Access to Database is denied by server administrator
This error usually means one of these:
1. The access is denied by option in firebird.conf. Please check the setting DatabaseAccess in firebird.conf to fix it.
2. Either you or the Firebird server doesn't have sufficient privileges on the database file. So, check the privileges (file owner and permission) on the database file and directory containing it and fix them.
Advice for Linux users:
It's wise to keep your databases in a directory with following permissions (770 in chmod terminology):
drwxrwx--- 2 firebird firebird 1136 2007-05-31 18:21 databases/
If it's a development machine and you wish to be able to manipulate files directly, add yourself to the 'firebird' group. Please note that you usually need to completely log off before the group membership changes are applied to your account on Linux.
As for the database files, use the following privilege (660 in chmod terminology):
-rw-rw---- 1 firebird firebird 6123520 2007-05-14 14:49 database.fdb
This ensures that only the firebird user (typically the one that runs the Firebird server) and members of firebird group (admins on the machine) will be able to access databases directly.
