Hi,
For the record of others, Ahmet was modifying the shiro.ini file from the Opal distribution folder (/usr/share/opal that contains the binaries and the default config), instead of the one from the Opal local installation: /etc/opal.
Following the common layout of application installation on linux systems:
/usr/share/opalis the distribution folder (replaced when upgraded)/var/lib/opalis the local data folder/etc/opalis the configuration folder/var/log/opalis the log folder
Regards
Yannick
