1. the current installation of GLUU (3.1) has an issue where a user's email is case sensitive which causes some issues for users looking to reset their passwords, i just want to confirm if these are still case sensitive on version 4.3?
> No, in gluu 4.x, `uid` and `mail` are case insensitive.
2. Is it possible to change the message displayed when a user account is locked out?
> Can you describe a bit more what do you want to customize? You can customize a lot of things in gluu. such as customizing [public pages](https://gluu.org/docs/gluu-server/4.3/operation/custom-design/) , [interception script](https://gluu.org/docs/gluu-server/4.3/developer-guide/tips-cust-script-pages/), etc.
> Depending on the `support plan` we support many customizations.
