I've just installed a fresh I-DOIT 1.48 on Ubuntu 14.04 LTS and ran into some problems connecting to our OCS 2.1 RC1. Running on a seperate server, the OCS has been in use for some years now without any trouble. To connect the i-doit I created a user in MySQL on the OCS server and allowed external access. This configuration seems to be allright, because I can login and obtain data when I connect from the I-Doit Server Command Line:

hr]

root@xxxx:/var/www/html# mysql -u idoit -p -D ocsweb -h 192.168.0.5

Enter password:
Reading table information for completion of table and column names

mysql> show databases;

| information_schema |

2 rows in set (0.00 sec)

But when I configure these settings into i-doit GUI I get an error: "Could not connect to OCS database"

Is there a detailed log file to figure out the reason causing this error? Are any special rights need for the MySQL connection?

Thanks in advance - any help is much appreciated
