Category: Firebird Releases

People moving to FB 2.5.0 may be asking if it is safe to copy the security2.fdb file from previous versions of Firebird to Firebird 2.5, keeping the users previously created, so avoiding to recreate them.

In theory, copying the file should work, but with no guarantees. Firebird 2.5 uses a new ODS (11.2). You can do a backup/restore in FB 2.5 to update the ODS of security2.fdb, but some problems will still persists, regarding the use of the new role RDB$ADMIN (which gives SYSDBA rights to “normal” users) – in this case, normal users who were granted RDB$ADMIN role, will have problems to use the new SQL commands CREATE/ALTER/DROP USER. Note: Firebird 2.5.1 will bring a sql script to fix this problem.

So, the safest way to move users to FB 2.5 right now, is to recreate them in Firebird 2.5, either using gsec.exe or the new CREATE USER statement.

Thanks to Dmitry Yemanov for detailed information about the problem.
