How to edit online documents in MS Office without prompting for login and password?

Install version of alfresco-community-installer-201704-linux-x64.bin

After logging in to alfresco / share / page / I choose any doc document.
I choose "Edit in MS Office" menu, the first prompt to open a file from an unconfirmed source and the second to enter a login and password appears.

After completing the login data, the document opens for editing.
Users in / share / authorize to use ldap-ad (windows server 2012 R2).

I have seen many examples unfortunately did not work properly.
The SSL proxy I have configured on nginx.
I have never been able to authorize by sso.

Examples of working configurations are welcome ;]

How can I get rid of both messages ?

You need to enable and configure either the passthru or kerberos authentication subsystem to enable SSO. Just using ldap-ad will never work without the login prompts. In addition, your clients need to be configured to trust the Alfresco host (typically Trusted Intranet Zone). You should also use SSL with a proper certificate (not self-signed) since newer Windows versions (7+) won't allow/trust non-encrypted connections to use integrated authentication by default.

Progress. Actually, as I added to the trusted zone, this is less than an SSL request.

Suppose you disable sync with ldap and logs in as an administrator, local user.
Can I disable the prompt when editing an Office document for my alfresco (www) users, windows users in AD?
