It seems it's really a bug in RHEL 3, RHEL 2.1 allows a dot, so does RHEL 4.x (and IMHO a dot should be allowed, I don't care if a package from the previous millennium doesn't work anymore) I wonder if I could just install shadow-utils from RHEL4 on my CentOS 3.x boxes (maybe it will work after rebuilding the RPM)
