Overview#

Schema checking is the process of ensuring that an LDAP Entry conforms to the constraints defined by the server LDAP Schema. This includes:

• Make sure the entry contains exactly one STRUCTURAL ObjectClass
• If there is a Name Form for the entry's structural class, ensure that the Relative Distinguished Name attributes conform with that name form
• If there is a DIT Content Rule for the entry's structural class, make sure that all of the AUXILIARY are defined
• Make sure that all of the Object Class contained in the entry are defined in the schema
• Make sure that all of the AttributeTypes contained in the entry are defined in the schema and allowed by the object classes and/or DIT content rule
• Make sure that all AttributeTypes required by the entry's object classes and/or DIT Content Rule are present
• Make sure that all SINGLE-VALUE attributes contained in the entry only have one value
• Make sure that the entry's position in the DIT conforms with DIT Structure Rule definitions

Some LDAP Server Implementations allow schema checking to be turned on or off.
