what's happening is in the pre-installation script, it checks to see if the 
user exists using id(1), which is probably the right thing.  if the user 
exists, but its primary group is not set to nagios, then it attempts to fix 
this by calling usermod.  however, usermod only supports users 
in /etc/password, which is what the cause of the problem is.

i think this code pre-dates my maintenance of the package...  so you recommend 
that we replace it with "adduser --system --group nagios", and remove the 
usermod stuff and extra logic?

well if we had the user named Debian-nagios, and they had that in LDAP, i 
think it would be the same problem, no?
