We have a user that has had FB 2.1, and was running gbak with a command
line of the form:

>"C:\Program Files\Firebird\Firebird_2_1\bin\gbak.exe" -backup -verify

-Y "C:\ATBackup\AUCTIONTRACKER.LOG"
"C:\Tracker\Auct-Tr\AUCTIONTRACKER.FDB" "C:\ATBackup\AUCTIONTRACKER.FBK"

Note: Did not require -user or -password.

When he upgraded to FB 2.5, this command line format would no longer
work. It now requires the -user and -password switches with valid
username & password.

I've got a WinXP box set up with FB2.1, and a Win7 box set up with
FB2.5. I've run tests with successful backup under 2.1 with no
user/password; then ran it on my Win7/FB2.5 box and got the same result
as the user. Command line would only work with a valid user/password.

In neither case were the ISC_USER or ISC_PASSWORD enviornment variables set.

What's changed? Has the new version of gbak become more stringent? Any
clues appreciated.

Thanks
