Abstract
I review how orbifold and simple-current techniques can be used to obtain boundary states for non-diagonal modular invariants as well as boundary states preserving only part of the bulk symmetries. I will illustrate this construction using as examples the SU(2) k WZW models, the conformai theories at c = 1 and the superconformai theories at c = 3/2, including the isolated Ginsparg points.
