allow_user_to_change_display_name

[volker-raschek]

Steps to reproduce

1. Set the config value allow_user_to_change_display_name=false; in config.php
2. Try to change the email address from an user in the admin panel. You can't change the email as admin.
3. Set the config value allow_user_to_change_display_name back to true in config.php
4. You can change the email address as admin in the admin panel.

Pleas fix this bug. If allow_user_to_change_display_name is false, only the admin can change the email and other personal settings.

@volker-raschek Can you provide more details? Used apps, possible error messages in your logfiles, external authentication, ...

[volker-raschek]

Yes very well.
I dont use an external authentication.

This is the message, when i want to change the e-mail address about the admin panel with the
allow_user_to_change_display_name = false.
http://666kb.com/i/dc9v4isvj2xbaz2j6.png
It's German and means, the email address can't be changed.
