Comment 12 for bug 270328

53-1ubuntu8 is the correct version of ecryptfs-utils with pam-auth-update integration for intrepid. So the only issue here is that somewhere along the line, the kerberos_example profile from auth-client-config was enabled. If this can be traced back to a package enabling it for you without your knowledge, then that should be treated as a bug on that package. You may want to check for references to auth-client-config in the /var/lib/dpkg/info directory on your system?

The issue with dpkg-reconfigure giving errors will be fixed with the next pam upload, which is still pending.
