ODP.NET Integrated Security Invalid Connection String Argument

Question

What am I missing?

<add name="test" 
    connectionString="Data Source=TEST_ORACLE;Integrated Security=Yes;" />

[ArgumentException: 'Integrated Security' is an invalid connection string attribute]
   Oracle.DataAccess.Client.OracleConnection.ParseConnectionString() +2707
   Oracle.DataAccess.Client.OracleConnection.set_ConnectionString(String value) +533
   Oracle.DataAccess.Client.OracleConnection..ctor(String connectionString) +210

ODP.NET: Oracle.DataAccess - 2.102.2.20 (I am using a bindingRedirect to this version.)

If I take out Integrated Security and declare User ID and password then it functions correctly. So, I know there is nothing wrong with ODP.NET.
