Nice paper Milan....are you aware of the Firebird documentation project?

Don't we all hate the way good stuff is dispersed all over the web !

I have taken the html from your site and plonked it provisionally
into the "papers" section of my local copy of the "manual" section of
the CVS tree. It needs a little work to get it into Docbook format,
which I'm willing to do if you can't do it yourself...but the html is
good and clean, so it won't be a huge task. It's highly desirable to
do it this way as it ensures consistency and makes updating and
translation a breeze.

That might have to do with the logged-in Linux user's file
permissions. Unlike "full server", Embedded on Linux access the
database file directly, so the logged-in user needs the proper
permissions at both folder (rwx) and file (rw) levels. So, if the
logged-in user belongs to a group that has these permissions at group
level, everything should be like chocolate mousse.

Well....it would save 600K on disk but it would break the current
authentication model. Fb 3.0 will have more authentication options.

I wonder whether you (and Milan) know that you can set up the Linux
user in the Firebird security database so that, if the Linux user is
already logged in, it won't have to endure separate authentication
when connecting to Firebird? Milan, this would be worth adding to
your paper, with perhaps some reference to SQL privileges and Roles...
