Integrated Security problem in Connection string

I have the following problem regarding oracle client connection string from .net web service, any help please?

Error Message: 'integrated security' is an invalid connection string attribute
Stack Trace:    at Oracle.ManagedDataAccess.Client.ConnectionString.SetProperty(String key, String value, String quotedValue)
   at Oracle.ManagedDataAccess.Client.ConnectionString.Parse(String constr)
   at Oracle.ManagedDataAccess.Client.ConnectionString..ctor(String constring)

   at Oracle.ManagedDataAccess.Client.OracleConnection.set_ConnectionString(String value)
   at Oracle.ManagedDataAccess.Client.OracleConnection..ctor(String connectionString)
   at MyCode.DataAccess.Repository.insert(Company oCompany)

the connection string is 

<add connectionString="Persist Security Info=False;Integrated Security=False;Password=123;User ID=USER1;Data Source=testDB" name="ConnectionString" providerName="Oracle.DataAccess.Client" />
