A Global Unique Identifier (GUID) is a unique identifier assigned to every entry in the Oracle Internet Directory (OID). The Oracle Internet Directory is the primary repository for storing information about Oracle Portal users and groups. Any user or group entry can be identified within the Oracle Internet Directory by its GUID, which is stored as one of its attributes. When a user or group is deleted and recreated with identical attributes, it still has a different GUID. Oracle Portal maintains a cache of some users and groups in its local repository for better performance. It uses GUID to cross-reference the cached entries with those stored in the Oracle Internet Directory. wwsec_api functions id, id_sso, group_id and group_info all make use of the Global Unique Identifier (GUID).
