Issue/Introduction

The following error is received while trying to take remote control of certain Agents:

"The Host's security configuration does not support Unified Logon. Please enter a username & password"

Reviewing permission configuration everything is correct and trying to take remote control of other Agents within the same group using the same user, works perfectly.

Cause

Reviewing TRC_URC_MANSRV_0.log, the following messages can be seen:

|INFO | CRCViewer::ProcessHostVersionInfo Host returned security Type? : managed
|INFO | CRCViewer::ProcessHostVersionInfo Host returned authority list? : unixl://agent.local,

WARNING| Unable to create a suitable authentication object for the user: winnt://domain/user
WARNING| No username was specified: Implies the host doesn't support unified logon

 

Environment

Client Automation 14 all releases.

Resolution

Based on the logs, it seems that a mismatch of Remote Control DB tables is present.

The way to solve this is to delete the Agent from DSM Explorer and then wait until it gets registered again..
