23.7 Alphabetized Database-Map Types | 909
Proceedings, Winter 1991). The hash type is available only if sendmail was compiled with
NEWDB defined and the Berkeley or Sleepycat db(3) library linked.
The hash type is the default that is used with most of the features offered by the mc configuration
technique (see Table 23-4 on page 896). For example, consider the following:
Kuudomain hash -o /etc/mail/uudomain
Here, a database map named uudomain is declared to be of type hash. Th e-o says that the
database file /etc/mail/uudomain is optional.
Quite a few other database-map switches are available with this type. The complete list is
shown in Table 23-13.
The -d38.20 command-line switch(?§15.7.53 on page 568) can be used to observe this
type??™s lookups in more detail. See also the btree type (?§23.7.2 on page 901).
23.7.8 hesiod
MIT network user authentication services V8.7 and later
The hesiod type of database map uses the Hesiod system, a network information system
developed as Project Athena. Support of hesiod database maps is available only if you
declare HESIOD when compiling sendmail. (See ?§3.4.13 on page 115 for a fuller description
of the Hesiod system.)
A hesiod database map is declared like this:
Kname hesiod HesiodNameType
The HesiodNameType must be one that is known at your site, such as passwd or service.
