HP-UX AAA Server A.08.02 Administrator's Guide

• “No Instance Specification.”
• “Numeric Instance Specification.”
• “Keyword Instance Specification” (page 309)
The following sections describe these keywords in detail.
Attribute Names
Attribute names defined in the server's dictionary file can be used. Attribute names are
case-insensitive. For example, Reply-Message is considered identical with REPLY-MESSAGE.
For more information on attribute names, see “The dictionary File ” (page 390).
Vendor Names
If multiple vendors have used the same name to define an attribute, you must differentiate these
names by prefixing the vendor’s name to that of the attribute in the following format.
<vendor-name>:<attribute-name>
Vendor names are defined in the server's vendors file. For more information on vendor names
and the syntax of vendor names in the vendors file, see “The vendors File ” (page 395).
Attribute Instance Specifications
A given attribute can have more than one instance on the request. As a result, you must specify
the instance of a given attribute that is of interest. You must also specify the absolute location of
an attribute instance (for example, when inserting an attribute name).
Attribute instance specifications are provided using the [] syntax, after the attribute name. The
instance of interest is indicated inside the square brackets ([]). You can specify an attribute instance
in one of the following ways:
• “No Instance Specification.”
• “Numeric Instance Specification.”
• “Keyword Instance Specification” (page 309)
While specifying attribute instance specifications, ensure that there is no white space around and
between the square brackets ([]).
No Instance Specification
You need not specify a specific instance if it is of no consequence. The no instance specification
is equivalent to specifying the last keyword. For more information on the last keyword, see
“Keyword Instance Specification.”
Numeric Instance Specification
When a specific instance is required, you can specify it numerically. Instances are numbered from
0 (the first instance). Negative instance numbers are not allowed.
Keyword Instance Specification
When a specific instance is required, it can be specified using one of the following keywords, or
by using the asterisk (*) symbol:
• The begin keyword: If you want to specify an attribute instance located at the beginning of
the list, use the begin keyword. This keyword is supported only by the insert command,
on the left side of the = operator. Following is an example of a correctly formatted keyword
instance specification:
insert Reply-Message[begin] = "This is first"
For more information on the insert command, see “The insert Command” (page 303).
