Track Admin accounts

Hi Dave,

you can use this EA:

dscl . -read /Groups/admin | grep GroupMembership | awk -F "[':']" '{print $2}' | sed 's/^.//' | tr " " " " | wc -l

This EA count the Admin users on each Machine and you can create a Smartgroup to display this list.

You don't need to grep for GroupMembership, you can call items directly with dscl and again I would use cut, less overhead than awk and now you don't need to remove leading whitespace:

dscl . -read /Groups/admin GroupMembership | cut -d " " -f 2- | tr " " " "

The variable 'NF' in awk is a built-in variable that represents the number of fields in the record. Since the first field is always "GroupMembership:", you subtract one to get the number of users.

This will get you the count of admin users

#!/bin/bash
adminAccts=$(dscl . -read /Groups/admin | awk '/GroupMembership/ { print NF-1; }')
echo "<result>${adminAccts}</result>"

This will get you the list of admin users

#!/bin/bash
adminUsers=$(dscl . -read /Groups/admin | awk '/GroupMembership/ { for (n=2;n<=NF;n++) { print $n; } }')
echo "<result>${adminUsers}</result>"

If ran as a log in script via Casper $3 returns current user

dscl . read /Groups/admin GroupMembership | grep -c $3

if it equals 1 it is a member, if it equals 0 not a member

Tom, thanks for this. I am unsure how to utilize this script in the workflow. I have the following (maybe I am missing something).

#!/bin/bash

dscl . read /Groups/admin GroupMembership | grep -c $3

exit 0

That is, once set up as a policy -> login script how do I further configure the policy to utilize "equals 1" to list the admin users in either an inventory report or smart group?

Thanks

something like this:

#!/bin/bash

if [[ `dscl . read /Groups/admin GroupMembership | grep -c $3` == 1 ]]

   then echo "$3 is an admin"
   else echo "$3 is not an admin"

fi

exit 0
