MUTT_LDAP_QUERY(1)     User Contributed Perl Documentation    MUTT_LDAP_QUERY(1)

NAME
     mutt_ldap_query - Query LDAP server for Mutt mail-reader

SYNOPSIS
     mutt_ldap_query.pl [options] <name_to_query> [[<other_name_to_query>] ...]

OPTIONS
     --config=config_file or -c config_file
	     specify an alternate resource file other than the system ones
	     (/usr/local/etc/lbdb_ldap.rc or /usr/local/etc/mutt_ldap_query.rc)
	     or default personal ones ($HOME/.lbdb/ldap.rc or
	     $HOME/.mutt_ldap_query.rc).

     --server=ldap_server or -ls ldap_server
	     hostname of your ldap server.  You can also use an
	     ldap://foo[:port] or ldaps://foo[:port] URL here to talk to differ-
	     ent ports or SSL encrypted servers.  Or use
	     ldapi://%2fvar%2flib%2fldap_sock to access an ldap server via a
	     socket (use %2f as as replacement for a slash in the file name).

     --search_base=ldap_search_base or -sb ldap_search_base
	     use <search_base> as the starting point for the search instead of
	     the default.

     --search_fields=ldap_search_fields or -sf ldap_search_fields
	     list of the fields on which the query will be performed.

     --expected_answers=ldap_expected_answers or -ea ldap_expected_answers
	     list of the fields expected as the answer of the ldap server that
	     will be used for composing the output of the script.

     --format_email=result_format_email or -fe result_format_email
	     format to be used for composing the email output result. It has to
	     be based on the expected ldap server answers and can use variable
	     containers of the form ${variable} where variable belongs to the
	     <ldap_expected_answers> set.

     --format_realname=result_format_realname or -fr result_format_realname
	     format to be used for composing the realname output result. It has
	     to be based on the expected ldap server answers and can use vari-
	     able containers of the form ${variable} where variable belongs to
	     the <ldap_expected_answers> set.

     --format_comment=result_format_comment or -fc result_format_comment
	     format to be used for composing the comment output result. It has
	     to be based on the expected ldap server answers and can use vari-
	     able containers of the form ${variable} where variable belongs to
	     the <ldap_expected_answers> set.

     --bind_dn=bind_distinguished_name or -bd bind_distinguished_name
	     the destinguished name of the user who binds to the LDAP server.
	     Leave it empty for an anonmyous bind.

     --bind_password=secret or -bp secret
	     the bind password for binding to the LDAP server.	Leave it empty
	     for an anonmyous bind.

     --tls=1 or --tls=0
	     enable or disable transport layer security (TLS).

     --sasl_mech=mechanism or -sm mechanism
	     the SASL mechanism, for example GSSAPI (empty string to turn off).

     --nickname=ldap_server_nickname or -n ldap_server_nickname
	     shortcut for avoiding to use all the previous options by using the
	     script builtin or alternate config file table of common servers and
	     associated options.  All the required parameters are then derived
	     by performing a <lbdb_server_nickname> lookup.

     --debug or -d
	     turn on debugging messages.

     --help or -? or -h or --man or -m
	     generates this help message.

     --ignorant or -i
	     ignorant mode: search using wildcard for *name_to_query* (requires
	     a longer processing from LDAP server but is quite convenient :).

     --lbdb_output or -l
	     suppress number of matches output (suited for interfacing with lit-
	     tle brother database http://www.spinnaker.de/lbdb/).

     --version or -v
	     show the version.

DESCRIPTION
     mutt_ldap_query performs ldap queries using either ldapsearch command or
     the perl-ldap module and it outputs the required formatted data for feeding
     mutt when using its "External Address Query" feature.

     The output of the script consists in 3 fields separated with tabs: the
     email address, the name of the person and a comment.

INTERFACING WITH MUTT
     This perl script can be interfaced with mutt by defining in your .muttrc:

	 set query_command = "mutt_ldap_query.pl %s"

     Multiple requests are supported: the "Q" command of mutt accepts as argu-
     ment a list of queries (e.g. "Gosse de\ Courville").

     Alternatively mutt_ldap_query can be interfaced with the more generic lit-
     tle brother database query program (http://www.spinnaker.de/lbdb/) using:

	 set query_command = "lbdbq %s"

     and by specifying in your ~/.lbdb/lbdbrc file another method of query just
     adding to the METHODS variable the m_ldap module e.g.:

	 METHODS='m_inmail m_passwd m_ldap m_muttalias m_finger'

     and the right path to access m_ldap in MODULES_PATH, e.g. if you moved
     m_ldap in ~/.lbdb/modules:

	 MODULES_PATH="/usr/local/lib $HOME/.lbdb/modules"

     Just make sure to use the correct path for calling mutt_ldap_query in the
     m_ldap script.

RESOURCE FILE FORMAT
     mutt_ldap_query is now fully customizable using an external resource file.
     By default mutt_ldap_query parses the system definition file located gener-
     ally at /etc/mutt_ldap_query.rc or /usr/local/etc/mutt_ldap_query.rc and
     also the user one: $HOME/.mutt_ldap_query.rc.

