LDAP-UX Client Services B.04.15 Administrator's Guide

try using the first specified equivalent or substitution syntax supported by the target LDAP
directory server. The specified equivalent syntax of 2.5.5.5 syntax with the oMSyntax value
of 22 is supported on windows ADS and will be used in place of the original syntax value.
As another example, assume an attribute type with a Boolean equality rule is being installed on
the LDAP server where this matching rule is not supported. Since no substitution policy is
specified for this matching rule in the example above, the default substitution matching rule,
caseIgnoreMatch, would be used instead, if the LDAP server supports it. If the LDAP server
does not support caseIgnoreMatch, that attribute type cannot be installed on the LDAP server,
unless its definition is modified to use another supported equality matching rule.
If the –s– option is specified in the ldapsechema tool, syntax substitution in attribute types is
disabled. Any attribute types with unsupported LDAP syntaxes will not be added to the LDAP
directory server schema. The –m– option with the ldapschema tool disables matching rule
substitution. Any attribute types with unsupported matching rules will not be added to the
LDAP directory server schema.
