.SH DESCRIPTION
|
|
These functions provide a standard way to access LDAP entry display
|
|
templates. Entry display templates provide a standard way for LDAP
|
|
applications to display directory entries. The general idea is that it
|
|
is possible to map the list of object class values present in an entry
|
|
to an appropriate display template. Display templates are defined in a
|
|
configuration file (see ldaptemplates.conf(5)). Each display template
|
|
contains a pre-determined list of items, where each item generally
|
|
corresponds to an attribute to be displayed. The items contain
|
|
information and flags that the caller can use to display the attribute and
|
|
values in a reasonable fashion. Each item has a syntaxid, which are
|
|
described in the SYNTAX IDS section below. The ldap_entry2text(3)
|
|
routines use the display template functions and produce text output.
|
|
.LP
|
|
ldap_init_templates() reads a sequence of templates from a valid LDAP
|
|
template configuration file (see ldaptemplates.conf(5))
|
|
.I Zero
|
|
is returned upon success, and
|
|
.I tmpllistp
|
|
is set to point to a list of templates. Each member of the list is an
|
|
ldap_disptmpl structure (defined below in the DISPTMPL STRUCTURE ELEMENTS
|
|
section).
|
|
.LP
|
|
.LP
|
|
ldap_init_templates_buf() reads a sequence of templates from
|
|
.I buf
|
|
(whose size is
|
|
.I buflen).
|
|
.I buf
|
|
should point to the data in the format defined for an LDAP template
|
|
configuration file (see ldaptemplates.conf(5))
|
|
.I Zero
|
|
is returned upon success, and
|
|
.I tmpllistp
|
|
is set to point to a list of templates.
|
|
.LP
|
|
The
|
|
.B LDAP_SET_DISPTMPL_APPDATA()
|
|
macro is used to set the value of the dt_appdata field in an ldap_disptmpl
|
|
structure. This field is reserved for the calling application to use; it
|
|
is not used internally.
|
|
.LP
|
|
The
|
|
.B LDAP_GET_DISPTMPL_APPDATA()
|
|
macro is used to retrieve the value in the dt_appdata field.
|
|
.LP
|
|
The
|
|
.B LDAP_IS_DISPTMPL_OPTION_SET()
|
|
macro is used to test a ldap_disptmpl structure for the existence of a
|
|
template option. The options currently defined are:
|
|
.B LDAP_DTMPL_OPT_ADDABLE
|
|
(it is appropriate to allow entries of this type to be added),
|
|
.B LDAP_DTMPL_OPT_ALLOWMODRDN
|
|
(it is appropriate to offer the "modify rdn" operation),
|
|
.B LDAP_DTMPL_OPT_ALTVIEW
|
|
(this template is merely an alternate view of another template, typically
|
|
used for templates pointed to be an LDAP_SYN_LINKACTION item).
|
|
.LP
|
|
ldap_free_templates() disposes of the templates allocated by
|
|
ldap_init_templates().
|
|
.LP
|
|
ldap_first_disptmpl() returns the first template in the list
|
|
.I tmpllist.
|
|
The
|
|
.I tmpllist
|
|
is typically obtained by calling ldap_init_templates().
|
|
.LP
|
|
ldap_next_disptmpl() returns the template after
|
|
.I tmpl
|
|
in the template list
|
|
.I tmpllist. A
|
|
.SM NULL
|
|
pointer is returned if
|
|
.I tmpl
|
|
is the last template in the list.
|
|
.LP
|
|
ldap_oc2template() searches
|
|
.I tmpllist
|
|
for the best template to use to display an entry that has a specific
|
|
set of objectClass values.
|
|
.I oclist
|
|
should be a null-terminated array of strings that contains the values
|
|
of the objectClass attribute of the entry. A pointer to the first
|
|
template where all of the object classes listed in one of the
|
|
template's dt_oclist elements are contained in
|
|
.I oclist
|
|
is returned. A
|
|
.B NULL
|
|
pointer is returned if no appropriate template is found.
