I have been assigned the dubious task of creating a centralized security process for all of my agency’s applications (20+). The environment is heterogenous (UNIX, Bull Mainframe, W2k servers, Novell servers, Unisys mainframe) with varying front andback ends. I plan to begin by creating a central database that will include all elements needed by each application to authenticate and authorize a user but I’m not sure how to proceed from there. What I’m seeking is suggestions on how to best approach this opportunity. In other words, has this wheel already been invented? Thanks, in advance, for any assistance.
