These are Schema related [LDAP SearchFilters] which show [LDAP Query Examples] that can be used to find information specific to the Schema LDAP.

The RFC recommend that the [RootDSE Example] publish an entry for "[SubschemaSubentry]".

The [SubschemaSubentry] is the [DN] of the location of the schema. 

A typical entry is:
{{{
subschemaSubentry: cn=schema
}}}

Once this value is obtained the ldapsearch command may be used to obtain the schema for the LDAP server:
{{{
ldapsearch -h yourLDAPDNS  -b "cn=schema" -s base -D cn=admin,ou=...,dc=yourdomain,dc=com -w secretpassword "(objectclass=*)" >2008-11-09-schema.ldif
}}}

Some [LDAP Server Implementations] prefer this type of syntax.
{{{
ldapsearch -h yourLDAPDNS  -b "cn=schema" -s base -D cn=admin,ou=...,dc=yourdomain,dc=com -w secretpassword "(objectclass=*)" attributeTypes dITStructureRules objectClasses nameForms dITContentRules matchingRules ldapSyntaxes matchingRuleUse
}}}

This will store the schema in an LDIF file named 2008-11-09-schema.ldif.
