After compiling my kernel, common user access denied.
 

I have customized my FreeBSD 5.3 kernel successfully.
However, after the compiling, I can only login as root. common user access denied.
What was worse, when I login as root, I can enter the system directly. No password needed to login, so strange! I think it is insecure for my system.
What is wrong?

Give me a hand, please! Thanks.

Is your boot failing and dropping you into single user mode?

What messages are you getting right before it lets you get a prompt.

try to recompile without removing to much stuff. Did you also do a buildworld without using mergemaster?

I just do like this:
cd /usr/src.sys/i386/conf
cp GENERIC MYKERNEL

cd /usr/src
make buildkernel KERNCONF=MYKERNEL

After this, it booted quite well, when the daemon appeared, I choose to select the default, not the single-user mode.
In addition, I am using multi-OS. I use Boot-manager to load the systems, but I don't think this should be the cause.

Sorry, I also typed such a command after the compiling:
make installkernel KERNCONF=MYKERNEL

I know you are trying to boot into multi-user mode but it sounds like the boot is failing -- which means it will dump you into single user mode to fix the boot.

What messages are you getting right before it asks you what shell you want?

I reinstalled my FreeBSD and I found exactly where and when I failed to login as common user.
It happened exactly after I installed the source code. ((((not after my compiling)))). I use sysinstall to install the source code.

Anything wrong? I have no idea.
