If a user send an inappropriate email to a loads of people or get stung by some sort of email exploit you can quickly delete the email from all of the recipients using a GAM command.
Step 1 - get the email header
Go into Google Vault and search for the offending user or someone known to have got the message.
Click show details and grab the email ID. This will be a long string of characters followed by @mail.gmail.com
Step 2 - find out who has the email
Go into Google Vault and find the original message sent by the offending user. Look at the details to see who got it. Copy the list and dump it into a spreadsheet. Clean up to just a list of emails with a column header 'mail'. Save as a csv file.
Step 3 - delete messages with GAM
Put your CSV file in your GAM folder - this e.g. assumes its called mail.csv

With the release of Chrome and ChomeOS 37 an update to the management console has arrived that allows you to push bookmarks to users.
Under Device Management > Chrome > User Settings > User Experience you will now find the option to add managed bookmarks.
In the example above, the bookmarks are applied to the sub-OU of 'students' - so all our students will get these bookmarks. Simply add your url and the bookmark name, click the + and save. These will appear in a folder called 'yourdomain bookmarks' - see below:
Be aware that to get these bookmarks applied on a Windows/OS-X device the user must be signed into Chrome. Update: if you install the latest group policy template you can push the bookmarks via policy on PCs - details are given here.
I've been a long time user of ClearOS for gateway, DNS,DHCP, backup and a variety of other services. It is a Linux distro that is backed up with a marketplace of great apps that can be easily managed via a web config (although you can drop into cli whenever you want more control). The new samba directory app allows ClearOS to behave as a full on Windows Domain controller and file server without the cost of Windows Server.
So this is a demo from installation to a working DC and files server. Its about 40 mins for the full job - so skip though bits - gives you an example of what you can do. Please note the the Samba Directory App is currently in beta - but I've not spotted any bugs in a my test setup yet.
