  The boundary OSP(1|2) WZNW model possesses two types of branes, which are
localized on supersymmetric Euclidean AdS$_2$ and on two-dimensional
superspheres. We compute the coupling of closed strings to these branes with
two different methods. The first one uses factorization constraints and the
other one a correspondence to boundary N=1 super-Liouville field theory, which
we proof with path integral techniques. We check that the results obey the
Cardy condition and reproduce the semi-classical computations. For the check we
also compute the spectral density of open strings that are attached to the
non-compact branes.