     Instead of using command line options, the user can redefine all the vari-
     ables using the resource file by two manners in order to match his site
     configuration.  A file example is provided below:

	 # The format of each entry of the ldap server database is the following:
	 # LDAP_NICKNAME => ['LDAP_SERVER',
	 #		     'LDAP_SEARCH_BASE',
	 #		     'LDAP_SEARCH_FIELDS',
	 #		     'LDAP_EXPECTED_ANSWERS',
	 #		     'LDAP_RESULT_EMAIL',
	 #		     'LDAP_RESULT_REALNAME',
	 #		     'LDAP_RESULT_COMMENT'],

	 # a practical illustrating example being:
	 #  debian   => ['db.debian.org',
	 #		 'ou=users,dc=debian,dc=org',
	 #		 'uid cn sn ircnick',
	 #		 'uid cn sn ircnick',
	 #		 '${uid}@debian.org',
	 #		 '${cn} ${sn}',
	 #		 '${ircnick}'],
	 # the output of the query will be then:
	 # ${uid}@debian.org\t${cn} ${sn}\t${ircnick} (i.e.: email name comment)

	 # warning this database will erase default script builtin
	 %ldap_server_db = (
	   'four11'	     => ['ldap.four11.com',
				 'c=US',
				 'givenname sn cn mail',
				 'givenname cn sn mail o',
				 '${mail}',
				 '${givenname} ${sn}',
				 '${o}' ],
	   'infospace'	     => ['ldap.infospace.com',
				 'c=US',
				 'givenname sn cn mail',
				 'givenname cn sn mail o',
				 '${mail}',
				 '${givenname} ${sn}',
				 '${o}' ],
	   'whowhere'	     => ['ldap.whowhere.com',
				 'c=US',
				 'givenname sn cn mail',
				 'givenname cn sn mail o',
				 '${mail}',
				 '${givenname} ${sn}',
				 '${o}' ],
	   'bigfoot'	     => ['ldap.bigfoot.com',
				 'c=US',
				 'givenname sn cn mail'
				, 'givenname cn sn mail o'
				, '${mail}'
				, '${givenname} ${sn}',
				 '${o}' ],
	   'switchboard'     => ['ldap.switchboard.com',
				 'c=US',
				 'givenname sn cn mail'
				, 'givenname cn sn mail o',
				 '${mail}',
				 '${givenname} ${sn}',
				 '${o}' ],
	   'infospacebiz'    => ['ldapbiz.infospace.com',
				 'c=US',
				 'givenname sn cn mail',
				 'givenname cn sn mail o',
				 '${mail}',
				 '${givenname} ${sn}',
				 '${o}' ],
	 );

	 # hostname of your ldap server
	 $ldap_server = 'ldap.four11.com';
	 # ldap base search
	 $search_base = 'c=US';
	 # list of the fields that will be used for the query
	 $ldap_search_fields = 'givenname sn cn mail';
	 # list of the fields that will be used for composing the answer
	 $ldap_expected_answers = 'givenname sn cn mail o';
	 # format of the email result based on the expected answers of the ldap query
	 $ldap_result_email = '${mail}';
	 # format of the realname result based on the expected answers of the ldap query
	 $ldap_result_realname = '${givenname} ${sn}';
	 # format of the comment result based on the expected answers of the ldap query
	 $ldap_result_comment = '(${o})';

EXAMPLES OF QUERIES
	 mutt_ldap_query.pl --ldap_server='ldap.mot.com' \
	    --search_base='ou=employees, o=Motorola,c=US' \
	    --ldap_search_fields='commonName gn sn cn uid' \
	    --ldap_expected_answers='gn sn preferredRfc822Recipient ou c telephonenumber' \
	    --ldap_result_email='${preferredRfc822Recipient}' \
	    --ldap_result_realname='${gn} ${sn}' \
	    --ldap_result_comment='(${telephonenumber}) ${ou} ${c}' \
	    Gosse de\ Courville

     performs a query using the ldap server ldap.mot.com using the following
     searching base 'ou=employees, o=Motorola,c=US' and performing a search on
     the fields 'commonName gn sn cn uid' for 'Gosse' and then "de Courville"
     looking for the following answers 'gn sn preferredRfc822Recipient ou c
     telephonenumber'. Based on this answers, mutt_ldap_query will return a list
     of entries identified of the form:

       <${preferredRfc822Recipient}>\t${gn} ${sn}\t(${telephonenumber}) ${ou} ${c}

     where ${} variables should be considered as containers that are replaced by
     the results of the query. The previous query can be greatly simplified by
     using the ldap server mini database feature of the resource file introduc-
     ing for example a nickname.

	 mutt_ldap_query.pl --ldap_server_nickname='motorola' Gosse de\ Courville

     When not sure of the full name (i.e. it should contain Courville) the igno-
     rant mode is useful since the query will be performed using wildcards, i.e.
     *Courville* in the following case:

	 mutt_ldap_query.pl --ignorant Courville

WHERE TO GET IT
     The latest version can be retrieved at
       ftp://ftp.mutt.org/pub/mutt/contrib or
       http://www.courville.org/

     Note that now the script is integrated in the latest version of the little
     brother database available at http://www.spinnaker.de/lbdb/.  It is thus
     easier to use through this standard package than to hand customize it to
     fit your system/distribution needs.
