The attribute syntax description format is described in RFC 4512, section 4.1.5, as shown in this example:
SyntaxDescription = LPAREN WSP numericoid ; object identifier [ SP "DESC" SP qdstring ] ; description extensions WSP RPAREN ; extensions
The attribute syntax description includes these elements:
The numeric OID used to uniquely identify the attribute syntax in the directory server.
An optional description for the syntax. If it is provided, then it must be enclosed in single quotation marks.
An optional set of extensions for the attribute syntax. The directory server does not currently support any extensions for use in attribute syntaxes.
The following example shows the attribute syntax description for the standard directory string syntax:
( 1.3.6.1.4.1.1466.115.121.1.15 DESC 'Directory String' )
In this case, the OID is 1.3.6.1.4.1.1466.115.121.1.15, and the description is Directory String. There are no extensions.
