Bug Description

Setting up snmpd (5.4.2.1~dfsg0ubuntu1-0ubuntu2.1) ...
userdel: cannot remove entry 'snmp' from /etc/passwd
/usr/sbin/deluser: `/usr/sbin/userdel snmp' returned error code 1. Exiting.
dpkg: error processing snmpd (--configure):
 subprocess installed post-installation script returned error exit status 1

We use ldap authentication, so deluser fails (correctly, as I don't want packages wandering around screwing up global user/group entries.)

Removing the deluser/adduser block from the postinst (leaving the chown there) works fine.

I noticed that the proposed branch ( lp:~shuff/ubuntu/precise/net-snmp/fix-for-701944 ) includes a new copy of the line:
  if [ ! `getent passwd snmp >/dev/null` ]; then
(and also leaves the existing "group" line untouched), so I thought it was worth mentioning debbugs #609430, which points out that the combo of backticks and redirection to /dev/null means the expression doesn't work as intended...
