Overview#
GUID is an Attribute defined in EDirectory which is a Universally Unique Identifier for any entry.We believe GUID follows the RFC 4122
Attribute Definition#
The GUID AttributeTypes is defined as:- OID of 2.16.840.1.113719.1.1.4.1.501

EDirectory and DirXML Usages#
There are several different methods that are used to display any given GUID within EDirectory and DirXML,- Display Apache Directory Studio: 4c53c981-5dba-11d9-89a2-890b9bd48a51
- Octet String: 81:C9:53:4C:BA:5D:D9:11:89:A2:89:0B:9B:D4:8A:51
- UUID: 81c9534c-ba5d-d911-89a2-890b9bd48a51
- Edir2Edir Association: {4C53C981-5DBA-11d9-89A2-890B9BD48A51}
- Why would the "11d9" be the ONLY lower case within an association?
- Entitlement Association: {81C9534C-BA5D-D911-89A2-890B9BD48A51}
- We have seen this format referred to as UUID "registry format".
- C1/Imanager Displaying Association: 4C53C9815DBA11D989A2890B9BD48A51
Sure seems like poor coordination and forethought to us.
