# Modifying global user settings
|
|
|
|
GitLab administrators can modify user settings for the entire GitLab instance.
|
|
|
|
## Disallow users creating top-level groups
|
|
|
|
By default, new users can create top-level groups. To disable this, modify the appropriate configuration file,
|
|
and then [reconfigure and restart GitLab](restart_gitlab.md).
|
|
|
|
For Omnibus installations, add the following to `/etc/gitlab/gitlab.rb`:
|
|
|
|
```ruby
|
|
gitlab_rails['gitlab_default_can_create_group'] = false
|
|
```
|
|
|
|
For source installations, uncomment the following line in `config/gitlab.yml`:
|
|
|
|
```yaml
|
|
# default_can_create_group: false # default: true
|
|
```
|
|
|
|
## Disallow users changing usernames
|
|
|
|
By default, new users can change their usernames. To disable this, modify the appropriate configuration file,
|
|
and then [reconfigure and restart GitLab](restart_gitlab.md).
|
|
|
|
For Omnibus installations, add the following to `/etc/gitlab/gitlab.rb`:
|
|
|
|
```ruby
|
|
gitlab_rails['gitlab_username_changing_enabled'] = false
|
|
```
|
|
|
|
For source installations, uncomment the following line in `config/gitlab.yml`:
|
|
|
|
```yaml
|
|
# username_changing_enabled: false # default: true - User can change their username/namespace
|
|
```
