Subject Firebird 2.5 Linux Red Hat 7 - Permission denied

Hi to all

I'm having an "Permission denied" issue with Firebird 2.5 super-server in a Linux Red Hat 7 box.

I can only read databases located on /var/lib/firebird/data. If I locate the same database in any different directory, when I try to access it using isql I get a "Permision denied".

I have checked the directory ownership to firebird user, the appropiate permissions of the directory to 770 and the permissions of the database file to 660

I checked the setting of DatabaseAccess variable in the firebird.conf file and it is in the default value.

I can't understand what is going on, and have no other idea on how to fix this.

Any help will be appreciated.
