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...
