kadmin heavy load

[sergio.conrad@laposte.net]

Hi

I have a question about kadmin daemon. I want to simulate a charge of users changing their password on a kerberos server.

I have a bash script with the test procedure.
Everything is working, but when i do more than 20 parallel change, I have got some error:

10 % of the changes got the error:
kadmin: Communication failure with server while initializing kadmin interface

Here is the script:

for num in $(seq 1 20 );
do 
ssh user at kdc "kadmin -p user/admin -k -t /home/user/user.keytab -q 'cpw -pw toto cya3060a'" &
done

Note that the ssh daemon's default have been modified to handle 100 concurrent connection.

Any Idea ?
Thanks
Serge
