If an LDAP client performs an operation directly on a fractional replica and the operation does not match the fractional configuration, the operation is forbidden and the server returns an “unwilling to perform” error.
For example, if a fractional replica is configured with fractional-exclude: *:jpegPhoto and an LDAP client attempts to add a new entry that contains a jpegPhoto attribute, the operation is rejected with an “unwilling to perform” error. This behavior ensures that the domain remains consistent with its fractional configuration definition, which implies that no jpegPhoto attribute can exist on the domain.
