<h4 id="rzahyibmattras">The IBMAttributeTypes attribute</h4>
|
|
<p>The IBMAttributeTypes attribute can be used to define schema information
|
|
not covered by the LDAP Version 3 standard for attributes. Values of IBMAttributeTypes
|
|
must comply with the following grammar:</p>
|
|
<pre class="xmp">IBMAttributeTypesDescription = "(" whsp
|
|
numericoid whsp
|
|
[ "DBNAME" qdescrs ] ; at most 2 names (table, column)
|
|
[ "ACCESS-CLASS" whsp IBMAccessClass whsp ]
|
|
[ "LENGTH" wlen whsp ] ; maximum length of attribute
|
|
[ "EQUALITY" [ IBMwlen ] whsp ] ; create index for matching rule
|
|
[ "ORDERING" [ IBMwlen ] whsp ] ; create index for matching rule
|
|
[ "APPROX" [ IBMwlen ] whsp ] ; create index for matching rule
|
|
[ "SUBSTR" [ IBMwlen ] whsp ] ; create index for matching rule
|
|
[ "REVERSE" [ IBMwlen ] whsp ] ; reverse index for substring
|
|
whsp ")"
|
|
|
|
IBMAccessClass =
|
|
"NORMAL" / ; this is the default
|
|
"SENSITIVE" /
|
|
"CRITICAL" /
|
|
"RESTRICTED" /
|
|
"SYSTEM" /
|
|
"OBJECT"
|
|
|
|
IBMwlen = whsp len
|
|
</pre>
|
|
<dl>
|
|
<dt class="bold">Numericoid </dt>
|
|
<dd>Used to correlate the value in attributetypes with the value
|
|
in IBMAttributeTypes.
|
|
</dd>
|
|
<dt class="bold">DBNAME </dt>
|
|
<dd>You can provide 2 names at the most, if indeed 2 names are given. The
|
|
first is the table name used for this attribute. The second is the column
|
|
name used for the fully normalized value of the attribute in the table. If
|
|
you provide only one name, it is used as the table name as well as the column
|
|
name. If you do not provide any DBNAMEs, then a name based on the first seventeen
|
|
characters of the attribute name (which must be unique) is used. Database
|
|
table and column names are limited to seventeen characters.
|
|
</dd>
|
|
<dt class="bold">ACCESS-CLASS </dt>
|
|
<dd>The access classification for this attribute type. If ACCESS-CLASS
|
|
is omitted, it defaults to normal.
|
|
</dd>
|
|
<dt class="bold">LENGTH </dt>
|
|
<dd>The maximum length of this attribute. The length is expressed
|
|
as the number of bytes. Directory Server has a provision for specifying the
|
|
length of an attribute. In the attributetypes value, the string:
|
|
|
|
<pre class="xmp">( attr-oid ... SYNTAX syntax-oid{len} ... )</pre>can be used
|
|
to indicate that the attributetype with oid attr-oid has a maximum length.
|
|
</dd>
|
|
<dt class="bold">EQUALITY, ORDERING, APPROX, SUBSTR, REVERSE </dt>
|
|
<dd>If any of these attributes are used, an index is created for
|
|
the corresponding matching rule. The optional length specifies the width of
|
|
the indexed column. A single index is used to implement multiple matching
|
|
rules. The Directory Server assigns a length of 500 when one is not provided
|
|
by the user. The server can also use a shorter length than what the user requested
|
|
when it makes sense to do so. For example, when the length of the index exceeds
|
|
the maximum length of the attribute, the index length is ignored.
