Using the latest WAL (Workflow Activity Library) which can be located from a link on the following Blog Post - The MIMWAL (Custom Workflow Activity Library)
Generate Unique Value: This workflow can be used to create is used to create a Unique Value to be set for almost any attribute within the FIM Portal (FIMService Database) that you wish to be unique to the environment, additionally it is possible to add LDAP Queries perform a look up against an LDAP Directory such as Active Directory and verify that the value being generated is also unique to that source as well. I would recommend using this activity to generate attributes such as:
Technically you would not need to create a workflow for each of the above attributes and in a lot of scenarios 1 of the attribute values would be used for the others as well.
In this example we will use this activity to generate an Account Name for a new user that is created, this type of activity is recommended not only to verify Uniqueness but to verify a specific standard is met as well. For example the company policy may state that the account name is to be generated using the following format.
Option 2 If not Unique and if Middle Name Exist
Option 3 If Not Unique and If No Middle Name Exist
Option 4 If Not Unique and Middle Name Exist
In the FIM / MIM Portal navigate to the Workflow page
Click on New
For Workflow Name type in something that reflects the purpose of the overall workflow that you are creating and keep in mind that some workflows that you build will require multiple activities so the name of the Workflow should represent the workflow as a whole.
I generally Start the name of all my workflows with an underscore so it looks like “_WorkflowNameExample” This pushes all my custom workflows to the top of the list of all my workflows and separates my custom workflows from my default workflows and provides a level of understanding for the next person who has to take over your awesome environment that you are building
For Description it may be helpful to type in a detail of what the Workflow is for, this may help prevent others from creating duplicate workflows.
For Workflow Type select Action for additional information about the other Workflow Actions check out the following Blog Post Understanding Workflows
