It took me a bit to figure it out.

If you use local connections (/directory/whatever), then your baseline
authority is the file authority that you have as a linux user, with
firebird internal security applied on top of that.

If you use IP connections (localhost:3050:whatever), then your authority
is the authority that the user ID that launched firebird has, with
firebird internal security applied on top of that.

I have a user called "firebird", with its own home directory. My
databases are all encapsulated under the firebird directory. Firebird
(the application) is launched as a service under the firebird user

If I connect via IP connection, firebird has all of the authority it
needs. If I connect using just the file path, then my login's authority
is used. If I want to address something in the firebird home directory,
including my databases, then I must be a member of the firebird group.

hope this helps,
