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
• NAME: GUID
• DESC: GUID is an Attribute defined in EDirectory which is a Universally Unique Identifier for any entry.
• EQUALITY:
• ORDERING:
• SYNTAX: 1.3.6.1.4.1.1466.115.121.1.40 Octet String
• UPPERBOUND: 16
• SINGLE-VALUE
• NO-USER-MODIFICATION
• USAGE DirectoryOperation
• X-NDS_LOWER_BOUND: 16
• X-NDS_UPPER_BOUND: 16
• X-NDS_PUBLIC_READ: 1
• X-NDS_NONREMOVABLE: 1
• X-NDS_FILTERED_REQUIRED: 1
• X-NDS_READ_FILTERED: 1

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.
