Task.Definition.Principal.Account is null if in the UserId property of the task XML, is set in plain text, instead of SID

I need to get a task’ associated principal, which is set in ‘When running the task use the following user account’. However, on some machines, the UserId in the task’s XML is represented by Sid:

<Principal id="Author">
      <RunLevel>HighestAvailable</RunLevel>
      <UserId>S-1-5-21-2025382838-34760544-43243242434-1106</UserId>
      <LogonType>Password</LogonType>
</Principal>

In which case this works fine and I can retrieve the account, but on other machines the UserId is represented in plain text:

<Principal id="Author">
      <RunLevel>HighestAvailable</RunLevel>
      <UserId>Domain\User</UserId>
      <LogonType>Password</LogonType>
</Principal>

In which case Task.Definition.Principal.Account returns null

@karthimahendran Use the Account property. It will always return the username.

@msmilkoff I’m glad this fixed your problem. I’ll publish 2.8.16 today with the fix.

Thanks for your workaround. It helped me have an idea as to how to prevent even though this is really Microsoft’s library’s problem. I’ll look into it and let you know what I find.
