blocking logins at server

[twk]

We are running both 1.5.x and 2.1.x versions of Cyrus. I have a $#%$^#$%^ user that has his email client set to check every folder ever few seconds. I can't remove him from the password file, as we use Kerberos for authentication. I don't want to disable him in kerberos, just block his logins to the server. Is there any relatively straightforward way to do this?

Thanks,
Tom
