SOGo - How to force external login with email account?

Hi Nas,

There are two places where I found configuration files for SOGo.
I have tried to make a custom template for 05general_preferences, inserting this line:

$S{SOGoForceExternalLoginWithEmail} = 'YES';

after this line:

$S{SOGoMailingMechanism} = 'smtp';

without success.

More than likely I'm wrong. Where?

EDIT

I made a custom template in Zentyal with this and it's working.
