I would like to add JDBC users on my website but it's impossible, CredentialsAwareLdapAndJdbcSiteAwareUsersManager is not modifiable.
Because it's a site aware user manager, I'm not able to create users by site admin, nor by CMS admin because add user button is not display and we should select which website is concerned by this user, nor on CMS user manager, I have not the button to add an user.

Also, org.ametys.plugins.site.users.SiteModifiableCredentialsAwareJdbc seems to be useless.
