Hello, I am experiencing a problem with remote management when having
workstations, two servers with ZCM 11 and a separate server with MSSQL.
When trying to manage workstation connected to the other ZCM server, I get
this "Authentication failed" error:

I've read, that it could be because of bad time synchronization. But in this
environment, all servers, as well as workstations are synchronized to same
NTP server and clocks have same time. Is there something else, that can
cause this error? Thanks in advance.
