Command ant add-spadmin-user is not taking the expected effect. It's not setting the user as Catalog administrator user
There were differences in the email address from the Active directory, Service Catalog and Serivce Desk Manager user ccount. The email addresses were not match.
In the ant add-spadmin-user command he was getting the error: [java] faultString: Exception occurred editing user: Email format is invalid
This was resolved by setting the email address exaclty the same in Active Directory, Service Catalog and Service Desk Manager users.
