did you made the same experience under xFlow working in a multi windows domain environment?
if you populate the users with domain e.g. domain\userid then xFlow is not able to create new tickets
following error message is comming up:
Exception occured in Create Actor recvMsg method java.lang.String cannot be cast to com.ca.ServicePlus.slump.BPObject
that problem is already known to CA - some votes could probably increase the chance to change this by design