|
|
.LP
|
|
ldap_tmplattrs() returns a null-terminated array that contains the
|
|
names of attributes that need to be retrieved if the template
|
|
.I tmpl
|
|
is to be used to display an entry. The attribute list should be freed
|
|
using ldap_value_free(). The
|
|
.I includeattrs
|
|
parameter contains a null-terminated array of attributes that should
|
|
always be included (it may be
|
|
.B NULL
|
|
if no extra attributes are required). If
|
|
.I syntaxmask
|
|
is non-zero, it is used to restrict the attribute set returned. If
|
|
.I exclude
|
|
is zero, only attributes where the logical AND of the template item
|
|
syntax id and the
|
|
.I syntaxmask
|
|
is non-zero are included. If
|
|
.I exclude
|
|
is non-zero, attributes where the logical AND of the template item
|
|
syntax id and the
|
|
.I syntaxmask
|
|
is non-zero are excluded.
|
|
.LP
|
|
ldap_first_tmplrow() returns a pointer to the first row of items in
|
|
template
|
|
.I tmpl.
|
|
.LP
|
|
ldap_next_tmplrow() returns a pointer to the row that follows
|
|
.I row
|
|
in template
|
|
.I tmpl.
|
|
.LP
|
|
ldap_first_tmplcol() returns a pointer to the first item (in the first
|
|
column) of row
|
|
.I row
|
|
within template
|
|
.I tmpl. A pointer to an ldap_tmplitem structure (defined below
|
|
in the TMPLITEM STRUCTURE ELEMENTS section) is returned.
|
|
.LP
|
|
The
|
|
.B LDAP_SET_TMPLITEM_APPDATA()
|
|
macro is used to set the value of the ti_appdata field in a ldap_tmplitem
|
|
structure. This field is reserved for the calling application to use; it
|
|
is not used internally.
|
|
.LP
|
|
The
|
|
.B LDAP_GET_TMPLITEM_APPDATA()
|
|
macro is used to retrieve the value of the ti_appdata field.
|
|
.LP
|
|
The
|
|
.B LDAP_IS_TMPLITEM_OPTION_SET()
|
|
macro is used to test a ldap_tmplitem structure for the existence of an
|
|
item option. The options currently defined are:
|
|
.B LDAP_DITEM_OPT_READONLY
|
|
(this attribute should not be modified),
|
|
.B LDAP_DITEM_OPT_SORTVALUES
|
|
(it makes sense to sort the values),
|
|
.B LDAP_DITEM_OPT_SINGLEVALUED
|
|
(this attribute can only hold a single value),
|
|
.B LDAP_DITEM_OPT_VALUEREQUIRED
|
|
(this attribute must contain at least one value),
|
|
.B LDAP_DITEM_OPT_HIDEIFEMPTY
|
|
(do not show this item if there are no values), and
|
|
.B LDAP_DITEM_OPT_HIDEIFFALSE
|
|
(for boolean attributes only: hide this item if the value is FALSE).
|
|
.LP
|
|
ldap_next_tmplcol() returns a pointer to the item (column) that follows column
|
|
.I col
|
|
within row
|
|
.I row
|
|
of template
|
|
.I tmpl.
|
|
.SH DISPTMPL STRUCTURE ELEMENTS
|
|
The ldap_disptmpl structure is defined as:
|
|
.nf
|
|
.ft B
|
|
struct ldap_disptmpl {
|
|
char *dt_name;
|
|
char *dt_pluralname;
|
|
char *dt_iconname;
|
|
unsigned long dt_options;
|
|
char *dt_authattrname;
|
|
char *dt_defrdnattrname;
|
|
char *dt_defaddlocation;
|
|
struct ldap_oclist *dt_oclist;
|
|
struct ldap_adddeflist *dt_adddeflist;
|
|
struct ldap_tmplitem *dt_items;
|
|
void *dt_appdata;
|
|
struct ldap_disptmpl *dt_next;
|
|
};
|
|
.ft
|
|
.fi
|
|
The dt_name member is the singular name of the template. The dt_pluralname
|
|
is the plural name. The dt_iconname member will contain the name of an
|
|
icon or other graphical element that can be used to depict entries that
|
|
correspond to this display template. The dt_options contains options which
|
|
may be tested using the LDAP_IS_TMPLITEM_OPTION_SET() macro.
