With one of the ServiceDesk Plus installations, I am having trouble configuring the SSO. Here is what happens:

When SSO is enabled, SDP hosted server gives an error "The trust relationship between this workstation and the primary domain failed". In order to fix this, we need to decommission this host from the network and then re-join the same to the network/domain. Plus, all the printers installed in the user systems go offline and none of the (300) users are able to print.  

All this happens only when the SSO is enabled and if I disable the SSO, SDP is working fine and the printers as well. 

Did anyone come across any such issues in the past and have any suggestions / troubleshooting that I can try? 

Thanks much,
Sudesh
