entry is written to standard
output in LDAP Data Interchange Format or
.BR ldif (5):
.LP
.nf
	version: 1

	# bjensen, example, net
	dn: uid=bjensen, dc=example, dc=net
	objectClass: person
	objectClass: dcObject
	uid: bjensen
	cn: Barbara Jensen
	sn: Jensen
    ...
.fi
.LP
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.
.SH EXAMPLE
The following command:
.LP
.nf
    ldapsearch -LLL "(sn=smith)" cn sn telephoneNumber
.fi
.LP
will perform a subtree search (using the default search base defined
in
.BR 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:
.LP
.nf
    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
.fi
.LP
The command:
.LP
.nf
    ldapsearch -LLL -u -t "(uid=xyz)" jpegPhoto audio
.fi
.LP
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:
.LP
.nf
    dn: uid=xyz, dc=example, dc=com
    ufn: xyz, example, com
    audio:< file::/tmp/ldapsearch-audio-a19924
    jpegPhoto:< file::=/tmp/ldapsearch-jpegPhoto-a19924
.fi
.LP
This command:
.LP
.nf
    ldapsearch -LLL -s one -b "c=US" "(o=University*)" o description
.fi
.LP
will perform a one-level search at the c=US level for all entries
whose organization name (o) begins begins with \fBUniversity\fP.
The organization name 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