|
|
.LP
|
|
The dt_authattrname contains the name of the DN-syntax attribute whose
|
|
value(s) should be used to authenticate to make changes to an entry. If
|
|
dt_authattrname is NULL, then authenticating as the entry itself is
|
|
appropriate. The dt_defrdnattrname is the name of the attribute that
|
|
is normally used to name entries of this type, e.g., "cn" for person
|
|
entries. The dt_defaddlocation is the distinguished name of an entry
|
|
below which new entries of this type are typically created (its value is
|
|
site-dependent).
|
|
.LP
|
|
dt_oclist is a pointer to a linked list of object class arrays, defined as:
|
|
.nf
|
|
.ft B
|
|
struct ldap_oclist {
|
|
char **oc_objclasses;
|
|
struct ldap_oclist *oc_next;
|
|
};
|
|
.ft
|
|
.fi
|
|
These are used by the ldap_oc2template() routine.
|
|
.LP
|
|
dt_adddeflist is a pointer to a linked list of rules for defaulting the
|
|
values of attributes when new entries are created. The ldap_adddeflist
|
|
structure is defined as:
|
|
.nf
|
|
.ft B
|
|
struct ldap_adddeflist {
|
|
int ad_source;
|
|
char *ad_attrname;
|
|
char *ad_value;
|
|
struct ldap_adddeflist *ad_next;
|
|
};
|
|
.ft
|
|
.fi
|
|
The ad_attrname member contains the name of the attribute whose value this
|
|
rule sets. If ad_source is
|
|
.B LDAP_ADSRC_CONSTANTVALUE
|
|
then the ad_value member contains the (constant) value to use.
|
|
If ad_source is
|
|
.B LDAP_ADSRC_ADDERSDN
|
|
then ad_value is ignored and the distinguished name of the person who
|
|
is adding the new entry is used as the default value for ad_attrname.
|
|
.SH TMPLITEM STRUCTURE ELEMENTS
|
|
The ldap_tmplitem structure is defined as:
|
|
.nf
|
|
.ft B
|
|
struct ldap_tmplitem {
|
|
unsigned long ti_syntaxid;
|
|
unsigned long ti_options;
|
|
char *ti_attrname;
|
|
char *ti_label;
|
|
char **ti_args;
|
|
struct ldap_tmplitem *ti_next_in_row;
|
|
struct ldap_tmplitem *ti_next_in_col;
|
|
void *ti_appdata;
|
|
};
|
|
.ft
|
|
.fi
|
|
.SH SYNTAX IDS
|
|
Syntax ids are found in the ldap_tmplitem structure element ti_syntaxid,
|
|
and they can be used to determine how to display the values for the
|
|
attribute associated with an item. The LDAP_GET_SYN_TYPE() macro can
|
|
be used to return a general type from a syntax id. The five general types
|
|
currently defined are:
|
|
.B LDAP_SYN_TYPE_TEXT
|
|
(for attributes that are most appropriately shown as text),
|
|
.B LDAP_SYN_TYPE_IMAGE
|
|
(for JPEG or FAX format images),
|
|
.B LDAP_SYN_TYPE_BOOLEAN
|
|
(for boolean attributes),
|
|
.B LDAP_SYN_TYPE_BUTTON
|
|
(for attributes whose values are to be retrieved and display only upon
|
|
request, e.g., in response to the press of a button, a JPEG image is
|
|
retrieved, decoded, and displayed), and
|
|
.B LDAP_SYN_TYPE_ACTION
|
|
(for special purpose actions such as "search for the entries where this
|
|
entry is listed in the seeAlso attribute").
|
|
.LP
|
|
The
|
|
.B LDAP_GET_SYN_OPTIONS
|
|
macro can be used to retrieve an unsigned long bitmap that defines
|
|
options. The only currently defined option is
|
|
.B LDAP_SYN_OPT_DEFER,
|
|
which (if set) implies that the values for the attribute should not
|
|
be retrieved until requested.
|
|
.LP
|
|
There are sixteen distinct syntax ids currently defined. These generally
|
|
correspond to one or more X.500 syntaxes.
|
|
.LP
|
|
.B LDAP_SYN_CASEIGNORESTR
|
|
is used for text attributes which are simple strings whose case is ignored
|
|
for comparison purposes.
|
|
.LP
|
|
.B LDAP_SYN_MULTILINESTR
|
|
is used for text attributes which consist of multiple lines,
|
|
e.g., postalAddress, homePostalAddress, multilineDescription, or any
|
|
attributes of syntax caseIgnoreList.
