[Samba] Failed to set servicePrincipalNames error

[Wayne Rasmussen]

This weekend upgraded a Solaris 9 system which has been using
samba-3.0.10 for a while without any problems to version 24 with patches
applied. When joining the domain there is a Failed to set
servicePrincipalNames error message.  It seems that the
/etc/nsswitch.conf is being ignored, but I can't be 100% certain of
that.  

As a workaround had to change /etc/inet/hosts
from:
10.10.10.91     mcsjump      loghost
to:
10.10.10.91     mcsjump.adtest.com mcsjump      loghost

Will be doing further testing...
