[Solved] Enable telnet as root to 11.31 non-trusted system?

I have a new box that was set up for me and I want to allow telnet to the box as root. I know that it's not secure but due to the nature of what I test I need an easy and reliable way back in if I've messed up the other connection methods(SSH). This is in a protected lab environment. Eventually I'll get sudo setup but I'm not ready for that now.

I can telnet as a regular user and then su to root just fine.
I cannot "telnet remote_server" as root user.
I cannot "telnet localhost" as root user.
I did not have an /etc/securetty file. I tried creating one with "console" in it to see if I could then get in via localhost but it didn't help.
I tried "/usr/lbin/modprpw -k root" and got the message "System is not trusted".
hosts.allow and hosts.deny are both commented out.

Most of the search results I get are about how to disable telnet for root but I have the opposite problem. Where else can I look or what can I do?

k5login

.K5LOGIN(5)                                                     File Formats Manual                                                    .K5LOGIN(5)

NAME

       .k5login - Kerberos V5 acl file for host access.

DESCRIPTION

       The  .k5login  file, which resides in a user's home directory, contains a list of the Kerberos principals.  Anyone with valid tickets for a
       principal in the file is allowed host access with the UID of the user in whose home directory the file resides.  One common use is to place
       a .k5login file in root's home directory, thereby granting system administrators remote root access to the host via Kerberos.

EXAMPLES

       Suppose the user "alice" had a .k5login file in her home directory containing the following line:

                 bob@FUBAR.ORG

       This would allow "bob" to use any of the Kerberos network applications, such as telnet(1), rlogin(1), rsh(1), and rcp(1), to access alice's
       account, using bob's Kerberos tickets.

       Let us further suppose that "alice" is a system administrator.  Alice and the other system administrators would have  their  principals  in
       root's .k5login file on each host:

                 alice@BLEEP.COM
                 joeadmin/root@BLEEP.COM

       This would allow either system administrator to log in to these hosts using their Kerberos tickets instead of having to type the root pass-
       word.  Note that because "bob" retains the Kerberos tickets for his own principal, "bob@FUBAR.ORG", he would not have any of the privileges
       that require alice's tickets, such as root access to any of the site's hosts, or the ability to change alice's password.
