DIA-25718
Invalid value of CLIENT_ID in the client configuration
Cause
An attempt is being made to authenticate a user from an external identity provider to the Oracle Database using a CLIENT_ID value that is not correctly formatted as provided by Azure AD. This parameter can be set in SQLNET.ORA, TNSNAMES.ORA, connect string, or set by assigning the OCI_ATTR_OAUTH2_CLIENTID attribute in a user session (OCISession) or authentication (OCIAuthInfo) handle.
Make sure you copy the 36-character string of hexadecimal characters and hyphens exactly as provided by Azure AD.
Action
Specify the correct CLIENT_ID value. Refer to the Oracle Database documentation for the allowed values.
