DBSERVERNAME

After configuring interfaces for virtuals hosts (for webservers, say server1, server2) on a host (say host0), where two instances of Informix Universal Server are running, I get the error 956 client host or user (informix@>servername>) is not trusted by the server. <servername> is always the last entry for a virtual interface in /etc/hostname.hme0:<nn> What makes IUS believe, that a regular user locally logged on to the machine (say informix@localhost) turns suddenly into informix@webservername, when he tries to connect to a local database in dbaccess ? On two other machines with only one instance of IUS running (and solaris2.5.1), but lots of virtual interfaces, everything is fine. Could this be a problem of solaris 2.6 ? Configuration is Solaris 2.6 IUS 9.14UC1 The sqlhosts file is the same as on the machines with only one instance running, except for the additional entry for the second instance.
