cut -d ":" -f3,5 /etc/passwd | tr ":" " "
or by using sed
sed "s/\(.*\):\(.*\):\(.*\):\(.*\):\(.*\):\(.*\)/\3 \5" /etc/passwd

MUPDATETEST(1) General Commands Manual MUPDATETEST(1)

NAME
mupdatetest - interactive MUPDATE test program
SYNOPSIS
mupdatetest [ -p port ] [ -m mechanism ]
[ -a userid ] [ -u userid ] [ -k num ] [ -l num ]
[ -r realm ] [ -f file ] [ -n num ] [ -q ]
[ -c ] [ -i ] [ -o option=value ] [ -v ] hostname
DESCRIPTION
mupdatetest is a utility that allows you to authenticate to a MUPDATE server and interactively issue commands to it. Once authenticated you
may issue any MUPDATE command by simply typing it in. It is capable of multiple SASL authentication mechanisms and handles encryption lay-
ers transparently. This utility is often used for testing the operation of a mupdate server. Note that you must be an admin in order to
authenticate to an mupdate server.
OPTIONS
-p port
Port to connect to. If left off this defaults to mupdate as defined in /etc/services.
-m mechanism
Force mupdatetest to use mechanism for authentication. If not specified the strongest authentication mechanism supported by the
server is chosen.
-a userid
Userid to use for authentication; defaults to the current user. This is the userid whose password or credentials will be presented
to the server for verification.
-u userid
Userid to use for authorization; defaults to the current user. This is the userid whose identity will be assumed after authentica-
tion. NOTE: This is only used with SASL mechanisms that allow proxying (e.g. PLAIN, DIGEST-MD5).
-k num Minimum protection layer required.
-l num Maximum protection layer to use (0=none; 1=integrity; etc). For example if you are using the KERBEROS_V4 authentication mechanism
specifying 0 will force mupdatetest to not use any layer and specifying 1 will force it to use the integrity layer. By default the
maximum supported protection layer will be used.
-r realm
Specify the realm to use. Certain authentication mechanisms (e.g. DIGEST-MD5) may require one to specify the realm.
-f file
Pipe file into connection after authentication.
-n num Number of authentication attempts; default = 1. The client will attempt to fast reauth (e.g. DIGEST-MD5), if possible.
-q Enable MUPDATE COMPRESSion (before the last authentication attempt).
-c Enable challenge prompt callbacks. This will cause the OTP mechanism to ask for the the one-time password instead of the secret
pass-phrase (library generates the correct response).
-i Don't send an initial client response for SASL mechanisms, even if the protocol supports it.
-o option=value
Set the SASL option to value.
-v Verbose. Print out more information than usual.
