A new prompt at login time

[Allen, Jack]

        I ran up2date yesterday and have my system completely up to
date. I rebooted this morning and now when I login via telnet, yes that
is just plain old telnet, not ssh, I get the following:

======== 
Red Hat Enterprise Linux AS release 4 (Nahant Update 2) 
Kernel 2.6.9-22.ELsmp on an i686 
login: jca 
Password: 
Your default context is user_u:system_r:unconfined_t. 

Do you want to choose a different one? [n] 
======== 

I just entered a CR and thought this would be a one time things. But it
is not. While the prompt was being displayed I did a who and it does not
show me logged in yet. I did a ps -ef | grep log and see a login process
with the host name and -p option. So it appears the prompt is coming
from the login program or its calls to some PAM routine.

        Does anybody know where this is controlled so I can set a
default and not be prompted each time? 

        Also exactly what is this controlling? 

        If I do id, it shows context=user_u:system_r:unconfined_t 

Thanks:
