I have installed a two node (load balanced) Workflow Manager Farm in Azure, which of course uses Service 1.0 under the hood. Everything appears to be running fine (my message traffic is being distributed evenly between the nodes. The machines have exactly the same software on them to my knowledge (Windows Server 2012, and SB & WF 1.0)
However, I am seeing warnings on one machine (the first one I added to the farm) in the Applications and Service Log for Microsoft Service Bus:
Security Token Service warning: System.DirectoryServices.AccountManagement.PrincipalServerDownException: The server could not be contacted. ---> System.DirectoryServices.Protocols.LdapException: The LDAP
server is unavailable.

properties)

It is just a warning but it is being written to the event log every 7 or 13 minutes (it alternates) and it is only happening on one of the machines. Note that the two machines are in a Work Group. Is this a known issues or anything I should worry about?
Thanks, Rod
