Cyberoam CTAC (Thin Client agent) compatibility with Sophos UTM v9.4

I´ve posted this in another thread but since it's marked as solved, I´ve decided to open a new question.

I could note that for the 9.4 version it´s not planned to include initially the STAC (Sophos Thinclient agent). But the recent Sophos STAS created is very similar to the Cyberoam existing CTAS, maybe a ported version.

So my question is: Would be the Cyberoam CTAC (Thin Client agent) be compatible with Sophos UTM v9.4?

If not, there is no way currently to authenticate Windows Terminal Server users in Sophos UTM configured in transparent mode?

Best Regards,
