    Hey,

    We use a little bit different approach for user logon - they provide email address (instead of username) and password  (to simplify: email address is username).

    We ​have also Ldap membership provider enabled and we allow ldap
    users to login on the front-end. Everything works fine, but admin users
    can create accounts in the backend (Sitefinity admin), and we need to
    restrict email addresses to be unique (in other words: admin cannot
    create a new user with email address that exists for Ldap user). We implemented this on the front-end by checking with LdapMembershipProvider if provided email address exists, if not then we call CreateUser on UserManager, but we cannot ​add any custom validation ​in Sitefinity backend to create user form.

    Is there any possibility to achieve this ?

    Thank you,

    Albert

    Hello Albert,

    In order to achieve your need you can set the username and the nickname as the user's e-mail address.

    In that case users with one and the same e-mail could not be created in any membership provider.
