You can't do ...
... which is a boolean operation on strings. You need explicitly check the equality for each item and OR those results together, like ...
If Me.UserID = "Drb00" Or Me.UserID = "tep09" Then
Possibly 'LogInFrmUserIdTxt' is overkill, particularly if the item is a textbox on the Login form. Certainly there's no confusion about what the thing is, but it can make your code appear unnecessarily complicated. There's a balance somewhere.
You also might not need to explicitly use the .Text property. With textboxes you more commonly use the .Value property, which is the default and therefore not required in your code.
