Carsten, I answered this question at least 3 times in this least an
7.1. too. There was some tech problem this day if I recall correctly.
So, I repeat

it's inherited from bug in RC1 gbak. Before backup databases
which were restored with it, make
Delete From RDB$GENERATORS where RDB$GENERATOR_NAME='RDB$SECURITY'
(not RDB$SECURITY_CLASS !!!)

Can't say what you can do if you have gbk only. But change RC1 for
RC2 don't require b/r. If you have previous instance of database, you
can access it with RC2, make what I said and backup it once more.
