Script-based authorization
Script-based authorization
If you'd like to make authorization decisions outside of a static ACL model, you can utilize a PowerShell script to do this.
Access Manager can call a script that contains a function called Get-AuthorizationResponse
that takes a user, computer, and logger as input parameters. From there you can make a decision on what the user should be allowed or denied access to, or choose to not make an authorization decision at all.
Access Manager uses the response you provide to create a dynamic ACL for the user, and includes it in the access evaluation of all applicable targets.
Example script
Logging information
You can use the Write-Information, Write-Warning, Write-Verbose cmdlets to write to the AMS log file and document your authorization decisions. Note that if you use Write-Error, or if an exception is thrown and not handled, the authorization evaluation for the entire access request will fail.
Performance
Be aware of performance when writing external authorization scripts. From the user's perspective, they will be waiting in the browser while the access evaluation takes place. If you have a slow script, or lots of scripts, this wait time may seem excessive.
Scripts that take longer than 30 seconds to complete will be terminated by Access Manager, and the user's authorization request will fail.
