The first custom workflow activity I wrote was one to select a unique value<\/a> from a list of possible values placed in WorkflowData variables. I’ve now re-written this as a PowerShell script to use with the open source FIM PowerShell activity<\/a>.<\/p>\n

The script here just checks again the Portal, but it would be a simple modification to make it check against AD instead\/as well.<\/p>\n

<\/p>\n

Setting up the Workflow<\/strong><\/p>\n

First you have to get the FIM PowerShell activity installed. See here<\/a> for the extra steps I did to get it working with the FIM PowerShell cmdlets.<\/p>\n

The script expects to find one or more options in WorkflowData parameters.\u00c2\u00a0Here is what the Workflow definition looks like:<\/p>\n

\"\"<\/a>\u00c2\u00a0<\/p>\n

The options are just Function Evaluators:<\/p>\n

\"\"<\/a><\/p>\n

Then the FIM PowerShell activity calls my script:<\/p>\n
