Hi Ian,
Yes it is...
e.g.
Après qu'il s'est rasé , nous sommes sortis.
Après qu'il se sera rasé, nous sortirons.
Après que should be followed by an Indicative tense, although you will hear French people using a subjunctive in everyday language probably because 'Avant que' is followed by the subjunctive.
But the Académie Française is quite adamant that this is a mistake (often made by authors) but tolerated 'en langage courant'..
Hope this helps!
