Problem with kerberos 5 binaries

[Rahul Raman]

Hi,

I have been having the following problems on multiple platforms where I 
downloaded the kerberos binaries from the  MIT Kerberos distribution Page

For example on a SGI Octane with  IRIX 6.5 I downloaded the 
mips-sgi-irix6.5.tar (Kerberos 5-1.2.5) file. I did tar -xvf and that 
installed the necessary images under /usr/local/bin and /usr/local/sbin 
directories. I followed the instructions from the 
http://web.mit.edu/is/unix-vms/kerbinstall.html page and downloaded the 
files /etc/krb.conf, /etc/krb5.conf and /etc/krb.realms. I also edited the 
inetd.conf and /etc/services file to support only kerberized incoming 
connections. I got the srvtab file by sending a mail to accounts at mit.edu 
and I ftp'd the file to my local machine (/etc/srvtab). I used ktutil to 
generate krb5.keytab from the /etc/srvtab file on my local machine

For some reason, the incoming telnet and ftp connections do not recognize 
Kerberos 5 tickets and it gives the following messages
[Kerberos 5 refuses authentication because telnetd: krb5_rd_req failed: 
Unknown key table type]
[Kerberos 5 refuses authentication because telnetd: krb5_rd_req failed: 
Unknown key table type]
[Kerberos 5 refuses authentication because telnetd: krb5_rd_req failed: 
Unknown key table type]
[Trying KERBEROS4 . . .]
[ Kerberos V4 accepts you ]
[ Kerberos V4 challenge successful ]

Although I do get kerberized access I am a bit concerned that Kerberos 5 
authentication is not accepted by the server.

Please help with this problem or point me to the right resource if this 
problem had been raised by other users and there is a solution to it somewhere.

Thanks a lot
