Auth string for AD changed from ComponentAuthenticator to DialogUserAccountBased in all processes for no reason

For no apparent reason AuthenticationString  variable value in all AD process step is changed 

atribute with value Value = ConnectionInfo.AuthString had Yesterday calculated value in the runnining process value:


today is 

DialogUserAccountBased ...and is saying that this module is not activated

...which is true as it does not need to be. Ant thus getting error.

Any idea how to get back to ComponentAuthenticator?
