Accommodating disjoint security realms is a challenge for administrators who have to maintain duplicate data sets and for users who need to recall multiple pass phrases, yet joining security realms together can expose one realm to the weaknesses of the other. In this paper, we compare the Kerberos and NetWare security realms, examine methods of joining the two realms under a single login, and propose an attractive single login design.
