The login program uses a dynamically linked crypt authentication, whereas the xdm program is (typically) statically linked. So your xdm is using the MD5 or crypt authentication (whichever it was linked with) and your login is using the crypt or MD5 authentication (whichever library was installed last). What this generally means is that you set your passwords, then you installed the security distribution. If you update the login code to the code from -current, it will recognize *either* MD5 or crypt, and then act accordingly. You *could* boot into single user mode, remount the root read/write, and then use "vipw" to remove the root password entirely. Then use passwd to set the root password. After you do this, you will be able to login on the console, but not on xdm (until you replace your xdm). This is described in the handbook on www.freebsd.org. Moral: don't set any passwords until you've installed libcrypt, if you are going to install it.
