Unfortunately while I recommend Zentyal, I recommend it based on others I know and trust - I've never actually used the product myself.
Any person who wants sanity in their data centers are going to stick with LTS releases - for their longer support, and the requirement to upgrade comes much less frequently. In theory the platforms LTS releases are built on are more stable as well. So I would strongly recommend sticking with LTS releases on the server platforms. Upgrading every 6 months on the desktop version isn't so painful, but doing it on a production server environment is crazy .
OK, I will roll back to 10.04 in the upcoming holidays. However, I have one more question. I want to create multiple phpmyadmin users, so that users will have access to their database only. Do you have any guide?
I sorted out that mulitple user issue. I don't know whether it is a real problem or not. My phpmyadmin.conf was having a <?php in the beginning of the file, but there was no ?> at the end of the file. I just added that tag, and created a database user from the phpmyadmin and it works.
However, I have one doubt. Why it was not giving me any error before?
Hey one more thing. Have you gone through this guide -
It is having all the information required for configuring Ubuntu 11.04 server and according them it works perfectly. This is the only guide that motivated me to go for the Ubuntu 11.04 server, instead of its LTS version.
I also tried to contact them via email, but didn't get any reply from them.
