I installed FreeRadius and the Webinterface Daloradius.
Unfortunately I'm not able to log in to <http://radiusip/daloradius>.

I always receive the error message:

Database connection error
Error Message: DB Error: extension not found

The Log always writes this, when I quit the Debugging (FreeRadius -X):

```
tail -f /var/log/mysql/error.log:

The Password is 100 % Correct in all necessary Config-Files, I deactived the Firewall. I think it has to do with not properly closing connections and/or wrong permissions.

The Permissions from The MySql-User are:

```
mysql> show grants;
+----------------------------------------------------------------+
| Grants for freeradius@localhost                                |
+----------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'freeradius'@'localhost'                 |
| GRANT ALL PRIVILEGES ON `radius`.* TO 'freeradius'@'localhost' |
+----------------------------------------------------------------+
2 rows in set (0.00 sec)

```

Any Ideas?

It is Ubuntu 16.04, Daloradius 0909 and FreeRadius V3
