can anyone offer some suggestions about off the shelf applications for managing passwords on an nt / 2000 server (want to use something other than the MS user groups)? we need to add password protection to some of our web sites. we would like people to be able to set thier own passwords, and the aplication should provide a cookie that both remembers the user for future visits and will time-out the user if they have been idle for too long. any suggestions are appreciated.
