This is very weird.
Just installed the latest version 1659. I then logged into an existing BS using the built in account admin and password of password. I ran a process which I've used before to add some BO records. A rule on the BO sets an attribute to LoggedInSystemUser.LoginName.
Previously this attribute was set to
admin
This time it sets it to
BAS_Guest@@
Whats the go?
Cheers Rod
