Unable to log on to the ePO console (after you apply ePO 5.10 Update 4 or 13 and when users use Windows authentication)

Technical Articles ID: KB91734

Environment

ePolicy Orchestrator (ePO) 5.10.0 Update 4 or 13

For details of ePO supported environments, see KB51569 - Supported platforms for ePolicy Orchestrator.

Problem

Users who are configured to use Windows authentication are unable to log on to the ePO console after you apply ePO 5.10 Update 4 or 13.

This issue occurs on systems where Advanced Windows Authentication has been enabled by renaming winauth.dll; the update is then applied.

NOTE: If you haven't enabled Advanced Windows authentication in this way, this article does not apply.

System Change

You applied ePO 5.10 Update 4 or 13.

Cause

This problem occurs because in certain cases the ePO 5.10 cumulative Update 4 or 13 package installs a new copy of the following two files:

winauth.dll
winauth.dll.sig

The update package installs a new copy of these files even if the files have been previously renamed or removed. This action changes the method used for Windows Authentication, which causes logons to fail for accounts using Windows authentication.

Solution

Re-enable Windows Authentication by renaming winauth.dll again.

For help, see the "Enable Windows authentication in the McAfee ePO server" section in the ePO 5.10 Product Guide.
