-956 Trusted client error

Did an OnLine DSA 6.00 installation yesterday which worked fine with the server defined as onipcshm in sqlhosts, fine as onsoctcp and the server defined as localhost (the cop-out local loop-back connection!), but barfs on -956 (client is not trusted or some such) when you try to set up sqlhosts with the real hostname. Customer has apparently set Unix up for C2 security. finderr suggests adding entries to /etc/hosts.equiv. Tried setting that to 'hostname username' to no avail. /etc/hosts and /etc/services all check out OK. Any clues? akent@cix.compulink.co.uk (Andy Kent) ------------------------------------------------ Freelance Informix Database Specialist, Redland, Bristol, England
