When I attempt to add an Active Directory user to the Contributor group for a Project, I receive error
"TF20507: The string argument contains a character that is not valid:'u0009'. Correct the argument, and then try the operation again. Parameter name: value"
I think this may have something to do with one of the Active Directory fields for certain users having a tab char embedded. We have 3 users who experience this issue. The other 200+ users can be added with no issues.
