What is --with-utmp supposed to buy you anyway? I'm working in a RH 7.2 environment with 2.2.6, using winbindd to authenticate against an NT PDC. Is --with-utmp supposed to cause connected users to show up in a 'who'? It doesn't seem to. Also, is the default of obey pam restrictions = no sufficient to avoid this n^2 problem, or am I better off rebuilding the spec without it? Will that cause me to lose pam_winbind.so et al? I'm looking at a much smaller domain (about 3000 NT id's, with no more than 500-700 concurrent connections). Are there more of these configuration settings that could cause significant bottle-necks?

Thanks,
