To be honest, I don't know Syteline 5, but if you are using an ODBC-connection to access a Progress-database you have to grant SQL-rights.
When you create an _user "sysprogress" with password "sysprogress" (encode("sysprogress) in 4GL) and log-on to the db with that user, you should be able to grant rights and I think view them too.
In the Progress SQL Explorer (or through an other ODBC-connection)
select * from systabauth
