Hello..
We are a internet service provider using kerberos 4 in our
authentication server. We have currently 12000 subscribers and more than
450 access ports. We are using a Alpha DEC 7600 as our kerberos server
running OSF/1 v3.2 .
We have DEC terminal servers which will pass the
username to the kerberos server to issue a ticket to the user. The
problem occurs during our peak period where there are many users
logging in to us.
The error message on our terminal server :
"Authentication failed, timed out". The kerberos log during the
peak period show tickets are issue at the rate of 20 per second.
When a 'kinit' was done during that period, the error meassage was "Retry
count exceeded (send_to_kdc)"
Questions:
1) Is the kerberos breaking out when the database reached 10000 ?
2) Is there network congestion ?
3) If not, what are the possible causes ?
4) Is there a way to remedy the situation ?
Thank you very much
Regards
