3540.0. "KERBEROS SECURITY PROBLEM" by TKTV20::TAKAHASI () Tue May 27 1997 10:50

Hello,

A customer(InterNet Provider) ask me a question about kerberos security 
for DECServer90M.

Customer has two DECServer90M's.

Until last week, those machines work using kerberos security.
After changing one DECserver90M because hard trouble, customer set up 
kerberos security,again. But can not set up it with following message.
What shall I set up kerberos security for both DECserver90M? 
Please teach me how to set up kerberos security at DECServer90.

Error message:

local> CHANGE KERBEROS DEFAULT REALM FOCUS.OR.JP
Local -463- Only one default security server realm allowed

What you need to do in this case is:

	CHANGE KERBEROS NODEFAULT REALM REALMNAME 
	CHANGE KERBEROS DEFAULT REALM FOCUS.OR.JP

The default property on realms must be explicitly removed.  This is to prevent
mistakes.  To change default realms un-do the old one, then do the new one.

Is this a valid realm?  The name REALMNAME looks odd, like some example text.

>Realm:                    FOCUS.OR.JP          
>  Secret:                 (None)

>    Dialback Number:      (None)

>    Permissions:          NODIALBACK, NODIALOUT, LAT, TELNET, SLIP, PPP, PRIV

This realm (the one I suspect you want) has no host nor is it default.  I'd
guess someone typed the following two commands:

  CHANGE KERBEROS REALM FOCUS.OR.JP
  CHANGE KERBEROS DEFAULT REALM REALMNAME MASTER HOST mailgate.focus.or.jp 

Where REALMNAME in the second command should have been FOCUS.OR.JP.
