Your rating: None Average: 2.2 (38 votes)

Concern:

You are trying to add a Network Location on Windows Vista using HTTPS encryption to access the Document Infostore on OXAE as discribed in chapter "7.3. Accessing the Document Server under Windows Vista" on page 234 in the Usermanual but connection to the Server will not be established and connection between Client and Server fails with error message:

"The folder you entered does not appear to be valid. Please choose another"

Reason:
The usage of WebDAV via HTTPS on Windows Vista is linked to Internet Explorer 7. In order to use HTTPS to connect to the OXAE Server a Certificate is necessary which is issued and signed from the OXAE Server Certification Authority. For Internet Explorer 7 the OXAE Server Certification Authority is not a Trusted Root Certification Authority yet, hence any encrypted connection using the Certificate issued by the OXAE Server Certification Authority will fail and will be rejected not only for browsing in IE7 but also for accessing the Document Server OXAE.

As a user of Internet Explorer 7, you can work around the compatibility impact of HTTPS Security Improvements in the following ways:
If the certificate was not signed by a trusted certification authority, you can add the certification authority if you trust the authority.

Trusting a malicious certification authority will put your computer at risk, so use discretion. To add a Trusted certification authority, continue navigation from the Certificate Error page, and then click the Certificate Error button in the Internet Explorer address bar. Click the View Details link. On the Certification Path tab, select the root certificate and click the View Certificate button. On the General tab, click Install Certificate.