|
|
.LP
|
|
.B LDAP_SYN_RFC822ADDR
|
|
is used for case ignore string attributes that are RFC-822 conformant
|
|
mail addresses, e.g., mail.
|
|
.LP
|
|
.B LDAP_SYN_DN
|
|
is used for attributes with a Distinguished Name syntax, e.g., seeAlso.
|
|
.LP
|
|
.B LDAP_SYN_BOOLEAN
|
|
is used for attributes with a boolean syntax.
|
|
.LP
|
|
.B LDAP_SYN_JPEGIMAGE
|
|
is used for attributes with a jpeg syntax, e.g., jpegPhoto.
|
|
.LP
|
|
.B LDAP_SYN_JPEGBUTTON
|
|
is used to provide a button (or equivalent interface element) that can be
|
|
used to retrieve, decode, and display an attribute of jpeg syntax.
|
|
.LP
|
|
.B LDAP_SYN_FAXIMAGE
|
|
is used for attributes with a photo syntax, e.g., Photo. These are
|
|
actually Group 3 Fax (T.4) format images.
|
|
.LP
|
|
.B LDAP_SYN_FAXBUTTON
|
|
is used to provide a button (or equivalent interface element) that can be
|
|
used to retrieve, decode, and display an attribute of photo syntax.
|
|
.LP
|
|
.B LDAP_SYN_AUDIOBUTTON
|
|
is used to provide a button (or equivalent interface element) that can be
|
|
used to retrieve and play an attribute of audio syntax. Audio values are
|
|
in the "mu law" format, also known as "au" format.
|
|
.LP
|
|
.B LDAP_SYN_TIME
|
|
is used for attributes with the UTCTime syntax, e.g., lastModifiedTime.
|
|
The value(s) should be displayed in complete date and time fashion.
|
|
.LP
|
|
.B LDAP_SYN_DATE
|
|
is used for attributes with the UTCTime syntax, e.g., lastModifiedTime.
|
|
Only the date portion of the value(s) should be displayed.
|
|
.LP
|
|
.B LDAP_SYN_LABELEDURL
|
|
is used for labeledURL attributes.
|
|
.LP
|
|
.B LDAP_SYN_SEARCHACTION
|
|
is used to define a search that is used to retrieve related information.
|
|
If ti_attrname is not NULL, it is assumed to be a boolean attribute which
|
|
will cause no search to be performed if its value is FALSE. The ti_args
|
|
structure member will have four strings in it: ti_args[ 0 ] should be
|
|
the name of an attribute whose values are used to help construct a search
|
|
filter or "-dn" is the distinguished name of the entry being displayed
|
|
should be used, ti_args[ 1 ] should be a filter pattern where any occurrences
|
|
of "%v" are replaced with the value derived from ti_args[ 0 ], ti_args[ 2 ]
|
|
should be the name of an additional attribute to retrieve when performing
|
|
the search, and ti_args[ 3 ] should be a human-consumable name for that
|
|
attribute. The ti_args[ 2 ] attribute is typically displayed along with
|
|
a list of distinguished names when multiple entries are returned by the
|
|
search.
|
|
.LP
|
|
.B LDAP_SYN_LINKACTION
|
|
is used to define a link to another template by name. ti_args[ 0 ] will
|
|
contain the name of the display template to use. The ldap_name2template()
|
|
routine can be used to obtain a pointer to the correct ldap_disptmpl structure.
|
|
.LP
|
|
.B LDAP_SYN_ADDDNACTION
|
|
and
|
|
.B LDAP_SYN_VERIFYDNACTION
|
|
are reserved as actions but currently undefined.
|
|
.SH ERRORS
|
|
The init template functions return
|
|
.B LDAP_TMPL_ERR_VERSION
|
|
if buf points to data that is newer than can be handled,
|
|
.B LDAP_TMPL_ERR_MEM
|
|
if there is a memory allocation problem,
|
|
.B LDAP_TMPL_ERR_SYNTAX
|
|
if there is a problem with the format of the templates buffer or file.
|
|
.B LDAP_TMPL_ERR_FILE
|
|
is returned by
|
|
.B ldap_init_templates
|
|
if the file cannot be read. Other routines generally return
|
|
.B NULL
|
|
upon error.
