Issue/Introduction

After upgrading to DLP 16.0 or DLP 16.0 MP1, when you attempt to login to the Enforce Console you see an error message (this may tell you that the "login failed", or it may tell you "page not found"). After clicking the button to return to the login screen (or return to enforce), it will actually log you into the console. However, please note that even after it takes you into the console, you are not fully logged in and this may result in additional problems down the line.

Cause

This appears to be caused by session issues related to the URL being used.

https://<EnforceServer>/ProtectManager/logon

If you use the above URL directly or in a bookmark, it appears to be holding on to the old session even after clearing browser cache or using incognito mode.

Resolution

To resolve this issue, we simply need to use a shortened version of the URL...

https://<EnforceServer>/

This forces it to create a new session before taking you to the logon page and you will no longer see the error messages, and you will be properly logged in.
