4. On the Specify Array Credentials page, enter credentials that this array manager should use when connecting to array members.

   You must provide credentials with an array administrator role in Forefront Threat Management Gateway (TMG) running on the Forefront UAG server. By default, the user that installs Forefront UAG has an array administrator role. If you want to use a different account, note the following:

   • It must be a domain account that is recognized by all array members.
     
     
   • The account should have local administrator permissions on the array manager server, and on all array members.
     
     
   • It is recommended to use an account with a long expiry period.
     
     
   • Ensure that you are logged on to the server, with the credentials that you will specify when running the Array Management Wizard.
