When trying to connect with his admin account the user receive the following error message :
00 Internal Server Error | The server has either erred or is incapable of performing the requested operation.

Only this user is impacted. No other user reported any trouble.¶

From the log on the machine (/home/rcserver/.rccontrol/enterprise-1/enterprise.log), I can see this stacktrace:
