  We investigate the vacuum structure of pure SU(N) N=1 super Yang-Mills. The
theory is expected to possess N vacua with associated domain walls. We show
that the newly extended version of the low energy effective Lagrangian for
super Yang-Mills supports the BPS domain wall solutions associated with any two
vacua aligned with the origin of the moduli space. For the two color theory the
domain wall analysis is complete. We also find new non BPS domain wall
solutions connecting any two vacua of the underling SU(N) super Yang-Mills
theory not necessarely aligned. When two vacua are aligned with the origin of
the moduli space these solutions are the BPS ones. We also discuss the generic
BPS domain wall solutions connecting any two vacua within the extended
Veneziano-Yankielowicz theory.
