We are currently evaluating Parallels Plesk Panel 11, and we run into a problem.
For one of our customers we have to implement a hosting control panel, and they require the use of only alphanumeric usernames.
While trying to add a Subscription, we received the following error;
"You can use lowercase alphanumeric, dash, and underscore symbols in the username. The username should start with a lowercase alphabetic character and should be between 1 and 16 characters in length."
We are wondering why the policy of not being able to use alphanumeric usernames is active, and is there a way to change the configuration of this policy?
Hopefully it's possible to change the behavior, otherwise we have to evaluate other products in the market as well. Thank you for your answer in advance.
