This article details how to set up a user account with either domain or global administrator access to allow them to do administrative tasks in SecurityGateway.ay
From the Dashboard, after logging in with a Global Administator account:
Click on Setup / Users in the bottom-left corner
Locate the Accounts section.
Click on Domains and Users

Click on the domain containing the user you wish to make an administrator under the Domains section

Click Users

Select the user and click on the Edit button.

Check the box next to 'Account is an administrator', and then choose between Global or Domain Administrator

If giving Domain Administrator permission, select the domains they will administer
Click the right arrow to move those domains to the Selected Domains window
Additional Comments
If the account is set as a Global Administrator, the Available and Selected Domains section will be greyed out, as Global Administrators can edit any domain in SecurityGateway's settings.
The original address created during installation of the SecurityGateway server is automatically a global administrator.
Note that disabling administrative access is the same as above, except you uncheck the box next to 'Account is an administrator'.
