The Pattern attribute contains a substitution schema. The values refer to the four substrings created from the username by the Match attribute. The term ${1} pertains to the userid, which is located in the first substring of the username. Since a UPN includes domain information, the Pattern attribute does not require complete values for the terms ${2}, ${3}, and ${4}.
An identity map substitutes corresponding substrings from the logon username, for example:
| For the username... | ${1} | ${2} | ${3} | ${4} | Result |
