Description: Privacy password. Setting the field to a non zero-length value will convert the given password to a localized privacy key, appropriate to the corresponding usmUserAuthProtocol field. The key is localized using the appropriate usmUserEngineID field, according to the algorithm specified in RFC 2574. This field may be set to a non zero-length value if the following conditions hold: 1) This is the creation of the entry. 2) The value of the corresponding usmUserCloneFrom field is zeroDotZero. Setting the field in any other case will cause no effect.
