GBAK with service_mgr and WinSSPI authentication for Windows SYSTEM user
producing error in clumplet API
--------------------------------------------------------------------------------------------------------
Key: CORE-6329
URL: http://tracker.firebirdsql.org/browse/CORE-6329
Project: Firebird Core
Issue Type: Bug
Components: GBAK
Affects Versions: 3.0.5
Environment: Windows Server 2016
Reporter: Sven-Eric Matthes
Hello,
last year I configured our databases for backups without having to write our
SYSDBA credentials in our backup script. Here I used Trusted Authentication via
the WinSSPI Plugin and mapped the Windows SYSTEM user to SYSDBA via Global
Mapping. We don't want our credentials in the script files because of security
policies.
This is the mapping I created:
CREATE GLOBAL MAPPING WIN_SYSTEM
USING PLUGIN WIN_SSPI
FROM USER "AD\SERVERNAME$"
TO USER SYSDBA;
I could then create or restore a backup by running my backup script as Windows
System User without SYSDBA credentials. This worked just fine with Firebird
3.0.4. Now I updated our Test environment to Firebird 3.0.5 and I'm getting an
error in the clumplet API.
For example when restoring a backup it returns this:
gbak.exe -r -se localhost/3050:service_mgr -v -y D:\Backup\SomeDB.log
D:\Backup\SomeDB.fbk D:\Database\SomeDB.fdb
gbak: ERROR:Internal error when using clumplet API: attempt to store 447 bytes
in a clumplet with maximum size 255 bytes
gbak:Exiting before completion due to errors
The same error happens if I create backups like this:
gbak.exe -b -v -y D:\Backup\SomeDB.log D:\Database\SomeDB.fdb
E:\Backup\SomeDB.fbk
If I backup or restore without service_mgr it works, but then it takes a lot
longer!
Did something break here?
