We have been configuring Alfresco Community 7.3.1 with Kerberos SSO enabled. It works pretty well, we can access Share, Repo, WebDav and AOS via browser without a credentials prompt.
Also, we can mount Alfresco as a drive via WebDav and AOS.
However, if we try to open an MS Office document via AOS (using the "Edit in MS Office" action on Alfresco Share or directly from Windows File Explorer) then the login window appears.
There are 2 weird things there:
1. If we close the popup without entering login/password then the document loads successfully and it can be edited without any problems. The document gets locked in Alfresco Share until editing is finished and the version of the document gets updated. So, all works correctly except for the login prompt.
2. When we open a document via /alfresco/webdav/ the login popup doesn't appear.
3. There is an old alfresco installation that is configured the same way and the login prompt doesn't appear when we open files via MS Office.
- Ubuntu Server
- ACS Community 7.3.1.
- AOS 1.6.0-M1 (tried v1.5.0, v1.4.0)
- Tomcat 9
- NGinx + SSL
- Kerberos SSO
- Windows 10
- MS Office 16
Could someone advise where an issue might be? Can it be a bug in AOS? Or is it a misconfiguration of the client or the server?
