Stores the name of an unknown auxiliary class.
When NDS declares an object unknown that contains attributes from what appears to be an auxiliary class, NDS adds this attribute to the object and stores the names of the auxiliary classes in this attribute.
For help in understanding the attribute definition template, see Reading NDS Attribute Type Definitions.
For LDAP clients to access this attribute, the LDAP server must be configured to map the attribute to a name without spaces or colons.
