Today’s tip…
PowerShell Web Access (PWA) works off a "whitelist" security model whereby permissions must be granted for users to access machines.
PS C:\> Get-PswaAuthorizationRule
Id RuleName User Destination
-- -------- ---- -----------
0 Rule 0 contoso\user1 SERVER1.contoso.com
The following command may be used for testing or troubleshooting purposes to allow all users to access all machines.
PS C:\> Add-PswaAuthorizationRule * * *
This can be very useful if you need a litmus test to determine if a whitelist configuration problem is responsible for "an authorization failure occurred" or other errors.
